Pretty simple. What works on your rig? Size, miles out of, noise on highway, grip, what terrain they work best on, etc....

Keep it based on personal experience.

Excellent topic, since I am about to buy new ones, but I dont think its going to be a simple one. Mud/rock/sand/street/dirt roads, I dont think there is one tire out there that covers everything we do...

Currently I'm thinking of either going with Cooper Discovery STT's again or KM2's, whatever I go with though I dont want directional tires.

35" KM2's. Not sure on mileage, but not much. Highway noise is actually very minimal. They have worked well on all of the terrain I've taken them on so far, slick rock, dirt, dry rock. Surprised at how well they worked in snow and ice as well. Definitely a major improvement there over the old KM's. Been happy with sidewall strength as well so far too.

Terrain: East coast style -- pretty rocky and woodsy, but still a lot of slick mud. After rain, the trails increase in difficulty due to lack of traction on the dirt and on the rocks.


Tires I have run:

31x10.5x15 BFG ATs
Great all-round tire for the occassional wheeler. Not a great tire for the terrain here, but it gets the job done if you are DD'ing your rig and only get out a few times a year. The tire is great in the snow/ice

31x11.5x15 Swamper LTBs
IMO, it's the best tire hands down in the 31-32" tire size when you are only concerned with east coast wheeling. They have an extremely aggressive tread pattern and strong sidewall, so they flat out suck on the road. I'd really only recommend these tires for "short" wheeling trips. I did an unplanned 6 hour trip on them and it wasn't very pleasant. For longer trips, I would normally throw these tires in the back and drive there with my BFG ATs.

33x12.5x15 Trxus MTs
I was pleasantly surprised with these tires. I got a smoking deal on these new that I couldn't pass up even though my rig was a trailer queen. For a mud tire, they drive great on the road. My buddy didn't have any issues balancing them, but I've heard that I may have just been lucky in that regard. They gripped really well in the rocks and held their own in the mud (weren't as good as the LTBs, though). For what little street time they did see, I wasn't too happy with the treadwear and my other friends running the same tires had treadwear issues, too.

Now I did tear up three of them (I had a warranty on them, so they were replaced for free), but those were all my fault. The first two I tore on the same run through the woods. It was a local competition, so I had quite an iron foot. Wheelspeed at 8psi with a lot of hidden roots, rocks, downed branches, doesn't bode well for many tires. The last one was a result on my driving on it flat for over a mile with a broken valve stem. A bunch of mud got inside the tire as a result and tore up chunks from the inner sidewall. My buddy did not feel comfortable re-mounting it with the inner sidewall damage.

36x13.5x15 Iroks
I never really liked these tires, but they were also very worn and the beads had some issues from all the times they were mounted before, so the beads leaked a bit. They were great in dry rock and snow, but weren't too great in muddy rocks. The sidewalls softened up quite a bit, so they aired down really nicely. Despite running them at about 6 or 7 psi most of the time, I never busted any of them. Considering their price point, they are definitely not a bad choice, but not the best out there for the east coast.

35x12x15 Swamper LTBs
Hands down the best tire I ever ran. Pearce commented at GSSE last year how "sticky" they were for 35s. The only reason I got rid of them was because I wanted to run 17s and at least a 37" tire for the tire swap.

37x12.5x17 Trxus MT Stickies
Sitting around right now. Looking forward to trying them out once I get back on the trails.

Hands down, 39" reds. They're amazing on rock and for general trail wheeling. I have never run a tire even half as good as a sticky bfg. Highway? I live in the world of fun per gallon. These are not commuter tires.

I'm running 42x16 pitubll rockers and they work very well all around. I haven't really been thrilled with the sidewall strength but so far I've been able to tear sidewalls in every tire i've run to date, i've run 37 mtr's and cut 3 out of 5, i also ran some 38 tsls for a while, managed to cut 2 of them and even cut an inside sidewall..go figure that one..

The road noise is very minimal, although i've spent very little time on the pavement they are much quieter than the tsls, the mtr's were very quiet as well.

I love the traction of the PBR's, they stick to rocks extremely well and work as good as can be expected on the super slick east coast mud too, i would recommend this tire, although the costs have increased significantly since i bought mine. They are a very lightweight tire for their size at 95lbs each, where a 42 tsl weights 115 (IIRC).

They seem to be a good medium between a sticky an off the shelf tire..

33" old style MTR's - went through 2 sets of these. They got the job done and I thought they were OK before I really got my hands on some better tires, in retrospect they didn't stick for crap.

After that I got 35" Super swamper SSR radials. These were...OK. Even at low pressures the tread didn't really conform the way my other tires have, and I slipped a few beads but theres a catch. The one I ran was a 35x12.5x16 with some insane load rating. They weigh 87lbs a piece new, max psi of 65 with max load of 3640 lbs so it seems to be more of a tow rig tire, hell they wore great on the road because of it, probably would have got a ton of miles out of them if I wore them all the way down.

Now for my favorite tire...my current 36" irok radials. They work great on all the terrains I encounter (dry granite, wet but not muddy rock, snow) hands down better than all the other tires I've run. The group of guys I wheel with went through a total of 3 sets of 36" bias in the past, and I can say these are NOTHING alike. The road manners are nothing short of incredible for a swamper. I drove the jeep down to KOH, 1000 mile round trip, and was able to hold 75MPH constant comfortably pretty much the entire trip, at that point I'd start to get a very subtle shimmy in the steering wheel. Can't complain though, they haven't been balanced in over a year and I know at least 1 is off. I bought the tires used with like 95% on them, been ALL over california driving thousands of miles wheeling the hell out of them and still have 65%+ tread compared to old bias's which you could visually watch the tread depth change through our trips.

OH and I can't recall ever slipping a bead with the Iroks yet. I run them around 11-12 PSI in the snow and rocks usually, though I've been creeping lower and lower until I start running into issues

Gonna be based on opinion and where you wheel for sure.

Trxus MTs 265/75/16 Worked well in rocks and Moab. Semi-out of round and not too nice on the road.

MTR's old style 285/75/16 and siped. Worked well on rocks and Moab. Great on the road.

LTB's 34x10.5/15 Sucked on rocks, sucked in Moab, so I siped them. Still sucked on the rocks after siping. They were also out of round (eggs) and sucked so bad it hurt on the road. Sold them and went back to MTR's.

MTR's old style 35/12.5/15 and siped. Work great on rocks and Moab! Never a side wall issue with any of the MTR's.

Next tires - I'm looking at the new MTR's with Kevlar, just can't decide if I should stay with 35's or jump to 37's. ;)

On emy second set of Trxus MTs, first were 31x10.5s and current are 35x12.5s.

For over all performance I have been happy with them. Road noise is minimal. The sipping help them in wet situations, but like others have said, they are not deep mud kind of tire. Balancing is an issue, so instead of weights, I have used airsoft BBs and I have not noticed any problems since.

31x10.50 MTR - Loud, cupped badly, gripped ok off-road but not impressed on wet/snowy roads.

31x10.50 BFG TKO - Lasted a looooong time. Good wet traction, ok snow traction, off-road were good, unless you were on rocks.

34x10.50 LTB - Beast on rocks. Loved them! Super tough. On road, very bad. Clunking when cold, hard to balance, not as loud as MTR, wore quickly, bad wet/snow traction.

Perfect timing on this thread.

The Polar Bear has 33" BFG Mud Terrains - for rock and mud they seem to work great, for snow and ice, they are atrocious. I can't get traction in 4wd to save my life with these. Since it's starting to warm up I'll probably keep them through the summer and start looking for a different set in the fall.

The Rock Limo has a cheapo recently discontinued set of 35" Dunlop Mud Rover Maxx Tractions. I wasn't terribly impressed with these, although I have only wheeled with them a couple of times. I got a pierced sidewall in one not too long ago and haven't found any matching to replace it. I'm leaning towards selling the remaining three and buying a full set of MTR Kevlars...

How are the MTRs in snow and ice? How about road noise. I don't own a tow rig yet so my Jeeps all still see long highway miles to the wheeling spots.

My Experiences

BFG AT KOs (31s) I only ran them a short time but have to say they were a good all around tire, good snow, good trail duty including slick rock, great highway tire. Not so good for mud as they were not very good at self cleaning. I would buy them again and recently had them on my 78 F150. They make a good truck tire that sees double duty with an emphasis on street.

Truxus MTs (32s) Good offroad and sticky on the rocks. I had a lot of chunks come off the tread and at first they were decent on the highway but later were noisey and hard to balance. I would not buy them for a double duty rig. Trail only would be considered.

Firestone MTs (32s) These had good traction offroad and in the snow. Not as good on ice other MTs I have owned but doable. Decent highway use but got noisey with more miles. The only offroad tire failure for me was a severly damaged sidewall with these. I do not necessarily blame the tire as I was behind the steering wheel when it happened. I would not buy them again, but would not tell someone not to either.

MTRs (33s) Good offroad including rocks and slick rock. Good tire in the ice and snow too. Long lasting with decent higway maners. I would buy MTRs again and would use for double duty street/trail.

BFG KM2s. (33s) These are what I have now. Good trail tire in rocks, slick rock and mud. I like them in the snow and ice too. Great higway maners and quiet for an MT type tire. They are getting louder at around 15k miles then when new, but still decent. I would buy these again no problem for both street/trail use.

I think for tires in rocky areas like the South West you will want a MT type tire with a reinforced sidewall. There are fewer options than you might think and more expensive. I see a lot of bargain type MT tires that I am sure ok for mud and sand. However I see in almost any large group trail run someone damage these types of tires in this area do to rocks. Most of the time climbing an obstacle and the tire get pinched or rubs a sharp rock. Therefore every tire I have purchased for my Jeep the first consideration was the sidewall then the tread.

Tires I am familiar with that have heavy duty sidewalls:

BFG
ATKO
MT
MT KM2

GoodYear
MTR
AT Silent Armour

Interco
Truxus MT
I am sure others too

Firestone
Destination MT - again only sidewall I have damaged beyond repair

I know there are others too.

Have there been instances where you think your old LTBs would have performed better? I'd suspect slimy hill climbs or deep mud... For all intents and purposes, the Red Labels are running on the same setup as your LTBs did, right?

Almost none. There was one time that someone stopped unexpectedly in front of me on a steep hill and I had to stop to avoid a collision. Could not turn around or back straight up due to deep ruts, and couldn't start from a dead stop. The LTBs might have been able to get me out of that situation. Other than that, the reds perform better on everything.

They are so much lighter that I can put noticeably more power down too. Now I just try to flutter the throttle on slimy hills so I can generate wheelspeed on demand when I need to power through a low traction section. On rock just about any driving style works. That was not the case with the LTBs.

I'll report on the tires I've run

BFG All-Terrains, stock 235/75/15 and now 32x11.50/15. I was really unimpressed with the set of stock-sized ones I ran. They were loud, wore like crap and didn't do nearly as well as everyone said they would in the snow. Now I'm running a set of 32x11.50/15s for street use and so far I've been extremely happy with them. Tire selection in 32x11.50/15 is very limited so I made the choice based on availabilities. Maybe going from MTs to ATs changed my mind but they are quiet and have done well in the little bit of snow we've had this year.

Trxus M/T. I replaced the stock sized BFG A/Ts with these when I initially lifted my ZJ with a set of 31x10.50s. On road these rode well but were loud and didn't wear that great. I think I sold them with 20k miles on them and they had maybe 10k left in them. In the winter they did exceptionally well. Better than my first set of BFG A/Ts and there successor, the KM2s. Off road they also did really well. I had about 3 or 4 trips to the Badlands on them as well as several trips on some trails in the UP. I would say for a mixed terrain radial tire they are about as good as it gets. I have considered getting another set when the KM2s wear out but I don't think I will as I now have street tires and can go more aggressive on my next set of M/Ts.

BFG KM2. My set of trail tires are 285/70/17 KM2s, load range D. I have been extremely happy with them. I have almost 20k road miles on them and they don't show much wear at all. They are surprisingly good in the snow, and I've had it through a couple of harsh winters in MI's UP. There were hills my wife and roommate couldn't make it up with FWD cars that I could make it up in 2wd. As far as wheeling goes, they don't have a ton of trail miles on them, but I have been pretty happy with them for the few miles they do have. The trails they were exposed to were mostly a combination of rocks mixed with dirt and mud.

33x12.50 bias-ply TSLs on 8" wheels. For the 'wheeling I did in Wisconsin they worked awesome. This was a combination of loose rocks, downed trees, stumps, big rock fields, and muddy trails with a combination of the above conditions. Aired down to 15psi they seemed to stick like glue. Lower than 12psi I would slip beads on downhill stretches. I am anxious to get them on the trails here in Colorado. Loud as hell on the road. Currently balanced with airsoft BBs, and it has made an incredible difference. Still start out square in the morning, but after a mile or so they ride so much better than they did with wheel weights.

33x9.50 BFG A/Ts. Good road manners, decent in moderate trails. Footprint is lacking for some places that I can easily drive with the Swampers, but that's not what I got them for. As a DD tire they are the best out of these 3 sets that I have run. Hardpack, dry conditions these work as good or better than the Swampers, although not very good for sandy conditions, again the narrow footprint is not very helpful. Also balanced with airsoft BBs.

32x11.50 Trailhandler A/Ts. This is the second Jeep I have used these tires on, bought them from Sears and I believe they are discontinued. Not as grippy on hardpack as either the Swampers or the BFGs. Better in sandy conditions than either one of the others. Tread pattern is very mild, noise is non-existant. Going to use these for the trailer I am going to build.

I've only run two different types, but I haven't seen either reviewed yet. I've wheeled in New England only.

1. Cooper Discoverer STT 30x9.5R15: This was the first set of "real" tires I had on the ZJ. I was stupid/broke enough to never rotate them, but got 30k out of the fronts before they were toast due to alighnment/wheel bearing issues. Traction was good at street pressure (never aired these down, as it was mostly stocker wheeling) and never had an issue clearing mud. Rears had 50% tread on them when the fronts were done, so I don't see why I wouldn't have gotten 10-20k more out of these without front end issues. Tolerable on the road and didn't have a problem with mounting or balancing.

2. BFG MT (JK Rubicon Pattern) 255 75R17: Running these currently on my ZJ. On road manners and road noise are awesome. MPG has been anywhere from 15-18 with 4.10 gears and 4.5" of lift, which is nothing to complain about. They weigh in at 75 pounds per corner (Wheel, tire, spacer) so I imagine that has a lot to do with the good mileage. I bought the tires with 3-4k on them, and have put approximately 30k on them and I wouldn't be surprised to get another 15-20k out of them. Off road, they leave something to be desired. I wheeled them at 20 PSI, 18 PSI and 15 PSI, and I couldn't get the traction I wanted out of them in a lot of situations. The extra bit that is added into the JK-specific tread didn't allow them to bite as well on the rocks, and I really wasn't comfortable running under 15 PSI due to the small sidewall. I will be keeping these around for inspection/road miles, however.

3: 35 12.5R15 MTR-K: Picking these up this weekend.

The tires don't grip worth shit in snow and the sidewall is super stiff. Also the H1 wheels need to be recentered for any sort of decent offset, otherwise your hub becomes a rock magnet.

I freakin hated mine. The tread was chopped a bit when I got them so maybe that had something to do with it but god what a noisy POS tire IMO. We have people in at the dealer all the time with issues steming from these. They were 2x as noisy as the treadwrights I have now.

I guess I'll jump in here too! I have never run a tire on my rig more than 1-2K miles so...

:confused:BFG All Terrain- 31/10.50/15: Do not belong on an off road vehicle. other than that were pretty good on the road and look good too ;-) I used these for about 1/2 season before going to...

:smt071Good Year MTR(old style)- 33/12.50/15: I got a free set well used evenly worn and had about a 1/4" tread left. Basically worthless, wheeled them maybe 5 times.

:smt018BFG Mud-Terrain(old style)- 33/12.50/15: These were also used only about 5 times. I sold them promptly! They were really good at what you would buy the BFG All-terrains for doing.

:) Truxus MT- 34/12.50/15: These stuck like glue in CO rocks and Moab. They did chunk quite a bit and got really out of round in only 2 seasons.

:) Swamper TSL- Q78-15(35.5/11/15): Absolutely great in the CO rocks decent in Moab. Pretty much horrible at hwy driving.

:( Swamper TSL radial- 33/10.5/15: good in mud but can't say were good at anything else.

:supz: Mickey Thompson Baja Claw radial- 35/12.5/15: Absolutely phenomenal tire. I wheeled these on every surface possible for 2 seasons and all I can say is WOW!. On the road they are a bit loud, off the road they grip rock like it is going out of style! I have had the sidewall of these tires completely folded over and pinched between rim and rock and come out without a scratch. I ran them without even balancing them and never noticed. The bead is so strong I never once blew this tire off the bead. They did chunk a bit but here in western CO the rock is shaaarp. I would definitely buy again.

:D Yokahama geolandar AT-S- 285/75/16: This is a true all terrain tire. I have these on the ZJ now and have used them for almost a year. I use this Jeep for mostly camping, light wheeling, driving to and from the trail, Wife's heavy snow day DD and these tires do it all. I showed up to run Pritchett Canyon, Moab, last year and almost got laughed off the trail. But as the trail leader they quickly shut up ;) I only winched one time as I was wedged in on the right side of yellow hill. I would suggest these tires to anyone looking for a true all terrain tire.

I am getting ready to purchase a new set of MT's 315/75/16 for the ZJ and am thinking of going with the new Cooper STT's or the Baja MTZ's any reviews of either of these would be great.

Thanks,
Clint

Nice topic...this should basically end up being a "be all end all" discussion on tires.

I've ran 235/70R16 BF Goodrich A/T's; Great in snow and rough, dry terrain but not "great" in mud. I've wheeled this small tire size in 7" of snow off road and not got stuck. Ran them through some pretty thick strip mine mud (any one from the east knows what I'm talking about) and still didn't get stuck but I was not confident and they didn't clean out well.

Current off road tires; 31" KM2's and so far have been a great tire. I'm fully confident that they will serve me well in this nice western PA mud. At around 5 mph on dryer or more solid surface on the trails the mud will literally fall off like hot butter...no worries about cleaning out with the I6. I would like to test them on some rocks at Rausche Creek (not sure if gas prices will allow that trip though) because the KM2 looks like a pretty decent rock tire. The only disappointment I've had with them is the snow...my A/T's showed these up like I was running summer tires. However, they're an M/T so I didn't expect much and I also wasn't aired down (running 50 psi).

It depends on tire size and load rating as much as it does the vehicle they're on. I'll agree that 50 and even 40 is high, but I run my load range C 32x11.50s at 35 on the street. Under inflation can cause just as many wear issues as over inflation can.

I have run BFG AT's, KM2's and Pitbull Rocker radials on my ZJ.

BFG AT - 245/75/16" (IIRC) load range E. These were used when I towed with my ZJ. Good stiff sidewalls and plenty of strength. They rode decent, fairly quiet, wore evenly and did ok in the snow. I got lots of miles out of them (around 45K) before I sold them with about 5-7K left on them.

KM2 - 305/70/16 (35"). Great all around tire. Quiet on the highway with just slight tire noise at speed and around 10mph. Good grip in rocks, decent in mud. No experience in the snow or sand. Got about 8 or 10K miles out of them before going to a larger size. I'd say they had about 25-35K left on them.

Pitbull Rockers radials - 37/12.50/17. Great off-road tire. I have been really happy with these tires. Great traction in everything I have done. These days I don't street drive my ZJ much so I have know idea about tread wear. They are fairly loud on the road at 60ish. I did manage to cut a sidewall last trip out but I'm not sure any other tire would have been any different as it was a sharp slice and not a gash. They also measure out to be just about a true 37" tall. I have run them at 5 psi and they gripped like crazy but I typically run at about 8 or 9 to keep some sidewall stiffness for stability for going faster. I would buy these tires again in a heart beat.

40 is still retarded high. I run the 37's at 22psi on road, 10psi off and run my beadlocked 35's 25psi on road and 5psi off. I guess 50psi is cool though if you hate the way tires with tread look.

We run 30-35 on road, but when we drove it we did 40 once or twice.

Why are you running so much pressure?


The KM2 says "Max 50 psi"...I just figured these were like normal tires and you run a higher air pressure while on road.

A portable air compressor is on the list of (many) things to purchase so I can air down on the trail and not have to drive home on deflated tires.

Another dude I wheel with has had Nitto Terra Grapplers for a year and half at 50 psi with absolutely no wear problems...in fact they have quite a bit of tread left.

I'm sure 32 psi feels much, much better on the road however.

285 75 16 Treadwrights:

Fairly quiet (hum at hwy speed)
Wearing extremely well so far
MT tread
Look pretty cool too
Havent wheeled with them yet ;(
An actual 33" tire measuring in at 33.2"
BFG carcass


31x10.50x15 Treadwright
Old MTR tread
BFG A/T carcass
20/32" tread depth new
18/32" with 15,000 miles
Hum on the highway (No roar)
Balanced out better then normal MTRs and BFGs
Work well in mud/woody trails/sand
Not to much rock crawling here in MI so cant help you there.

So far good experiences with these? Did you opt too get the kedge grip?

My heeps almost done, and i currently have a decently used set of 32X11.5 BFG AT KO's and they really bring the suck in mud and snow. All they do is load up and spin. I was contemplating getting a set of 31X10.5 Guard dogs. My worry is they are in fact retreads.

the max psi means if you put them on a 1 ton truck and tow with them, the max you can run safely is 50psi,

Well I dropped them down to 35 last night...they're not on my rig all the time unless I'm hitting the trails so I guess next time I'll see how they run.

I suppose they'd do better in the snow now!

I didnt get the kedge grip on mine and Im very pleased with them so far. They dont spin at all dry or wet which is surprising to me. The compound they are using is awesome.

I ran the Treadwright guard dogs for a couple years on my XJ -- all around nice tires. How they balance, and their suitability for offroad, depends alot on the carcass you select. Mine were on Bridgestone AT carcasses, and I was always a little nervous about sidewall damage. Treadwright will allow you to select your sidewall provided you are willing to wait until they have them, so if I were to do it again I would specify an MTR sidewall... mine were 285/75/16 flavor and measured 33.2" mounted on 16X8 Toyota LC wheels. I would skip the kedge grip stuff -- mine had the crushed walnut shells in the rubber, and yeah, they gripped the road, and then they stayed there leaving a ton of little holes in the rubber. The holes acted a bit like siping so the grip was still good, but I think it decreased the tread life.

I am now back to old-style MTR's on my WJ (305/70/17), which I previously ran on the XJ, and liked other than their loudness. When these wear out I will like go with a Duratrac or similar, as I DD and put a lot of highway miles on my rig. I usually run 28psi in my 33" tires, and am very happy with the affect on treadlife and ride quality on-road.

it usually runs fine

Ahhh I've been too lazy to chime in, but heres what I've owned.

235/75/15 bfg a/t- ride on road was excellent and wear was minimal over two years maybe 10% loss. Did well in dirt and rocks until they were wet..NOT a good mud capable tire.

33/12.50/15 Dayton Timberlines M/T- Ride was excellent on road and lasted longer than a street tire, but the reason being was hard tread compound so performance was poor offroad. Looks were a plus with this tire as well.

33/12.50/15- Maxxis Bighorn M/T- All around great tire. Wear is low, grip is great and price is low.

35/12.50/15-Mickey Thompson MTZ- Very expensive, wear down pretty fast, noisy on road, but very soft and do very well offroad-Would buy again.

37/13.50/15 SS IROK- Bad Ass in mud,dirt,rocks,reverse,wet hills and actually do pretty well on road as far as wear and stability, I have the radials.

My next set of tires will probably be the new General Grabber if they ever make a 37" tire.

I guess it's my turn.
First I had a set of 235/75R15 BFGoodrich Commercial T/A's. They wore extremely well, and survived a lot of burn outs. They were on the heep when I got the Jeep from my mom. I had a chance to drive on ice/snow in them and they gripped very well and only had about 15% of the tread left. They were very good in sand.
Michelin LTX AT 235/75R15 I got these new off craigslist for 50 bucks since they guy who got them had a set of 31's given to him by his wife. These tires were awesome. They wore great, were very quiet on the highway and stuck like glue in the rain. My only gripe is that they are only made in a 31" max. I loved the way they handled in the sand, rocks, and even the mud(el paso has either thick clay or slippery watery clay/sand). I swear I stopped in th middle of a massive hole and still managed to pull out as if the ground was dry.
Currently im running 3 32x11.5r15 BfGoodrich All Terrains and one 32x11.5R15 BfGoodrich KM2. I had the set but Discount tire had the fourth All terrain on back order since I have real shitty luck with nails. Sand they rock, in the dry rocky dessert they bring the awesome, and in the mud they bring the suck. The KM2, i have in the rear since I'm still 2wd, but I think it might be helping me some. Im able to climb loose rocky hills and lose winding sand climbs as well as guys in their 4wd Jeeps. I like.
Im looking into getting a set of Gaurd Dawgs next, but I rather stay on 32's.

Dunlop Mud Rovers, 30x9.50 worked pretty well, worn very even, and cost is pretty cheap.
Hercules Trail Digger M/T 33x12.50, Worked great, pretty quite,pretty good on rocks and not bad in the mud, worked well in the snow, flaten out really well at 10-12 psi, but VERY soft sidewall, cut 1 on my first run and cut 2 more in the next 2 years, Low cost.
Firestone Destenation M/T, 33x12.50( Actually measure 33") not bad for cost, seem to work pretty well in everything but are as slick as shit on ice, deep tread at start,work better in the mud then my buddy Nitto Mud Grapplers. Very happy so far have plowed them thru lots of shit and rocks and have held up very well, would recomend them to anyone.

They're at 35 psi now...I've never owned a set of mud terrains and most tires that run that load range and a larger size usually take more than 32 psi to properly wear.

I am running Maxxis Bighorn Radial M/T's 265/75/R16. Only a couple of months on these tires so far but I have no regrets with them as of yet. They do ride good and are decently quiet on pavement.

I got the 8ply version so they are a bit heavier than the standard 6ply and just a little more expensive. The 6ply cost $125 each (through my work) and the 8ply were $142 each.

Grip has been very good in the off road situations I have been in since I installed these tires. However, none of those situations have been rock or even mud. Mostly sand and clay.

I initially ran 45psi but that was just way too much. I took some advice from someone else as to that pressure due to me being locked front and rear. I was told that high pressure would decrease tire wear when locked.
That pressure was just too high and I am now at 36psi and the ride is much better. Not sure about that wear issue though.

I was running Goodyear MT/R's and I went through two sets in as many years. They were either way too soft or Aussie lockers do indeed increase wear. I do encounter some scrub when turning slow sharp left turns.

Ok I'll chime in on this one

315/70/15 dunlop mud rover had these on my F150 for over a year and they wore great and cleaned out the florida mud well and had pretty good road manners.

31/10.50/15 Firestone destination A/T I love these tires they do great on the rocks and clay here in NC and are amazing on the road they have amazing wet grip. I have wheel them at about 15 psi and have nicked a side wall so idk just how thick they are but since I DD mine its not a huge deal. They do clean out fairly well and worked great on the florida lime rock and mud.

35/12.50/15 MTR with Kevlar Ill report back in on these here soon.

I'm running Maxxis Bighorns in a 33x12.50R15 and love em. Amazing all around tire. I've been impressed with them on rocks, wet dry or muddy. Very good in sand but not that good in the deep gooey mud. They have very tough sidewalls also.

03-11-2011, 01:25 PM
Iroks-

36X13.5X16, Bias Ply, now on my 2nd set. Pretty happy with them, super tough sidewall, never once got a flat or cut or popped bead. Usually run around 12psi(10 in Moab). Hooks up really well around here(southern Alberta, mud/rock/dirt/loose rock). Works REALLY well in the winter on snowy/icy trails. Street driving not so good, have them bead balanced which worked great on the first set but not as good on the 2nd. I don't street drive it so can't really comment about tread wear, my rear axle is also welded.

37X12.X16(radial) Same tread as the bias so worked about the same tread wise. MUCH lighter tire than the bias and molded better at low pressure. Seemed better on the highway. I didn't keep these tires long, 3rd trip out I cut two sidewalls. Sidewalls were VERY thin, cuts VERY easy on wet sharp rocks and had a stick the size of my wrist poked thru another. Was pretty disappointed, I beat the crap out of the bias way worse than the radials. In the end I sold the radials and bought another set of Bias plys.

Truxus MT

33X12.5X15 Bias ply
I built a rig with my dad and wheeled it while my rig was getting made over. Works very well for around here but never tried it in Moab. Heavy tire with beefy sidewalls, similar to the bias Irok. Was balanced with beads and worked fine on the street. Doesn't see much street use so cann't comment on tread wear. I like to think of them as the street friendly "AT" version of an Irok.

BFG MT

Never had them myself but I know 4 people personally that had them with the "Rim protectors". All 4 sold them after wheeling with them one season after getting contious beads leaks. The "rim protector" bead seems to act as a scoop and force mud/dirt into the bead.

I know this is an old thread but...some info to add

31" BFG AT - Wore well on the street and are quiet. They're all-terrains so sucked in rock and mud. Tended to float too much in deep snow.

:smt07131 Treadwrights MT (the sticky version with beads of cork I think in it) on Goodyear carcass. Gripped well in the rocks but lots of chunking, good in mud and deep snow, screamed like Cessna at 30mph. Worst tire I ever ran on wet pavement and packed snow, no traction what so ever. I got stuck when I stopped on my driveway pulling into the garage. Wore terribly on the road, chunked bad on the rocks, and dryrotted. I got 15K out of them, suppose to be 30k tires. There is a treadwright dealer here in town and he was not happy with them either. But what do you expect for 500 for all four mounted. You get what you pay for.

265/75/R17 BFG KM2 My favorite so far. Pretty quiet an wear well on street, good on wet pavement and snow pack, Stick decent on the rocks, limited chunking and a few gouges and slices out of the sidewalls (pretty good when compared to how beat up the rims are need bigger tires for 17" rims)

37x12.5r17 procomp XTERRAIN RADIAL. they are awesome on the road, in summer winter rain shine.. have so far good tread life. good offroad on dirt and rocks, as long as you are going forward...... these tires absolutely suck going backwards, in snow they will very quickly dig them selfs down as far as possible. that being said, it might be a good thing for mud or sad where there are hard surfaces underneath. just bad in snow backwards.

forwards not many things have stopped me or caused me to not have traction


31x10r15 bfg at k/o awesome all round tire. would put these on anything, great tread life very durable. and perform very well on the rocks around here. i would put these on my car if they came in that size.

edit: i just looked up to see if they have the bfgs to fit a car.... they dont :(

Might as well throw my experience in there, since it was bumped....

BFG M/T's 31x10.5x15" - Great in mud, on mild rock, and decent on the street. Obviously they're pretty noisy on-road, but they got the job done. Put a decent amount of road mileage on them before they needed replacement. I'd buy them again (or a km2) if I had the $$$ and was looking to outfit a 50% street / 50% trail Jeep.

BFG A/T's 31x10.5x15" - No thanks. Everyone has great luck with them, so I gave them a shot. They wore down to ZERO tread in less than two years, less than 15k miles. They were rotated every 3k; they wore evenly, but quickly. They have great on-road characteristics, up until half of the tread's gone, then they start hydroplaning. Obviously they suck in mud, so not very useful down south.

Goodyear Wrangler Duratracs 33x12.5x15" - My current rubber-of-choice. I thought I'd give them a shot since my A/T's brought teh suck. On-road characteristics are similar to the A/T; no road noise, have great handling, and good wet traction (so far). They're also wearing great, so far. Rotated every 3k. Much better than the A/T's in mud, until you get into the thick stuff. I would recommend them if you are looking for an A/T style tire for a lighter, SUV-type DD. Definitely avoid them if you're looking to outfit a heavy truck. The sidewall construction is the same material and ply count regardless of weight range. When I was first looking at these tires, most of the negative reviews are from people who put them on 350's and 3500's and had "squirrely" handling and issues like that.

MultiMile XTX 31" AT's. Fantastic in snow, ice, rain, and sand. Works on slick rock. I keep hearing I should have MT or at least large knobs but when I watch others (with similar setup but MT's) there doesn't seem to be much difference. Maybe if my rear was locked and I was more extreme it would matter. But there was a much greater rockclimbing difference when put the Aussie in the front than when I changed my tires (both pere and post unlocked).
Dead quiet on the road.

Hmmm still cant add picts.

so this is an annuall TOTM thread? ;)

well any way this is my tire story...


31 10.5 15 Kelly safari msr's
good on slick-rock and general wheeling, I got them with less than 1/2 tread so I don't know about ware but that said they where not very good on mud or snow, did good on highway. it took me about a year of dd and wheeling to finish them off.

31 10.5 15 cooper off brand snow's
did good in snow (duh!) not very good for any real wheeling had them for a winter then...

33 12.5 15 pro comp at's
had them for 3 year's and hands down one of the best and truest at's I ever had! used them as dd/off road tires and as my main vehicle that whole time!
the only issue I ever had whit them was the clean-out in mud! but they performed good in ice/snow, sand, slick rock, dusty dirt and most mud situations except for the greasy mine mud ( what I call axle grease)
when I sold them last year they still had 3/4 tread would most defenatly recommend them for anyone that needs a good at!

35 12.50 15 KM2's (current)
dont use them much for dd-ing but so far the best off-road tire I have had! still have yet to test them in mud or snow but so far dang good tires!



my .02 on psi
run them close to the what the vehicle's sticker says then try to match the load rating to the vehicle as well, E- 1/2 to 3/4 ton trucks, D- light duty trucks (rangers, tacoma's etc,) and C- Jeeps and other light suv's!
most zj's, wj's, wk's run best at 35psi as to match the GVWR!

I like my km2's but not great on a thin layer of snow... scared the cap out of my family as I. Lost the back end on a canyon road deciding to spin the zj to the inside of the curve knowing I couldnt correct it...wishing they were siped for icelight snow driving...have some slight chunking from the rocks but holding up well to dd abuse...unlike my treadwright MT's

04-01-2012, 01:07 PM
I like my km2's but not great on a thin layer of snow...my last tire purchase was MTZs vs KM2s - went with MTZs because they are siped. My set is also proving to be a high mileage tire. Not sure what my next set will be, but pricing on MTZs has gone thru the roof since i purchased mine a few years ago.
