Another vote for the MTRs here. Haven't been stuck with them once and are great on the rocks.

Get the MTR's. Definitely not the swampers you're thinking about in that other thread. The MTR's will be just as good on the rocks and they do very well in mud (that's what I wheel in mainly). And the Kevlar sidewall is very strong. It'll be pretty tough to puncture it on a rock or sharp stick. That was enough reason for me to get them. The awesome traction was a good bonus though

Depends on what type of wheelin' you do. I have DD with MTR's but I am a weekend off-roader. A friend has a CJ-7 with KM2's and he wheels that jeep exclusively. Its not a pavement driver. He really likes the tires which he drives in OK, KS & Mo. 80% and Colorado 20%.

These are going on my DD, and friend of mine is a certified tire dealer, he said he can give me a good deal on a set. I've heard good things about both tires so I sent him both to get quoted. But I'm glad everyone's in favor of the MTR's, they're a little cheaper than the BFG's

I have the BFg km2s I really like them there a little louder then the Kevlar one. my jeep ATM is mostly payment pounder till I get the new axle and lockers but when I took the jeep out it did really well in the mud only time I got stuck was when I hit some nasty mud in a river flooded area my friend has the mtrs the only thing I didn't like about his was the amount of wheel weights on it he got tires and rims together they ended up having wheel weights around about 1/2 of the tire. Mine only has one wheel weight per rim on the same rims he has but you have a hard decision there both great tires

Could you elaborate some more? It's time for me to replace my current KM2's. I'm considering trying out the MTR/K or staying with the KM2's. The biggest feedback I get is that the MTR's have tougher sidewalls but my KM2's have held up fine so far. Thoughts?

I have been running KM2s for about 3 years now, and that is as a trail rig, with occasional pavement driving. I must say i love these tires, they have gotten me through everything (rocks, mud, water crossings) although the side walls do tend to tear a little on rocks. When i move up to 35s ill be going with MTRs just because i have never heard anything bad about them, and that kevlar sidewall will really help out on the rocks.

No complaints with the KM2s, and im anxious to try MTRs when i get new tires.

Mtr's are true to size. Km2's run small. Every run I have been where someone gets a flat they were running km2. Sidewall puncture every time. I have yet to see a flat mtr on the trail.

Bigger, only a couple pounds heavier, tougher sidewalls, quieter, smoother, wear almost as well, better traction on rocks (wet or dry).

That's the only think that makes me nervous about the MTR's, I've heard stories of guys needing unreal amounts of weights on their wheels to balance it out

Both are great tires. You can't go wrong. I prefer the KM2s and have run two sets so far. Not sure what size your looking for but if it's 33x12.5R15 just know that the MT/Rs can only be mounted with the white lettering out in this size.

The MT/Rs can wear differently (even with rotations) because of the tread design and in most cases cause balancing issues. Not a big deal if it's not your DD but something to consider because of the asymmetrical pattern.

As for balancing, I've had an easier time with the MTR's than the KM2's. But I ran my old KM2's on crappy cheap steelies (Cragars) for most of their duration before making the smart switch to aluminum. Those steelies didn't help.

But with 35" and 37" MTR's on 15" and 17" Black Rock 909 wheels, respectively, the balancing has been cake. They don't take much weight and roll smooth at all times. My 37" MTR's are actually the best-riding tire I've ever had on my Jeep. They roll smoother and balanced out easier than my previous 35" MTR's, 35" KM2's and 31" KM1's.

The white lettering isn't available any more.

The asymmetrical tread pattern has nothing to do with abnormal wear or rotations for a DD.

Abnormal wear is due to not keeping them balanced or them being out of round to start with which GY has spent a fair bit of time correcting and so far has done a good job of.

I've heard that too, the tires just aren't round lol, but I'm glad you posted, I'm leaning towards the MTR/K's

Tell your friend to get a new shop to balance his wheels or get them to turn the tire 180 degrees around the wheel. Then watch how the weights are magically no longer needed. I've gotten mine balanced twice and there's no more weights on these 33" MTR/K's than was on any other tire I've run. There's only a balancing problem with the MTR/K's when you have a lazy mechanic or one that never deals with vehicles setup to run offroad.

Agree!!!! I've been a mechanic for 8 years now and finding a good tire man that isn't lazy and just says the h*** with it is hard to find. I've done tires for about two years and if the tire is new and rim is new or fairly you can get them to balance fairly good. As for the tires I've ran both. They both have there pros and cons. I had the mtr/k and though they are puncture resistant and are good on the rocks (aired down to about 17 to 20) They are also E rated. and for a DD is rough on the road. Some will argue but this is opinion based. I now have the KM2's and have put 25k on them now and wheeled pretty hard on them, I love them. They are like cloves when it comes to rocks and off road. I have not been disapointed. They are alot more cumfy on the road and smoother, again IMO. Either way you are going to be satisfied. Hope this helps you. But don't let balancing issued come between you and your purchase.

I wouldn't consider 17-20 psi "aired down."

My 37x12.50x17's are D rated. They ride every bit as well as my older 35x12.50x15's with the correct pressure (~24 psi).

Yep 17-20 psi isn't even close to being aired down, that high of a tire pressure is little better at improving offroad traction than what you get with a street pressure. IMHO, you're not even aired down until you get below 15 psi.

Even a stock size tire can safely air down to below 15 psi, 11-13 psi is very common & safe & is what I ran with smaller tires. That kind of pressure is where you start seeing the significant benefits to airing a tire down for better traction. With my 35's, I regularly wheeled at 7-8 psi without beadlock wheels, & now go below that when necessary since getting beadlocks.

On the BFG KM2 vs. the GY MT/R Kevar, that's like comparing a light hiking boot to a steel toe work boot. The MT/R is nearly bulletproof & can withstand being cut by sharp trail obstacles like sharp rocks far better than the cut-prone BFG MT KM2. Not to mention the MT/R's traction & ability to "hook up" on the trail better is legendary. The BFG MT is an ok trail tire for most uses but it's not the offroad cut-resistant tire the kevlar reinforced MT/R is. I had 3 sets of BFGs (1 AT & 2 MTs) before my MT/Rs & the only BFG I'd ever consider is the BFG Krawler. But I'm now on my third set of MT/Rs over the past ten years & love them, I can't forsee ever switching.

The OP "is" trying to compare the KM2 to the MT/R but he is looking to put these on a DD. The KM2 in this instance is going to be the better choice. No need for any of the advantages of puncture resistance and such on a tire for this type of use.

If you read and talk with lots of folks about both of these tires your going to get the same answers over and over. The MT/R can have balancing issues...then you'll get "take them to a real tire shop". The KM2s suck in the rain...just slow down and be more careful. The MT/Rs are the only real off road tire...really? There are a lot of other options and users that disagree. The MTRs don't wear any different than other tires...many say they do. The KM2s will last longer...zzzzz

For a DD the KM2 is a better choice out of the two. Having said that an MT isn't a good DD tire anywho.

ESP, have you ever personally owned an MT/R?

I'm on my third set of them & they are no more difficult to balance than my old BFG MTs were. And many of us with daily driver or near daily driver TJs have MT/Rs installed, they are not a fast-wearing tire like some other tires are, like the BFG Krawlers for example.

Few in this forum don't drive their TJs on a daily or near-daily basis.

Hi Jerry,

It sounds like your pretty sold on the MT/Rs. Nothing wrong with liking a particular tire and praising it. No I have not owned a set of MT/Rs personally. I've have owned KM2s, BFG ATs, Duratracs, and Mickey Thompson MTZs. I almost picked up a set of MT/Rs when I got my second set of KM2s for the 2013 JK we just received. I would like to run them so that I could have some more experience with them.

I only have seen them on many of the jeeps we wheel with. Some are worn down on the smaller lug tread size disproportionally to the outer lugs. I've seen this over the years from other rigs and it's one of the concerns I've had with putting them on my Jeep. I've read about this across the boards too with others so it's not only my experience with them. I have also seen MT/R sets on various rigs that are nearly bald evenly all over showing good wear. It's a wash really to say they all wear badly but it's also incorrect to say that people just don't have these real experiences with them. I like to offer that both exist.

Additionally, there are better tires for a DD than a tire that is marketed as the strongest off road tire out there. I've run MTs on my DD for years too but I'd surely get better wear and mpg from a non MT as mentioned.

Yeah I know that and I'm running a set of damn good AT's at the moment haha, I haven't looked at the make honestly, but I'm set on upgrading to MT's, so I can get stuck lol

just look at the tread pattern on an MTR, nice open outer lugs to throw mud and the street/rain friendly inner tread with good siping. for how aggressive they look they are quite on the street. this is my third set of MTR's as well (first set of the newer Kevlars). my last set of 37's were mounted on beadlocks and I would run 8-12 psi - worked great. my new set are on non-beadlock aluminum rims and I've only gone down to 20 psi so far and they've worked great. haven't done any crazy tire smokin' obstacle climbs yet but I've done several waterfalls, staircases, ledges and they've been great. as far as balancing, mine are about a year and a half old with about 5k miles on them (not really a DD but 80% street) and they are super smooth/vibration free. there is a fair amount of weight on each for balance - maybe 12 oz worst case (37x12.50/17's). personally - I always sell my tires when they get to 50% and the MTR's have worn great. I have heard some say they get hard to balance and start to wear uneven when approaching the end of their useful life.

I think it was last year when FourWheeler? did an M/T comparison and the KM2's didn't fare well. A Cooper or Hankook took top honors and the MTR's were 2nd or 3rd. I think BFG got caught sleeping while several tire MFGr's were burning the midnight oil and designing better offroad tires. .02

You can safely take those 37" MT/Rs down to below 10 psi without beadlock wheels, so long as they're not an extra-wide wheel like a 15x10. I ran my 35" MT/R for years at 7.5-8psi with non-beadlocked 15x8 wheels with them never unseating on even very tough offcamber treails. Even with a 15x10 I wouldn't hesitate to take them to 9-10 psi on on a non-beadlock wheel.

With beadlocks, you can take them down to whatever you want, certainly even 3-4 psi without worry. I run my 35" MT/Rs at 5-6 psi all the time on my beadlocks.
