Ok, debating on these two tires, and which I should choose. I'm running 35 12.5x15. Don't really do much mudding, I stick to trails, and crawling and at tires just aren't cutting it. (Plus they're pretty dry rotted). I heard the km2's have a new, upgraded sidewall but how do they compare to the Kevlar sidewalls? And how's the traction in slippery terrain, loose gravel etc. I live in mountains and it often gets pretty slippery climbing up the side of one, so from your experiences, which has more bite?
I have KM2s. Excellent traction all around. They are great for rock crawling but also good in loose sand. Noisy- but that's a MTR for you. I have 305/70/17s with an E sidewall. My buddy's KM2s in a 35 have a C or D rating. It could be the shocks- but his ride is softer on pavement. I do wheel with a bunch of people with MTRs - also good. For each tire check actual dimensions- a 35" tire is not the same across the board. KM2s run a little narrow- don't know about MTRs.
Tire rack has a great side by side comparison for all tires. It said the km2's were better in just about everything, but it doesn't compare the sidewalls. Ill be getting a set soon, i might just flip a coin...
One thing to consider when comparing these 2 tires is size. The MTR is going to be substantially larger than the KM2. That was one of the factors in my decision to go with MTR's.
Also, I have to say I don't give the reviews on Tirerack or Discount Tire much credence. My preferred method for selecting tires, etc. is through observation. I study experienced off-roaders in similar vehicles who run in similar conditions... and who have the bank to run what they want. I do NOT have that kind of bank, so I really try to make the right choice the first time. Given that my priority is rocks (I hate mud), there was one overwhelming choice. MTR-K's.
I have the KM2's and i am really pleased with them. They are wearing well and are very quiet. They have great traction on and off road. The ride is very comfortable. I think the sidewall is pretty strong, i haven't had any problems yet. I have had a couple oh crap moments with rocks. They also look cool on the jeep. They handle great in rain and on ice and in wet snow. In powder snow it tends to pack in between the treads. No big deal though. I love them and am very happy with them.

Both tires are very good. MTRs will be better on the rocks. If your not hardcore, go with the KM2s. Not that they aren't hardcore, but they are better all around including on the road than the MTRs, IMO.

Had my KM's for 35,000 now. Great tire and could probably go for another 10,000 or so. Great in sand and trails. Never had any experience crawling, but they hydroplane REALLY, REALLY bad. So if it rains a lot, don't get them
Loved the KM2s when I had them before. Will be getting them again soon. The MT/Rs are a great off road only tire too. They will have better sidewall protection but many have attested to them wearing un-evenly on here and on other boards. Could be that they were not properly rotated but with so many stating this, it probably is true to some degree.

MTRs are nice but stiffer-feeling and a bit buzzier. The KMs I had were great offroad and had a soft ride, but the MTRs do better on snow and water. I like both but you will be happy with the MTRs. Do rotate that and cross-rotate them- frequently, or you will mess them up fast.

Keep in mind that with the anonymous nature of reviews posted on sites like tirerack and discounttire, essentially anyone could post. Even the manufacturer themselves...to push their own products or even rag on their competitors.
In this site's review, the Goodyear tire is superior, when considering all around performance. 4+ stars in all categories of terrain.
As has been said before, beauty is in the eye of the beholder, and tire performance is too. After much listening and reading reviews, I am currently leaning to the GY Maxim Traction/ Reinforced with Kevlar.
