I've had the KM2's for about a year now. I will say that they are very good on the street and offroad, but the sidewalls are cut very easily. I had a friends go through 3 tires in Las Cruces last year. If you 're going to be in very sharp shell type rock then you better have a lot of plugs with you.

I guess I may as well chime in too since I've had 35x12.50-R17 KM2's on my Jeep since it had 300 miles on it (April, 2008). They seem to be wearing pretty good for how soft they are. I also had them siped which I would recommend everyone do that as well. Over the years I've noticed a major, and I mean major improvement in traction in almost all conditions with siped tires. Additionally, I have not experienced much "chunking" either (I'm not sure what anyone else calls this, but I've always referred to it as chunking when chunks of the tire are broken off because they are siped).

So far, I have had to replace only one, but I always get my tires from Discount and I always buy the insurance for them, so it didn't cost me any extra for the replacement. If memory serves, the sidewall was slashed by a rock up in AFC shortly after I got them. Although the tire never went flat, I showed the tire to Discount and made my case, and they went ahead and replaced it. I was lucky in that this happened within a few hundred miles so the new tire wasn't any bigger than the used ones.

I've also been quite a few places in various weather/trail conditions and I think the tires have performed very well. During our trip last August, it snowed our second night out. I will say the trail we were on was pretty rough for the last 13 miles with some very steep, rocky sections. Even with the light snow on the ground and pulling a heavily loaded trailer, I really didn't slip a tire. I had all four tires down to 12 psi.

There was also a spot a few days later where we had a very long, steep uphill climb. Because of the heavy shade it was an absolute quagmire, with mud 9"-12" deep. Even pulling that trailer, I was able to make the climb without having to stop even once. I just kept steady pressure on the throttle and up I went; albeit at a very slow pace.

I've also been up Providence Canyon quite a few times; every time without my trailer. Except for this last time, I haven't had any problems at all. However, I should mention the lack of traction I had going up Providence Canyon a few weeks ago. I will say that there was quite a bit of snow up there, and the ground was pretty much frozen solid. And except for Doug, who was the first vehicle and had virgin snow to climb on, every other vehicle had problems getting up that hill that day. I'm going to go out on a limb and say that anybody, regardless of tire is going to have a difficult time trying to climb ice.

Finally, judging by the number of miles I've driven and the amount of tire tread remaining, I'm guessing I'll get around 25,000 - 30,000 miles on the set of five tires; I rotate in the spare regularly.

Hope that helps.

Has anybody got these new tread design BFGoodrich Mud Terrain KM2? I currently have BFG Mud terrain KM (old tread design) that are less than 3 years old and have only 3600 miles on them and they are cracking (dry rotting excessively) and BFG is going to warranty them. They say they can't get the old tread design any more, but will get me a set of the new ones. I'm just wondering if anybody is using them. They look simular the Krawler. Any info would be welcome. :think:

There awsome my brother has a set he loves them. there very affordable for 35s too.
