Well I would have loved to post my experience with the km2's on a trail but instead I only have new experience with them on the back of a hauler. I believe one of the timing chains broke on my way to Hump and Bump. Heard a bang followed by clacking. No smoke or fluids. Engine wanted to start again but was only firing occasionally. Not pleased with the Pentastar at the moment.
They gripped the flatbed nicely though no slippage at all. The sidewalls held up for the entire 19 miles.

The facts are Four equally built, almost indentically set up jeeps tackle the same trails over a weekend worth of wheeling. The only real difference was the tires the rigs were running, two had Toyo's, one had Nitto's, and mine ran MTR/K's. I was the only one with one flat tire and two other tires bad enough to need immediate replacement, the other three jeeps had tires that were unaffected. The other item of interest is that two of the other rigs had run MTR/K's in the past and both had the same issues with the Goodyears. As for knowing what I am doing, well after 30 years of wheeling I am still learning everytime I go hit the trails, but I am not known for being an amateur or only taking easy lines. I do push equipment pretty hard. Video and photo evidence below, I am in the black jeep.

My friends that do hardcore wheeling have also had crappy luck with the Goodyear MTs with Kevlar. I, however, have has great success with these tires in light/moderate wheeling. I do some rocks, but about 70% of my off road time is in soft sand or wadis. The MTs work great in this realm when aired down. Maybe I'm lucky, but they haven't stranded me yet. They are also quiet on-road.... Where I do 80% of my driving.

The Goodyear MTR's w/Kevlar are a great all around tire, except for icy snow. Under those conditions they are dangerous and break loose unexpectedly, and abruptly. They are great in snow, dirt, mud, pretty good in sand, and excellent on road. They are very quiet for as aggressive as they are. Not much experience in rocks with them as they were on a Ford F350. They are light however, a 37X12.50-17 weighs in at between 73 and 75 lbs, whereas a 35X12.50-17 Pitbull Rocker Radial, is somewhere in the 85lbs range. Personally I like the Pitbulls but since I am stuck with the Dana 30 (for God knows how long), and I want 37's I will be going as light as possible. I am not a "hardcore" wheeeler nor will be until my Wrangler is paid off. I would just say, LISTEN to these guys, there is a ton of experience on this forum, and to "those guys" I would say, cut some slack here not everyone is, or wishes to be a "hardcore" wheeler.
