I have about 10k on my BFG MT 285/75/17 and there is a lot of "chunking" (chunks missing/flying off the tread) also at this point they are very hard to balance. Twelve ounces on one wheel.

FWIW, I was chunking my 285/70-17 KM2's pretty good, I was only airing down to around 16-18lbs. Some one suggested I go to lower psi, so I started going down to 12, sometimes 10 and the chunking mostly stopped. Only small nicks after that, totally livable. I now have 35" KM2's and haven't chunked them yet. For the sake of the horror story side, I am getting ready to take them in to discount for the 3rd time to rebalance. I've had a vibration around 60-65 mph. They're getting it closer, it's down to a slight vibration as of the 2nd trip. My smaller tires balanced perfect the first time and only needed rebalanced once in 50k miles. I have nothing to add for snow and ice as I live near Phoenix, they do fine in our monsoon rains though. At least in my opinion.

Do you mean lower psi off road to reduce "chunking" or on road?

bthomas

Sorry, I meant off road. On road I kept them around 30psi.

Forgot to mention in my comments above that neither of the two sets of KM2s I had would balance properly. In fact the notoriously hard to balance MTR/Ks were easier to dial in than either set of KM2s. A club member tried a set on his CJ7 and gave up on them after even having a Road Forcce balance done on them failed.

What you asking is really hard to answers because it truly is opinion based. I was SHOCKED on how well these tires handled in adverse weather. But it has been 20 years since I have dealt with mud tires and tires today are much better. I can't see me with any other tire. I run at 32 psi with a 35-12.5- 15 tire. I beat the crap out of them (actually raced them on a paved circle track) with countless off road trips and have only worn away 4/32 of tread in 25k miles. As far as balance mine have not been rebalance since new and never had any problems.

I'm going to give them another chance at it, they may have to make a new commercial for Discount tire after that.. A middle aged bald guy hucking 5 35's through the glass! Actually I hope they can get them right.

Check out the BFg K02 A/T, Put them on my RAM and they have been outstanding

I've had mine for a year and a half and haven't had one issue at all. But I am in southern alabama and don't see much snow. They are great off road and I have spun the tires a bit in wet conditions but nothing crazy. They measured up at 35x12.5 just like they say.

Different people with different stories

I wanted to try the MTR Kevlar in a 35" size and was not sure if I wanted those or 37" tires. So I purchased a set of 35" MTR's online for a super cheap price, the guy needed money and when I got there they were not nearly as close to the amount of tread left he said so I low balled him. He based all tires and value off the tire with the least amount of wear
The MTR's were the worst tire I ever owned, they pulled all over the place and I thought that going to a larger tire that I had something wrong with the front end, because issue magnify when you go to a larger tire. I had the old style MTR on my TJ and I loved them! I think the MTR's were coming apart or something, but have heard from some others that they pull badly. On the other hand something to know is that they are a directional tire so rotating tires is limited!
I found a set of used KM2's from a friend for a good deal so I purchased a new set of all terrains for daily driving and the 37's for off roading.
I will say that the KM2's are sipped in the middle so I have chunking from off roading, but from what I hear that is the only way to run those tires for best traction. Otherwise they are not that good in the snow.
I have driven them in the snow a bit and they are OK, what you would expect form a mud terrain tire that is wide and large lugs.
My .2 cents is if you go with KM2's then sipe them!

Good luck!
