I had the Duratrac's in 315 75 16.
I agree with 06 H3, Great all around tire, but they start to slip. Mine lasted 60k miles, but I ran them another 10k. I never balanced mine, and I rotated them roughly every 10k. They were great in snow and ice, quiet enough, good off-road on the rocks and in the mud. My only complaint is that the rear end got squirrley on loose dirt roads, especially over wash-boards. Drove a friends H3 with the same set up on BFG AT's and it was much better.
I just ordered a set of 315 75 16 Goodyear MTR's. I will have them siped to help with ice traction. I expect them to be on -par with the duratracs in every way, and outperform them on loose dirt roads. The exception is that I dont think that they will last as long, but If I get 40k out of them, I'll be happy....
I think the Duratracs are listed at 19/32" of tread depth, and the MTR's are 21/32" of tread depth. The Duratracs seem to be made out of a little harder compound than the MTR's but I hope it turns out to be a wash, or close to one. Like I said, if I get 35-40k out of them, I'll be happy.
