I run them and so far I love them. I only have 5000km on them but so far I am impressed. I have a 2000 Jeep Cherokee. The tire size is a P235/75/15. I had to replace the first set due to vibration. My new set is fine. These tires are the best AT tire I have ever owned. They are quiet, ride good, handle good, and traction is extreme! I have tried them in most conditions and they work excellent for an AT tire. I was in about 4 inches of slick mud and just walked right through it in two wheel drive. I have owned Cooper At's, BFG At's, UniroyalAWT, and Goodyear RTS. These are the best I have owned! Now as far as mileage I can't comment. For the price, I wouldn't hesitate. You won't be dissapointed.
