I agree with quite a few of the guys. I have the stock size Toyo OC A/T load range E. I really like the tires, but the mileage truly does suck. I may 40,000 out of them if I'm lucky. They only have 25,000 on them now, and they're well more than half worn from the original depth. The Michelins I had on the truck lasted almost 60K. I was going to get them again, but went with the Toyos due to the cost savings. With the treadwear being much higher on the Toyos, the saving wasn't worth it. My next set will more than likely be Michelins again, hopefully larger than stock this time. They do look a little small in the wheel wells.
