Anybody have these on there truck? I was trying to read tireracks reviews and seem to be getting mixed opinions of the tires, some say about 20,000 mile life, others are saying they do donuts and get 30,000+ and one guy even said they were bald after 9,000 miles. I found a pretty good deal on these and am ready to order my wheels and tires, just wanted to see if anybody has/had these on there truck and their opinion and aproximate wear of the tire. Thanks.
