My Tundra has Dominator Sport AT tires, and I've put 60,000 miles on them so far (the truck had 45,000 on the odometer at install; an alignment was done at the same time). The BFGs would've lasted longer than 45k, but one tire was slashed by someone / something, and I decided to get a new set ot tires. I like them better than the original BFG Rugged Trails. The Dominators have been rotated and balanced every 5000 miles since new.
When they are rotated, the techs only swap the front and back tires on the same side only (left side tires are always on the left, etc). Anyway, while I was airing them up the other day, I noticed that the right side tires have about 1/8 to 3/16" less tread than the left side tires. The truck drives smooth, but sometimes it feels like it's not "centered" while on the highway; you have to keep a good grip on the wheel and make constant corrections to keep the truck straight. It was like that when I first bought the truck, and it did that after the 45k alignment. I just got used to it. I don't tow much, I don't carry heavy loads, and I don't have a shell on it. Oh, I try to save gas as much as possible, so I don't spin my tires much or race (don't have LSD rear).
Is this right-sided wear pattern due to poor alignment, even though they did an alignment? If it is, is it due to improper toe-in, camber, etc?
