Is anybody having trouble with the stock BFG sidewalls? I have a little less than 30k miles on mine and the passenger sides have checked quite a bit. I even have some chunks out that leave white exposed. It looks like rub from curbs. The drivers side haven't done it and I have only rotated front to back. I had planned on changing them out next fall, but might have to spend the money sooner. I've been running 58psi front and 55psi rear.
