After arguing with the dealer for hours over the condition of my rear tires the service rep finally tells me to look at the very inner edge of the rears. Sure enough theres a pinstripe thats worn down to the steel bands. Why he couldn't point that out to me to begin with eludes me but thats another story. Looking at my X from the rear they are obviously tilted in at the top. I am planning on replacing the rear control arms and having it realigned. Im going to have to replace the tires also but want to avoid having this happen again cause I dont ruin another set. 20in tires are cheap. What advice you guys to avoid this.
