Alright, i got some new bullit style rims, 17" for my v6, and i had those pirelli tires put on that they use on the GT's, 235/55/17. The second i pull out of ford and get up to speed, my steering wheel starts shaking left to right, at about 50mph. I take it back to them and one of the guys there tells me its because they're are wider tires and that i'm just feeling the road more. He also says that my car was tuned for the stock tires, is he b.s.-ing me or no?
