The lifetime tire deal you have sound like an exclusive program provided by the dealership you bought the car from. I would take a moment and look over the paperwork you got from the dealer on that program or contact your salesperson directly. That's where you'll find the answer!I bought my IS-F with the tire and wheels package my dealership offered here, which gives me free tires lifetime. My car came with bridgestone Potenza tires, but I heard some ISF's come with the Michelin PS2's stock, is that correct? If yes do you think the I can get the PS2's from the dealer next time, and possibly wider tires like some have already put on.(265 or 275 in the back).
