Car still hasn't even gone in for it's first oil change and I have to replace my whole tire for a nail in the sidewall. It hurts my feelers seeing it with the donut on it for a bit. I am debating on picking up a pair of 17" rims with stock tires for the winter anyways and just leaving the 18's in the garage. Later I can swap them with drag radials on at the track anyways. Am I going to experience problems buying factory take off 05-07 17's as far as difference in suspension or the tire pressure alert thing? Btw, ford's price on 18 inch goodyear installed is $187.
