Thanks Lyncher for being an ass. You make sense! Anyway, 275s are the limit without adding spacers and rolling fenders out. Very few applications even need 275s. They don't really make sense to me. I can see if you have twin turbo, 4.10s and a 5spd tranny, but if you have a nice HCI stang 275s are a little too much. I have em because the car came with em and have yet to convert. Oh yeah, 275s will also flex and get cut on your fender lips around turns and the inside tire might hit your exhaust around turns depending on sidewall height.
