picking up my 335xi coupe on saturday. I got it with the 18in wheels w/ rft's. They are offering my wheel/tire insurance for $795 which covers up to $5,000 worth of damage. I drive to and from Manhattan, pot hole galore, everyday but its mostly highway driving. I've never (knock on wood) had a problem in the past with my old bimmer and also my STI. What do you guys think? Do these RFT's blow out easily?
