I am two weeks away from receiving a 6MT, black on black, premium, aero package, coupe and suddenly became concerned about everything I was reading about the 18" summer tires for bad weather (i.e. snow). To remedy this, I was considering either waiting for the 04 model which I understand has an option for 17" all season tires OR asking the dealer to make the swap in the car coming in. Am I making a mistake? I am trying to avoid the hassle of having to switch out tires in the winter (a major hassle due to space issues) and the extra expense. All input is appreciated. Thanks.
