17" vs. 18"
I just measured my '02s rubber from the rim to the road and got 2 3/4" of sidewall. The tires are Continenal Sport Contact 2, 205/50ZR 17" Can any of you tell me the amount of side wall on a Carrera 18" rim? Front wheel measured. I am considering the 18" spoke Carrera type rims but am worried about potholes. If the rubber to the road ratio is about the same, then I have the problem on my 17" that I am trying to avoid. Porsche now has cars new with 19" rims so I don't think it should be too big a problem (until you bury one in a 6" deep pothole, goes for 17 and 18s too I guess). Also is the width of the Carrera spoke wheels different than similar spoke wheels put on at the dealership? I see a lot of 10" wide 18" wheels out there but have heard the Boxster "version" is only 9" wide. Also is the side walls on the 18s stiffer than the 17s? Any thoughts?
