rear tire size on OEM 18" wheels for a 968
Gentlepeople,
I recently purchased a set of '94 3pc Porsche OEM C2 turbo wheels ("Speedline for Porsche" as the script says) - same wheels as on the Turbo S.
Fronts 8" - I will mount 235/40 as specified for the Turbo S
Rears 10" offset 61mm - 265/35 are specified however, I've seen this size tire mounted on 10" rims and they look excessively stretched. Has any on tried 275/35? Were the fender lips rolled?
The car will not be tracked but will be lowered 1".
Your advice would be appreciated!..Thanks..Petko

From what I've been told, you can run a 285 on the back before you start to experience any rubbing. I would go with a 275 though, just to be on the safe side. Go to <a href="http://www.968.net" target="_blank">www.968.net</a> and see who is running the biggest tire.

Three Wheelin'
I'm using 8" X 18" and 10" X 18" hollow spoke rims.
I have them mounted with Kumho Ecsta V700's for the track...225/40/18 up front and 265/35/18 in the rear.
With very little negative camber up front, the 225's look like a pretty tight fit. I imagine if I add some more camber that 235's would not pose any problem.
The rear 265's appear to have plenty of room, and one could certainly put more rubber back there.
But, I wouldn't do that until the fronts could be done at the same time. Otherwise the car will understeer/push too much...more grip in the rear and not enough up front; watch out fella's!
