dumb "wheels & tires 101" question - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I just went with the Porsche factory recommendation for 18" wheels.

225/40/18 front

265/35/18 rear

I went with 245's in the rear on my 18x9 Carrera 5 spokes. (225 up front).

The tech over at Frisby Race Tire felt the 265 would have been too much for track and Autocross. Being that they sell allot of race tires like Hoosiers and Kuhmo Victoracers I went along with his recommendation.

Ditto to the sizes Thumper mentioned.
Not an autocrosser, so overtire-ing the car is not a issue with me.
From the back, it looks like the car is mostly tires and exhaust pipe.

What year is your Box'? Apparently, '97s don't take well to 18" rims. Search the board, but I remember a recent thread in this forum detailing the problem. If your car is not a '97, fogetaboutit, it doesn't apply to you.
