Cayman 18" on my 986 - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I'm thinking about buying the Cayman 18" wheels from wheelsandcaps.
Does anyone know what tire size I should run front and back?
These will be going on my 2003 986.

Any feedback would be great.

Tire sizes for 18s on a 986 are:

F 225 / 40 ZR
R 265 / 35 ZR

Many of us run 235/40 on the front and 275/35 on the rear...a few 285/30, as well.

I have 8" and 10" x 18s on my '02 S running the combination above without issue.

Might not want to get too wild with oversized tires as those Cayman wheels are only 8 and 9 inches wide.
