Cayman S wheels - what tire size to use (Boxster or Cayman)

[sfoster13]

This is probably a very stupid question, but I have a set of 18" Cayman S wheels that I bought to use in the summer. I need to buy a set of summer tires for them.

Car is a 2002 986 S

Cayman S wheels
8" 57mm ET Front
9" 43mm ET Rear

OEM size for 18's on the 986 is 225/40/18 and 265/35/18

OEM size for 18's on the Cayman S is 235/40/18 and 265/40/18

Realize there isn't much difference here in size but should I stick with the 986 sizing?

Stick with the 986 specs.
