Correct tire size question

[wrs986]

I appreciate all the information on the tire sizes. I’m the 3rd owner of this car and the previous owner did not put these wheels on the car. When I went to tire rack’s website it has listed for a 2006 PORSCHE CAYMAN S WITH STANDARD BRAKES WITH TPMS
Front: 235/40R18 95W XL
Rear: 265/40R18 101W XL
Same sizes as mine. I know the cayman is the 987 generation but I thought the chassis, wheels etc were similar to the 986.
The tires are 12 years old, I plan to get new ones soon and I wanted to make sure if I decided to get the proper size tires for this car that they would fit on these rims.

Wow! 12 years old! Yikes!

Get 235/40/18 front and 265/35/18 rear.

Want a decent sent of Summer tires without breaking the bank, get these. I run them on my car and love them.

I recently purchased a set of Cayman wheels/tires for my ‘02 base with the same tire set up as the OP.
No issues other than now the speedometer is 3mph slower than actual speed whereas it used to be 5mph slower, and I had to adjust the headlights to compensate for the taller tires in the rear.
