Tire Fit
 

I have a 2003 S - existing tire size is 225/40/18 F and 265/35/18 R.
Are there other size tires / rims I can use? Any suggestions or options I might try?

Lots of threads on tire brand - but I have not seen one on sizes.

(One reason I ask - a friend has an extra set from his Cayman S that he does not need. 235/35/19 and 265/35/19 and I wondered if this was a good option.)
