In Cayman sizes (roughly 25.5-.6" diameter) there are hardly any tires that fit on the Cayman 17" wheels, 245/45/17 is one and 275/40/17 but the 275 is too wide for the oem wheel and barely anybody makes wider 17" wheels for Porsche fitments unless they are $$$. However plenty of good 18" wheels and lots of tires in those diameters. You could run 225/45/17 and 245/45/17?
On 986 Boxsters i have seen 255/40/17 square and I think 225/45/17 square on Hoosiers or hankook z214
