The problem is that the Boxster is supposed to wear 255/40/17 and not 245/40/17. You think I’ll have an issue if I use the later one?


Thanks
Need more info:
Which tires exactly are on the car now vs the 245s? Are they compatible in grip and handling? How old are the spare tires?

Which year and model of car exactly? A 986 can wear pretty much any tire but a 987 gets finicky if you change sizes.

Does it matter to you if the car has significantly different handling with unmatched tires?
