If anyone can assist. I have a 2021 Cayenne GTS coming in and was wondering if there are a set of snow tires that will fit 21X9.5 FA, 21X11 RA. Stock tire size is 285/40/21 and 315/35/21. I think the problem is the rear size. Any help would be great.
Check tirerack.com. They recommend 275/40 and 305/35. I think this is also what Porsche uses in the winter wheel and tire sets. The folks at tire rack are very helpful and should be able to tell you if these tires will fit on your wheels, and have rolling diameters that are similar to your stock tires.
Please let me know what you decide, as I am in Colorado and considering buying a GTS Coupe.
