Searching for info on winter fitments (Canada) for 718 Cayman S. Found two OEM on Porsche site: Front - 8J 18 RO 57 235/45 / Rear 9.5J 18 RO 49 265/45 265/45 and: Front 8J 19 RO 57 235/40 / Rear 10J 19 RO 45 265/40. Cheers
For the Porsche Cayman, it appears that you show only one wheel width. I would assume the F and R use different widths.
You should press + to see rear wheel spec.
...not sure on what’s the best / biggest / widest / maximum tires or rims will fit your car?
