The proper winter wheel set for the turbo/gt3 at least has a slightly narrower rear wheel.

I know that but apparently Porsche "allows" this combo as well. I haven't noticed any weird driving behavior but I want to make sure this combo is OK (for legal reasons and because I want to be on the safe side, ESP and all).

According to my Porsche dealer the combo is not allowed by Porsche and is hence not road legal in CH. It would surprise me if it is any different in D.

I have been looking at winter tires for my GTS and I have been told to not put 295 winter rubber on the 20 inch summer rims. You need the 20 inch winter rims. 19 inch won’t fit due to RWS.

If you have official written confirmation please PM me.
