I have an imported vehicle with 235/65R17 tyres on 17×6.5JJ rims. On the rims are still all-year tires, which I definitely want to replace through winter tires. I wanted to raise the all-year tires in the following summers until they left, and then switch to summer tires. Since I have only one set of rims, I would like to know from the community whether it is generally bad for the tires if they are always on and off again. It is advisable to buy a second set of rims, so that when changing winter/summer or summer/winter, only the wheels have to be replaced? If you generally have no concerns to keep removing the tyres from the rims, I prefer to stay with a set of rims. By the way, they are stink normal tires, not runflats or something like that. The original rims are not available in Germany.
