My car still has winter tyres on it. Since I need summer tyres and am unsure, I wanted to clarify the following and then buy summer tyres. I own the car for a year and got a complete set for summer and winter. I drove the summer tyres and now the winter tyres are still in use. The tyres have the size (summer and winter tyres) 185/65 R15 88H. In the vehicle license is a different size. me, but the rim size R14. E.g. 185/65 R14 88H. Since there are still wheel caps from original Mazda on it, I wonder if those were from production on. Do I have to stick to the wheel size 1:1?
