Hello. Slowly this gets really difficult. I will soon get my new car. This has 17 inch original aluminium rims in summer. For winter it gets 15 inch steel rims with winter tires. Now I wanted to buy wheel screws for the steel rims. The steel rim is according to the manufacturer’s specification (hole circle, ET etc.) Have bought the wheel screws lt picture. So cones. Now I read that the rims are not suitable for ball-rings. And these are steel rims? Well the question is whether the original rims are Then at least the new wheel screws can be taken and the new ones in the summer then? Only my car no longer has an emergency bike but such a vulcanization device. What should I do now?
