Hello today wanted to mount the winter tires (on steel rims of the old V50) on the new V50 (BJ 2011, summer tires on aluminium rims). Because of the strange wheel nuts at the new V50 (conical course to the thread) I then let it be; was afraid that the steel rims did not fix properly. Do I have to buy a set of new wheel nuts for the steel rims now? Greeting fiete
