The hubcaps make a qualitative good impression there are still good but see no aluminum rims from, for winter tires perfectly ok. After unpacking the short instructions (on the box) Read the assembly and the tension ring mounted. There are 3 possible settings, the first I found something too loose matter had then taken equal to the third. The hubcaps can be no problem on the wheels touched down and hold it until now also good. Great value for money!
