hey, I got a 08 c300 and when I bought the car it came with TSW rims, so today I took the car to the tire shop to get new tires and the guy told me the rims do not have hub rings, so can someone please help and and tell me what size rings I should get, thanks

 

Your benz is 66.6 tsw is between 72 to 76mm unless its mandrus by tsw then they are hub centric..

Tsw uses special hubrings that are not that high like other ones and also dont have the edge around them, so make sure the rings you get actually fit your wheels.. Ive seen a lot of ppl mount wrong rings in tsw wheels
