I need some help and advice regarding winter tires on my Audi S4. I bought a snowtire and wheel package from my Audi dealer for my 2001 S4. The wheels are 16" Mille Miglia Spiders. Tofday, when I was putting them on my car, I noticed that the center hole in the wheel does not fit the center flange on the barkes (not hub-centric). I am concerned that the lug bolts are bearing the weigh of the car, and could fail. Are there adapters for these wheels to mate them properly to the brake flanges?
Also, are the factory lug bolts recommended for these wheels? It didn't feel like I was geting much engagement of the threads when I put them on. I would appreciate your hwelp ASAP.
