Expert Buying Guide for 2008 Audi A8
The 2008 Audi A8 uses a 5x112 bolt pattern with a 57.1mm center bore. When selecting aftermarket wheels, ensure hub-centric rings are used to match the exact bore, preventing vibrations and ensuring proper load distribution. The factory offset is 42mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: the A8 requires 14x1.50 ball-seat lug nuts. Using incorrect thread pitch or seat type can lead to wheel loosening. For optimal safety, re-torque lug nuts after 50-100 miles of driving.
