Expert Buying Guide for 2008 Cadillac XLR
For your 2008 Cadillac XLR, the bolt pattern is 5x120.65mm with a center bore of 70.3mm. When selecting aftermarket wheels, hub-centric rings are mandatory to ensure the wheel is centered on the hub, preventing vibrations and stress on lug nuts. The factory offset is 61mm; deviations beyond ±5mm may cause rubbing or clearance issues with suspension and brakes. Always use lug nuts with the correct thread pitch (12x1.50) and seat type—factory wheels use a cone seat, while aftermarket wheels may require ball or flat seats. Mismatched lug nuts can lead to wheel loosening. Verify all specifications before installation.
