Expert Buying Guide for 1997 Oldsmobile Bravada
For your 1997 Oldsmobile Bravada, the bolt pattern is 5x120.65mm with a center bore of 70.3mm. When selecting aftermarket wheels, ensure they have a center bore of at least 70.3mm or use hub-centric rings to prevent vibration and ensure proper load distribution. The factory offset is 12mm; deviations beyond ±5mm may cause rubbing or clearance issues.
