Expert Buying Guide for 1997 GMC Savana 2500 Passenger
When selecting wheels for your 1997 GMC Savana 2500 Passenger, the 8x165.1 bolt pattern is shared with 1996–2010 models, but the 116.7mm center bore is critical. Aftermarket wheels often have a larger bore; use hub-centric rings to prevent vibration and ensure proper load distribution. The factory offset is 28mm; deviations beyond ±10mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (14x1.5) and seating type—factory uses cone seats. Using incorrect lug nuts can lead to wheel loss. For safety, re-torque after 50 miles and periodically thereafter.
