Expert Buying Guide for 2001 GMC Savana 2500 Passenger
For your 2001 GMC Savana 2500 Passenger, the bolt pattern is 8x165.1mm with a critical center bore of 116.7mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibrations and ensure proper load distribution. The offset is sensitive; the factory spec is 28mm, but a range of 20-35mm is acceptable. Exceeding this can cause rubbing or bearing stress. Always use lug nuts with the correct thread pitch (14x1.5) and seat type—factory wheels use a conical seat, while aftermarket may require ball or acorn seats. Never mix seat types. Re-torque after 50-100 miles. Wheels from 1996-2010 Savana 2500 models are direct fit.
