Expert Buying Guide for 2010 GMC Savana 1500 Passenger
For your 2010 GMC Savana 1500 Passenger, the bolt pattern is 6x139.7mm with a critical center bore of 78.1mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset range is tight: 20-30mm. Sticking to this range avoids rubbing on suspension or fenders. Always use the correct lug nuts: 14x1.5 thread pitch with a cone or ball seat matching your wheels. Using wrong seat type can cause wheel loosening. Safety first: verify all specs before installation.
