Expert Buying Guide for 2012 GMC Savana 1500 Cargo
For your 2012 GMC Savana 1500 Cargo, the bolt pattern is 6x139.7mm with a critical center bore of 78.1mm. Aftermarket wheels often have a larger bore, so hub-centric rings are mandatory to prevent vibration and ensure proper load distribution. Offset must stay within 20-30mm; deviating can cause rubbing or bearing stress. Always use lug nuts with the correct thread pitch (14x1.5) and seat type (cone or ball seat) matching the wheel. Never mix seat types. Re-torque after 50 miles of driving. Wheels from 1996-2014 Savana 1500 are direct fit, but verify offset and bore compatibility.
