Expert Buying Guide for 2010 GMC Sierra 3500 HD Extended Cab
For the 2010 GMC Sierra 3500 HD Extended Cab, the bolt pattern is 8x165.1mm with a center bore of 116.7mm. Aftermarket wheels often have a larger center bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset range is 20-40mm; staying within this range avoids rubbing or suspension interference. Always use lug nuts with the correct thread pitch (14x1.5) and seat type (cone or ball seat) to match the wheel. Mixing seat types can cause wheel loosening. Note: 2011+ models use 8x180mm; those wheels will not fit.
