Expert Buying Guide for 2009 Chevrolet Silverado 3500 HD Extended Cab
For your 2009 Chevrolet Silverado 3500 HD Extended Cab, the critical fitment specs are: bolt pattern 8x165.1mm, center bore 116.6mm, offset 12mm, and lug nut size N 14x1.50. The center bore is hub-centric; aftermarket wheels with a larger bore require hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive—staying within ±12mm of stock maintains proper scrub radius and clearance. Always use lug nuts with the correct thread pitch (14x1.50) and seat type (conical/ball seat as per wheel manufacturer). Mixing seat types can cause wheel loosening. Wheels from 2007–2011 Silverado 3500 HD are direct fit.
