Expert Buying Guide for 2002 Chevrolet Silverado 2500 HD Extended Cab
For your 2002 Chevrolet Silverado 2500 HD Extended Cab, the 8x165.1 bolt pattern is shared with 1999–2011 models. The critical center bore is 116.6mm; aftermarket wheels with larger bores require hub-centric rings to prevent vibration and ensure proper load transfer. Offset is sensitive: stock is 26mm, but aftermarket wheels should stay within ±6mm to avoid rubbing or clearance issues. Always use lug nuts with the correct thread pitch (14x1.5) and seat type (conical/60-degree). Never mix seat types—using ball-seat nuts on conical wheels is dangerous. Re-torque after 50–100 miles.
