Expert Buying Guide for 2002 GMC Sierra 2500 HD Regular Cab
For your 2002 GMC Sierra 2500 HD Regular Cab, the 8x165.1 bolt pattern and 116.7mm center bore are critical. Aftermarket wheels often have a larger bore; use hub-centric rings to prevent vibration and ensure proper load transfer. Offset must stay within 20-40mm; deviations risk rubbing or bearing stress. Always use 14x1.5 lug nuts with the correct seat—factory is cone seat. Never mix seat types; improper seating can cause wheel loss. Verify wheel load rating exceeds your truck's GVWR. Wheels from 1999-2010 Sierra 2500 HD are direct fit.
