Expert Buying Guide for 2004 GMC Sierra 2500 HD Regular Cab
For your 2004 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 distribution. Offset must stay within 20-40mm; deviations risk rubbing or bearing damage. Always use 14x1.5 lug nuts with the correct seat (conical/ball) to avoid loosening. Re-torque after 50-100 miles. Wheels from 1999-2010 Sierra 2500 HD fit directly. Avoid 8x180 pattern wheels from later models.
