Expert Buying Guide for 1996 GMC 1500 Regular Cab
For your 1996 GMC 1500 Regular Cab, the 6x139.7 bolt pattern and 78.1mm center bore are critical. Aftermarket wheels often have a larger center bore, requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lug nuts. Offset must stay within 20-30mm; deviations can cause rubbing or poor handling. Always use lug nuts with the correct 14x1.5 thread pitch and proper seat type (cone or ball) to avoid loosening. Failure to match these specs compromises safety.
