Expert Buying Guide for 1994 Dodge Ram 2500 Regular Cab
The 1994 Dodge Ram 2500 Regular Cab uses an 8x165.1 bolt pattern with a 121.3mm center bore. Aftermarket wheels often have a larger bore (e.g., 125mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is 43mm; deviations beyond ±10mm may cause rubbing or clearance issues. Always use the correct 9/16" lug nuts with the proper thread pitch (likely 9/16-18) and seat type—factory wheels use a cone seat, while aftermarket may require ball or flat seats. Mismatched lug nuts can lead to wheel loss. Re-torque after 50-100 miles of driving.
