Expert Buying Guide for 2015 Ram 3500 Regular Cab
The 2015 Ram 3500 Regular Cab uses an 8x165.1 bolt pattern with a 121.3mm center bore. Aftermarket wheels must be hub-centric; use hub-centric rings if the bore is larger to prevent vibration. Offset is critical: stock is 43mm. Deviating more than ±10mm may cause rubbing or clearance issues with brakes/suspension. Always verify lug nut thread pitch (14x1.5) and seat type (cone or ball). Using incorrect lug nuts can lead to wheel separation. For lifted trucks, ensure wheel backspacing accommodates larger tires. Re-torque lug nuts after 50-100 miles of driving.
