Expert Buying Guide for 2008 Dodge Ram 3500 Regular Cab
For your 2008 Dodge Ram 3500 Regular Cab, the bolt pattern is 8x165.1mm, shared with 1994–2010 models. The center bore is 121.3mm—critical for hub-centric fitment. Aftermarket wheels often have a larger bore; use hub-centric rings to prevent vibration and ensure load is on the hub, not lugs. Offset is sensitive: stock is 43mm. Sticking close to this range (40–45mm) avoids rubbing on suspension or fenders. Lug nuts are 9/16" with a cone seat; never use ball-seat lugs. Torque to 140 ft-lbs and re-torque after 50 miles. Avoid wheels with insufficient load rating for this heavy-duty truck.
