Expert Buying Guide for 2009 Dodge Ram 3500 Regular Cab
For your 2009 Dodge Ram 3500 Regular Cab, the 8x165.1 bolt pattern is shared with 1994-2010 models, but aftermarket wheels require hub-centric rings (center bore 121.3mm) to prevent vibration. Offset is critical: stock is 43mm; deviations affect scrub radius and load capacity. Always use 9/16" lug nuts with correct thread pitch (likely 9/16-18) and proper seat type (flat or conical). Mismatched seats cause wheel loosening. Verify load rating exceeds 3,500 lbs per wheel. Re-torque after 50 miles.
