Expert Buying Guide for 2020 Ram 2500 Crew Cab
For your 2020 Ram 2500 Crew Cab, the 8x165.1 bolt pattern and 121.3mm center bore are critical. Aftermarket wheels often have a larger bore; use hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is 43mm; deviations affect scrub radius and clearance. Stay within ±6mm to avoid rubbing or bearing stress. Always match the 14x1.5 thread pitch and use conical (60-degree) seat lug nuts. Never use ball-seat or shank-style nuts—they can loosen or damage the wheel. Re-torque after 50-100 miles. This generation (2011-2024) shares fitment, so wheels from those years are direct swaps.
