Expert Buying Guide for 2020 Ram ProMaster City
For your 2020 Ram ProMaster City, the 5x98 bolt pattern and 58.1mm center bore are critical. Aftermarket wheels often have a larger bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The offset is sensitive: stock is 30mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use the correct 12x1.25 lug nuts with the proper seat (cone or ball) matching the wheel. Avoid using incorrect thread pitch or seat type, as this can lead to wheel loosening. Re-torque after 50-100 miles. Cross-compatible with 2015-2022 ProMaster City wheels.
