Expert Buying Guide for 2020 Chevrolet Impala
For the 2020 Chevrolet Impala, the bolt pattern is 5x120 with a center bore of 66.9mm. When selecting aftermarket wheels, ensure they have a center bore of at least 66.9mm or use hub-centric rings to prevent vibration. The offset should be close to 40mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (14x1.5) and seat type (conical/60-degree). Avoid ball-seat lug nuts as they can loosen. Re-torque after 50-100 miles.
