Expert Buying Guide for 2009 Chevrolet Impala
For your 2009 Chevrolet Impala, the bolt pattern is 5x115 with a center bore of 70.3mm. When selecting aftermarket wheels, ensure they have a center bore of at least 70.3mm; if larger, use hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is 44mm; wheels with offsets between 38-50mm typically fit, but deviations may cause rubbing or clearance issues. Always verify lug nut compatibility: the thread pitch is 12x1.50, and the seating type must match—factory uses cone seat. Using incorrect lug nuts can lead to wheel detachment. Re-torque after 50-100 miles of driving.
