Expert Buying Guide for 1995 Buick Regal
For your 1995 Buick Regal, the 5x115 bolt pattern and 70.3mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is around 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: the Regal uses M12x1.50 thread pitch with a conical (60-degree) seat. Using incorrect lug nuts (e.g., ball seat) can lead to wheel loosening. Re-torque lug nuts after 50-100 miles of driving to maintain clamping force. Wheels from 1992-2004 Buick Regal models are direct fit.
