Expert Buying Guide for 2002 Buick Century
For the 2002 Buick Century, the 5x115 bolt pattern and 70.3mm 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 stock offset is 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut thread pitch: 12x1.5mm. Use conical seat lug nuts (60-degree taper) for aftermarket wheels; ball seat nuts are for factory wheels only. Improper seating can lead to wheel loss. Re-torque after 50-100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 100 ft-lb after 50-100 miles of driving.
- ✅ Avoid using wheels from 2006+ Buick models; they switched to 5x120mm pattern.
- ✅ Check for caliper clearance when using wheels with offset below 40mm.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
