Expert Buying Guide for 2002 Pontiac Bonneville
For your 2002 Pontiac Bonneville, the bolt pattern is 5x115 with a center bore of 70.3mm. Aftermarket wheels often have a larger bore, so hub-centric rings (70.3mm ID to wheel's bore) are essential to prevent vibrations and ensure proper load distribution. The factory offset is 52mm; staying within ±5mm is recommended to avoid rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.5) and seat type—factory wheels use a cone seat, while some aftermarket wheels require ball or flat seats. Mismatched lug nuts can cause wheel separation. Re-torque after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 100 ft-lbs after 50-100 miles of driving to account for settling.
- ✅ If using aftermarket wheels, verify that the wheel's hub bore is at least 70.3mm; use hub-centric rings to center the wheel.
- ✅ Check for clearance between the wheel spokes and brake calipers, especially with lower offset wheels (e.g., 45mm).
- ⚠️ 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).
