Expert Buying Guide for 2004 Buick Century
For your 2004 Buick Century, the 5x115 bolt pattern is shared with 1992–2005 models, ensuring cross-compatibility. However, the 70.3mm center bore is critical: aftermarket wheels often have a larger bore (73.1mm common), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The 45mm offset is sensitive; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (12x1.50) and seat type—use conical (60-degree) seat lug nuts for aftermarket wheels, never ball seat. Improper lug nuts can lead to wheel loosening. Safety first: consult a professional if unsure.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using universal fit wheels without hub-centric rings; they can cause vibration and stress on wheel studs.
- ✅ Check brake caliper clearance when changing offset; even 5mm difference can cause rubbing on this model.
- ⚠️ 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).
