Expert Buying Guide for 1994 Buick Century
For your 1994 Buick Century, the 5x115 bolt pattern is shared with 1992–2005 models, ensuring cross-compatibility. The 70.3mm center bore is critical: aftermarket wheels often have larger bores, requiring hub-centric rings to prevent vibration and ensure proper load distribution. Offset is sensitive; the factory 45mm offset maintains correct scrub radius and suspension geometry. Deviating more than ±5mm may cause rubbing or handling issues. Always use lug nuts with the correct thread pitch (12x1.50) and seat type (cone seat for most aftermarket wheels; verify). Improper lug nuts can lead to wheel loosening. Re-torque after 50-100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 100 ft-lbs after 50-100 miles of driving.
- ✅ If using aftermarket wheels, ensure hub-centric rings match the 70.3mm bore to avoid vibrations.
- ✅ Check offset carefully: staying within 40-50mm prevents fender rubbing and maintains steering feel.
- ⚠️ 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).
