Expert Buying Guide for 1994 Buick Park Avenue
For your 1994 Buick Park Avenue, 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. Offset should stay near 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.50) and seat type—factory wheels use a conical (60-degree) seat, while aftermarket wheels may require ball-seat or shank-style nuts. Never mix seat types; improper lug nut engagement can lead to wheel loss. Re-torque after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 100 ft-lbs after 50-100 miles, then periodically check.
- ✅ Avoid using wheels with a center bore larger than 70.3mm without hub-centric rings.
- ✅ Verify offset with a test fit; aftermarket wheels with offset below 40mm may contact the strut.
- ⚠️ 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).
