Expert Buying Guide for 1994 Buick Skylark
For your 1994 Buick Skylark, the 5x100 bolt pattern and 57.1mm center bore are critical. Aftermarket wheels often have a larger bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lug nuts. Offset is sensitive: the factory 42mm offset is ideal; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.5) and seat type (conical/60-degree for most aftermarket wheels; factory uses ball seat). Improper lug nuts can loosen or damage the wheel. Verify fitment with a test fit before mounting tires.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 100 ft-lbs after 50 miles of driving to ensure proper seating.
- ✅ Avoid using universal fit wheels without hub-centric rings; they can cause steering wheel vibration.
- ✅ Check brake caliper clearance when using wheels with offset less than 38mm, as the Skylark has tight front caliper clearance.
- ⚠️ 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).
