Expert Buying Guide for 1994 Chevrolet G-Series G30
For your 1994 Chevrolet G-Series G30, the critical center bore is 116.7mm. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset range is tight: 0-15mm. Exceeding this can cause tire rubbing on suspension or bodywork. Always use the correct 9/16" lug nuts with the proper thread pitch (likely 9/16-18). Verify the seating type—factory wheels use a conical (60-degree) seat. Using incorrect lug nuts can lead to wheel loosening. Stick to 1992-1996 G30 wheels for guaranteed fitment.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to maintain clamping force.
- ✅ Inspect hub bore clearance: if aftermarket wheels have a bore larger than 116.7mm, install hub-centric rings.
- ✅ Avoid wheels with offset outside 0-15mm; test fitment with a spacer if needed to clear brakes or suspension.
- ⚠️ Torque lugs in a star pattern to 140 ft-lbs (190 Nm), then re-check torque after 50-100 km (30-60 miles).
