Expert Buying Guide for 2006 GMC Savana 1500 Passenger
For your 2006 GMC Savana 1500 Passenger, the bolt pattern is 6x139.7mm with a critical center bore of 78.1mm. Aftermarket wheels often have a larger bore, so hub-centric rings are mandatory to prevent vibration and ensure proper load distribution. Offset must stay within 20-30mm; deviations risk rubbing on suspension or fenders. Use only 14x1.5 lug nuts with the correct seat type—cone or ball seat—matching your wheels. Never mix seat types; improper engagement can cause wheel loss. Always torque to manufacturer specs and re-torque after 50-100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles to account for settling.
- ✅ Verify wheel bore is 78.1mm or use hub-centric rings; avoid lug-centric mounting.
- ✅ Check offset carefully: too low (under 20mm) may rub suspension; too high (over 30mm) may contact fenders.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).
