Expert Buying Guide for 2009 GMC Savana 1500 Passenger
For your 2009 GMC Savana 1500 Passenger, the bolt pattern is 6x139.7mm with a center bore of 78.1mm. Aftermarket wheels must have a bore ≥78.1mm; use hub-centric rings (78.1mm ID to 70.3mm or other) to prevent vibration and ensure load is on the hub, not the lug nuts. Offset must stay within 20-30mm to avoid rubbing on suspension or fenders. Lug nuts are 14x1.5 thread pitch; use conical (60-degree) or ball seat nuts matching the wheel's seat type. Never use incorrect seat or thread—this can cause wheel loss. Always torque to manufacturer specs (typically 140 ft-lbs) and re-torque after 50 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 140 ft-lbs after 50 miles of driving to ensure proper seating.
- ✅ When using aftermarket wheels, verify the center bore is at least 78.1mm; use hub-centric rings if larger to avoid vibrations.
- ✅ Check offset carefully: 20-30mm is critical. Going outside this range may cause tire rubbing on the frame or fender, especially with wider tires.
- ⚠️ 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).
