Expert Buying Guide for 2002 GMC Savana 1500 Passenger
For your 2002 GMC Savana 1500 Passenger, the 6x139.7 bolt pattern is shared across 1996–2014 models, offering broad cross-compatibility. The 78.1mm center bore is critical: aftermarket wheels often have larger bores, requiring hub-centric rings to prevent vibrations and ensure load is on the hub, not the lugs. Offset must stay within 20–30mm; deviations risk rubbing on suspension or fenders. Use only 14x1.5 lug nuts with the correct seat—cone or ball seat, depending on your wheels. Never mix seat types; improper seating 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 of driving to account for settling.
- ✅ Verify wheel bore diameter; if larger than 78.1mm, install hub-centric rings to avoid vibrations.
- ✅ Check offset carefully: too low (negative) may rub suspension, too high 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).
