Expert Buying Guide for 1998 GMC Savana 3500 Passenger
For your 1998 GMC Savana 3500 Passenger, the 8x165.1 bolt pattern is shared with 1996–2010 models, but the 116.7mm center bore is critical. Aftermarket wheels often have a larger bore; use hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive: stock is 28mm. Deviating more than ±10mm may cause rubbing or clearance issues. Always verify lug nut thread pitch (14x1.5) and seat type—use cone-seat nuts for aftermarket wheels; ball-seat can cause loosening. Safety first: improper fitment can lead to wheel separation.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles to 140 ft-lbs; check again at 500 miles.
- ✅ Avoid wheels with offset below 18mm or above 38mm to prevent brake caliper or suspension contact.
- ✅ If using aftermarket wheels, confirm hub bore is at least 116.7mm and use hub-centric rings; never rely on lug nuts for centering.
