Expert Buying Guide for 1998 Chevrolet Express 1500 Passenger
For your 1998 Chevrolet Express 1500 Passenger, the 6x139.7 bolt pattern is shared across 1996–2014 models, but the 78.1mm center bore is critical. Aftermarket wheels often have a larger bore; use hub-centric rings to prevent vibration and ensure proper load transfer. Offset must stay within 24–28mm; deviations risk rubbing or poor handling. Always verify lug nut thread pitch (14x1.5) and seat type—factory uses cone seat. Never mix seat types; use correct lug nuts to avoid wheel loss. Re-torque after 50–100 miles.
