Expert Buying Guide for 1998 Chevrolet Express 2500 Passenger
For your 1998 Chevrolet Express 2500 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 (e.g., 125mm), requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the studs. The factory offset is 28mm; deviations affect scrub radius and steering feel. Use only 14x1.5 lug nuts with the correct seat type (cone or ball) to avoid loosening. Always torque to spec (140 ft-lbs) and re-torque after 50 miles.
