Expert Buying Guide for 1998 Chevrolet 3500 Crew Cab
For your 1998 Chevrolet 3500 Crew Cab, the 8x165.1 bolt pattern is shared with 1992–2000 models. The 116.7mm center bore is critical: aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive; stock is around 20mm. Sticking close to this range maintains proper suspension geometry and tire clearance. Safety warning: use only 14x1.5 lug nuts with the correct seat (cone or ball seat) to match your wheels. Mismatched seats can cause loosening or wheel damage. Always verify lug nut type before installation.
