Expert Buying Guide for 1992 Chevrolet Sportvan G20
For your 1992 Chevrolet Sportvan G20, the critical fitment specs are a 5x127 bolt pattern, 78.3mm center bore, and 0-15mm offset. The 78.3mm bore is hub-centric; aftermarket wheels with a larger bore require hub-centric rings to prevent vibration and ensure load is on the hub, not the lug nuts. Offset within 0-15mm maintains proper scrub radius and clearance. Use only 1/2-20 lug nuts with the correct seat (cone or ball) matching your wheels; mismatched seats can cause loosening. Always torque to manufacturer specs and re-torque after 50 miles.
