Expert Buying Guide for 2002 Pontiac Grand Prix
For your 2002 Pontiac Grand Prix, the critical fitment specs are bolt pattern 5x115, center bore 70.3mm, offset 52mm, and lug nut size M12x1.5. The 70.3mm center bore is hub-centric; aftermarket wheels with larger bores require hub-centric rings to prevent vibration and ensure proper load transfer. Offset is sensitive: staying within ±5mm of 52mm is recommended to avoid rubbing or clearance issues. Always use the correct lug nuts: M12x1.5 thread pitch with a conical (60-degree) or ball seat matching the wheel. Improper lug nuts can cause wheel loosening or damage. Re-torque after 50-100 miles.
