Frequently Asked Questions
- What size tires does a Pontiac Grand Prix use?
- The Pontiac Grand Prix tire size varies by trim level and model year. Base trims typically use smaller wheels (16") while higher trims use 17" or 18" wheels. Check the breakdown below for your specific year and trim.
- What is the correct tire pressure for a Pontiac Grand Prix?
- Recommended tire pressure for the Pontiac Grand Prix is typically 32-36 PSI. The exact specification is on the sticker inside the driver's door jamb. Do NOT use the "max pressure" number on the tire sidewall.
- Can I put bigger tires on my Pontiac Grand Prix?
- You can typically go one size up in width (e.g., 215 to 225) without issues. Going up in diameter (e.g., 16" to 17") requires matching wheels and may affect speedometer accuracy. Extreme upsizing can cause rubbing and void warranty.
