Frequently Asked Questions
- What size tires does a Cadillac CT6 use?
- The Cadillac CT6 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 Cadillac CT6?
- Recommended tire pressure for the Cadillac CT6 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 Cadillac CT6?
- 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.
