What size tires does a Infiniti M45 use?

The Infiniti M45 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 Infiniti M45?

Recommended tire pressure for the Infiniti M45 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 Infiniti M45?

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.

How often should I rotate Infiniti M45 tires?

Rotate your Infiniti M45 tires every 5,000-7,500 miles for even wear. Front-wheel drive vehicles wear front tires faster, so regular rotation is especially important.
