What size tires are on 2001 Chevy Impala?

The tire size on a 2001 Chevy Impala depends on the trim level and options chosen when the car was new. There wasn't a single standard size. To know for sure, you need to:

* Check the sticker on the driver's side doorjamb: This sticker will list the recommended tire size and inflation pressure for your specific vehicle.

* Check the sidewall of your existing tires: The size is printed directly on the sidewall of each tire. It will be a series of numbers and letters (e.g., P215/65R15).

Without access to your car's information, I can't tell you the exact tire size.
