What is the OEM tire size for a 2001 Chevy silverado?

The OEM tire size for a 2001 Chevy Silverado varies depending on the trim level, cab style (regular, extended, crew), and whether it's a 2WD or 4WD model. There's no single answer.

To find the correct size, you should:

* Check the sticker on the driver's side doorjamb: This sticker lists the recommended tire size and inflation pressure. This is the most reliable source.

* Look at the sidewall of your existing tires (if you still have the originals): The size is printed directly on the tire sidewall.

* Consult your owner's manual: The owner's manual should specify the OEM tire sizes for your specific Silverado configuration.

Without knowing the specific configuration of your 2001 Silverado, I cannot provide the correct tire size.
