What is the factory wheel size on a 2000 Chevrolet Z71?

The factory wheel size on a 2000 Chevrolet Silverado Z71 (it's a Silverado, not just a Z71 trim level) varied slightly depending on options. You'll find either 16-inch or 17-inch wheels as factory options. To know for sure what size *your* specific truck came with, you need to check:

* The sticker on the driver's side doorjamb: This will list the tire size. The wheel size can be inferred from the tire size.

* The wheels themselves: The size is usually cast into the wheel.

Don't rely solely on general information; always check your vehicle's documentation or the wheels themselves for definitive information.
