Does 1999 Chevy z71 wheels interchange with 2007?

While both are Chevy Z71s, the wheel bolt patterns and possibly the wheel size (diameter and width) may differ between a 1999 and a 2007 model. Therefore, they are not guaranteed to interchange.

You need to check the following for both the 1999 and 2007 Z71:

* Bolt Pattern: This refers to the number of lug nuts and the diameter of the circle they form. (e.g., 6x139.7mm) This is the most crucial factor. If they don't match, the wheels won't fit.

* Wheel Diameter: (e.g., 15", 16", 17", etc.) The diameter must be compatible with your tire size and suspension.

* Wheel Width: (e.g., 7", 8", etc.) The width should be appropriate for the tire.

* Backspacing: This is the distance between the mounting surface of the wheel and the innermost part of the wheel. Incorrect backspacing can cause clearance issues with the brakes, suspension, or body.

* Center Bore: The size of the hole in the center of the wheel that fits over the hub.

Unless you're absolutely certain the specifications are identical, it's best to verify the wheel specifications on the wheels themselves (usually stamped on the back) or use a wheel fitment guide with the year, make, and model of both vehicles. A tire shop can also help you verify compatibility.
