Will a Pontiac rim fit Chevrolet?

Maybe. It depends on the specific year, make, and model of both the Pontiac and the Chevrolet, as well as the size and bolt pattern of the rims. While both brands are (or were) under General Motors, there's no guarantee of interchangeability.

To know for sure, you need to:

* Find the bolt pattern: This is the number of lug nuts and the diameter of the circle they form. It's usually written as something like "5x114.3" (five lug nuts, 114.3mm diameter).

* Check the wheel diameter and width: The diameter is the overall size of the rim (e.g., 17 inches), and the width is how wide the rim is (e.g., 7 inches).

* Compare the offset: This is the distance between the mounting surface of the wheel and the centerline of the wheel. A significantly different offset can cause problems.

* Check for hub bore: This is the diameter of the center hole in the rim. It needs to fit over the hub of the Chevrolet.

* Consider backspacing: This measures the distance from the mounting surface of the wheel to the inside edge of the wheel.

If all these specifications match, then the Pontiac rim *might* fit the Chevrolet. However, even with matching specifications, there's always a slight chance of interference with brakes or suspension components. It's best to double-check compatibility before purchasing or installing.
