Pinewood Derby Wheel
Go/No-go Gauge

Speed up your race inspection and make it consistent!

Our Wheel Go/No-go gauge will help you improve your race by providing a consistent and quick way to inspect pinewood derby wheels while the wheels are mounted on the car.


The Wheel Go/No-go gauge allows you to easily measure the following criteria:

Wheel Passes the 1.170 OD Check

Wheel Fails the 1.170 OD Check

Wheel Passes a .360 Width Check

Wheel Fails the .360 Width Check

  1. Do not force the gauge over a wheel. The gauges are sized one-thousandth of an inch smaller than the printed measurement. So if, for example, a wheel measures exactly 1.170, it will not fit into the 1.170 OD gauge (because it complies with the 1.170 minimum OD specification).

  2. The gauge measures the overall width of the wheel including the sidewall. The tread patch is not measured by itself, as it is not easily measured on most wheels. When measuring the wheel width, measure at a point on the wheel where there is no raised lettering.

  3. If your organization uses a slightly different specification for diameter or width, consider changing the specification to those supported by the tool.

  4. Tip: To make sure the correct gauge is used, tape over the gauges that are not to be used.

  5. If a car is built with wheel wells, the OD gauges cannot be used (of course a digital caliper cannot be used in this situation either).
