The Washington Multi-piece Rim Matching Chart is a tool used to accurately identify and match a variety of wheel and rim types. It is based on the Washington Car Wheel Identification System, which is a system used to identify and classify different wheel and rim sizes. The chart is composed of several sheets of paper that are overlaid one on top of the other. Each sheet contains a different set of measurements for each wheel or rim type. The measurements are listed in millimeters and can be used to identify the appropriate wheel or rim type for a particular vehicle. There are several types of Washington Multi-piece Rim Matching Chart, such as the Standard Chart, the Euro Chart, and the Off-Road Chart. The Standard Chart is the most commonly used, as it is designed to work with the majority of vehicles. The Euro Chart is designed for European vehicles, while the Off-Road Chart is used for vehicles that are used off-road.
