Why is it important to clean the inside of a wheel?

Cleaning the inside of a wheel is crucial to ensure proper adhesion of wheel weights. When wheel weights are attached to the wheel, they must have a clean surface to bond effectively, allowing them to remain in place while the vehicle is in motion. Any dirt, grime, or oxidation present on the wheel’s surface can prevent the weights from adhering properly, leading to imbalances that can cause vibrations and uneven tire wear. This is particularly important in maintaining the safety and performance of the vehicle, as an unbalanced wheel can affect handling and stability.

While other factors like aesthetics, rust prevention, and road noise have their importance, the pressing need for wheel weights to adhere securely makes the cleanliness of the wheel's interior essential for optimal tire service and safety.
