Inspection and Verification (Start Testing Here)
Visually examine front and rear tires and wheel assemblies for damage such as uneven wear, tread washouts, or sidewall damage. Make sure the tires are of the same size, type and, where possible, same manufacturer. Any tire or wheel that is damaged should be replaced.
Wheels and tires must be cleared of any foreign matter, and tire pressures adjusted to the correct specification.
If tires exhibit uneven wear or feathering, the cause must be corrected. Check steering and suspension components for damage/wear and, if necessary, check and adjust steering alignment.
For a more involved testing procedure refer to Brake Systems (The Basics).
