Initial Inspection and Diagnostic Overview

NOTE: Prior to performing any diagnosis, make sure the brake system warning indicator is functional.

Visually examine front and rear tires and wheel assemblies for damage such as uneven wear patterns, tread worn out 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 or excessively worn should be replaced.

Wheels and tires must be cleared of any foreign matter, and tire pressure adjusted to the correct specification.

If tires exhibit uneven wear or feathering, the cause must be corrected. Check steering and suspension components for damage or wear and, if necessary, check and adjust front alignment.
