What should be done if a tire is found to be significantly larger requiring suspension modification?

When a tire is found to be significantly larger and requires suspension modification, rejecting the tires is the appropriate action. This is because larger tires can alter the vehicle's handling characteristics, potentially affecting safety and performance. They may exceed the manufacturer's specifications, which can lead to excessive wear on suspension components or unanticipated handling issues.

Rejecting the tires ensures that the vehicle remains within safe operational limits as prescribed by the manufacturer. It preserves the integrity of the vehicle's design and engineering, which is critical for both safety and compliance with inspection standards. Accepting larger tires without appropriate modifications would violate regulations aimed at maintaining vehicle performance standards.
