Penetrant Inspection → Overhaul

Per CMM: Per CMM, any wheel requiring penetrant inspection is processed as an overhaul. Owners may elect overhaul at any tire change to extend service life.

Standard Tire Change Scope

Every tire change replaces the tire, the main wheel-half preformed packing (O-ring), the valve cap, and the valve core. Specific part numbers and dash sizes vary by wheel and are pulled from the CMM at the time of service.
