The Tru-Align mounting system is an OPTIONAL service that allows for mounting a special adapter plate with special mounting studs that only touch YOUR EXPENSIVE WHEELS at the lug holes.  This keeps all metal away from the finish of your wheels.  This service may also be required for tires with rim-guards.
