How is a flat tire repaired?

AS WITH ANY AUTOMOTIVE REPAIR, A TIRE REPAIR REQUIRES PRECISION AND ACCURACY TO ATTAIN MAXIMUM SAFETY AND EFFECTIVENESS. PUNCTURES IN THE TREAD OF A TIRE CAN BE REPAIRED WITH A PLUG-PATCH PROCESS. THIS IS ACHIEVED BY INSPECTING THE TIRE TO IDENTIFY THE LEAK. DISMOUNTING THE TIRE TO CHECK IT FOR FURTHER DAMAGE. IF PRESENT, REMOVING ANY EMBEDDED OR PENETRATING OBJECTS FROM THE TIRE AND CHECKING THE TIRE TO DETERMINE IF ANY SEPARATION IS PRESENT. WHEN IT IS DETERMINED THAT THE REPAIR IS APPROPRIATE , THEN THE SURFACE IS PREPARED, AND IN MOST CASES A PLUG-PATCH ASSEMBLY IS USED TO REPAIR THE TIRE, THERE ARE CIRCUMSTANCES WHEN A PLUG IS INSERTED IN THE PUNCTURE AND THEN A PATCH IS FITTED OVER THE PLUG TO ACHIEVE A PERMANENT REPAIR. THE TIRE IS RE-INSTALLED ON THE RIM AND THEN THE VEHICLE.
