Run-flat tires usually can not be fixed. The tires are usually $100 more than because they contain more rubber on the sidewalls & surface so they can run flat, therefore it they usually can not be repaired or plugged for safety reasons. For more information, call your local tire center. (Note: do not mix run-flats with non-run flat tires.)

That cannot be done. If broken, the tire is useless.
