Can a punctured or flat tire be repaired safely?
If a tire loses most of its air pressure, it must be removed from the wheel for a complete internal inspection to be sure it’s not damaged. Tires that are run even short distances while flat are often damaged beyond repair. Most punctures, nail holes or cuts up to 1/4 inch–confined to the tread–may be satisfactorily repaired by trained personnel using industry-approved methods. Don’t repair tires with tread punctures larger than 1/4 inch, or any sidewall puncture. Also, never repair tires which are worn below 1/16 inch tread depth.
