Most punctures, nail holes or cuts up to ¼" confined to the tread may be satisfactorily repaired by trained personnel using industry-approved procedures.
Change your flat tire out with your spare tire. Then visit an authorized BFGoodrich Tire dealer for an inspection as soon as possible. (You can find a dealer near you by using the Dealer Locator to the right.) They can then determine what damage your tire has, and whether to repair or replace your tire.
