The Park Tool TB-2 Tire Boot Kit is a compact emergency repair solution for punctured bicycle tires. Each kit contains three strong, self-adhesive synthetic patches designed to temporarily reinforce a tire's sidewall or tread from the inside, preventing the inner tube from blowing through until a permanent repair or tire replacement can be made.

• Set of 3 emergency tire patches for cut on damaged tires
• Made of a thin, extra tough film developped by 3M (maintains patch in place upon reinstallation)
