The Park Tool TB-2 Emergency Tire Boot is a rugged, compact patch designed to help you quickly reinforce a tire sidewall or puncture-prone area when you’re far from home, on the trail, or mid-ride. Tire damage like cuts, large punctures, or significant sidewall tears can leave you stranded if you don’t have a reliable way to shore up the casing. The TB-2 steps in to provide a strong, flexible patch that supports the compromised area so you can finish your ride safely and get to a proper repair location.

Constructed from reinforced material, this tire boot resists abrasion and flex while bearing the forces of tire rotation and inflation. Its size is generous enough to cover most common tire damage zones yet compact enough to fit easily in a saddlebag, pack, or jersey pocket. Using it is simple: just place the boot on the inside of the tire over the damaged section, mount the tube or insert, and inflate. The boot helps spread the load and keep the tube from bulging through the cut, allowing you to ride to safety without making a permanent repair on the roadside.

Whether you’re tackling rugged mountain terrain, rough gravel roads, or everyday commuting potholes, carrying an emergency tire boot like the Park Tool TB-2 adds peace of mind and practicality to your toolkit. It’s a small, inexpensive insurance policy that helps turn potential ride-ending flats into manageable situations.
