These tire boots from Park Tool are designed to provide a temporary fix for larger cuts or slices in a tire casing that would otherwise allow an inner tube to bulge through. Their reinforced adhesive backing helps them stay in place inside the tire, creating a stable surface so you can install a tube and continue riding. Sized for quick use on the trail or road, they offer a reliable solution for getting home when a tire is too damaged for sealant or a standard patch to handle.
