When should you carry Park Tool Emergency Tire Boots?

Park Tool Emergency Tire Boots are a trail-side and roadside lifesaver for riders who find themselves with a sidewall cut or gash that a tube alone can't hold. Constructed from a durable, flexible material, they install inside the tire casing to bridge the damaged section and create a stable backing that lets a fresh tube hold pressure long enough to finish the ride or get home safely.

Compact and lightweight, these tire boots take up almost no space in a jersey pocket, saddle bag, or pack, making them one of the highest-value items in any repair kit. No tools required: peel, stick, and ride. Keep a few on hand because sidewall damage has a way of showing up at the worst possible time.
