Revive worn knobby tires with the lightweight Hardline Knobby Cutting Tool. The Tread Doctor uses a heated carbide blade to trim and reshape dull knobs, restoring grip and extending tire life so you get “like-new” traction without replacing the tire.
Get more traction for every ride. The Hardline Tread Doctor pays for itself by improving performance and prolonging tire life — an essential tool for riders who demand peak grip and value.
