What Makes Mr Tuffy Tire Liners Your Best Flat Defense?

Mr Tuffy Tire Liners are the original puncture protection solution trusted by cyclists for decades. Installing between the tire and tube, they create a passive physical barrier that blocks thorns, glass, staples, and road debris before they can reach your tube. Made from polyurethane, the Ultra Lite construction delivers meaningful flat protection while keeping the weight penalty to a minimum. This pair fits 27 x 1-1/8 to 1-1/4" tires as well as 700 x 28-32mm road and commuter tires.

Unlike liquid sealants that can dry out or clog valve stems, these liners are a set-it-and-forget-it solution with zero ongoing maintenance. Installation takes minutes without any special tools: seat the liner between the tire casing and tube before inflating. The polyurethane construction resists breakdown from road grime, UV exposure, and temperature swings, making them a long-term investment in flat-free riding. A practical choice for commuters, recreational riders, and everyday cyclists who are tired of roadside puncture stops.
