Simply put, Mr. Tuffy (or Earthguard Equivalent) prevents puncture flats. When placed between tire and tube, it provides a protective layer between road hazards and the inner tube. Thorns or glass that may penetrate the tire are blocked from the inner tube.
- Proven Tough - For over three decades Mr. Tuffy has been the world's leading flat-tire preventive with Millions upon Millions of satisfied cyclists.
- Lightweight - Weighs less than liquid fills and thorn-resistant tubes. New Ultra Lite weighs even less.
- Easy Installation - No gooey mess.
Main Line of Defense - The leading flat prevention product is Tire Liners - and the most popular brand of tire liner is "Mr. Tuffy Tire Liners."
Tire Liners (aka Tube Protectors) shield against punctures from thorns, glass, and road debris - the nemesis of every bicyclist.
Strong Stuff! - Made of durable, lightweight urethane, Mr. Tuffy provides a protective layer between the outer tire and inner tube. Urethane has a property which makes it very elastic. When a thorn or piece of glass attempts to penetrate the Mr. Tuffy liner it comes up against a surface that is both hard and elastic. The object pushes against the surface which gives way while resisting initial penetration.
2 Layers Tuff - With the introduction of the dual layer Mr. Tuffy over 10 years ago, we made our liners even more impenetrable by fusing a hardened strip to the original pliant, lightweight urethane strip. This Micro-Shell layer provides an even better shield against punctures.
Absolutely, Positively - Will not cause tire or tube damage-or loosen spokes
PACKAGE CONTAINS TWO 29 X 1.5 - 2.0 PROTECTIVE STRIPS: These will need to be cut and fitted to size since 16 and 12.5 inch stroller tires are smaller. Simply cut to desired length with some overlap. Place tire liner between the tire and inner tube with the overlap opposite the valve stem to help balance the wheel.
You may receive the bulk version of Mr Tuffy (Earthguards) which eliminates the packaging.
All Earthguard Tire Liners are now made with a new additive that causes them to biodegrade once disposed of in a landfill or composting facility after a long and useful life. Within 1-5 years of disposal, our tire liners will totally degrade into what is called biomass (a fertilizer) and a biogas that can be converted into energy.
