What is Flat-Proofing TyrLyner®?

TyrLyner® is a permanent, self-healing polyurethane rubber that is securely adhered to the inside of the tire casing. TyrLyner® heals over cuts, punctures and penetrating objects, and will prevent tires from going flat if punctured or cut by objects up to 3/8-inch in diameter. TyrLyner® offers sidewall protection as well as protection for the tread face area of the tire. The patented process allows the liner to immediately close over the zone of penetration and completely fuse, thus preventing loss of air pressure.

Tireliner Example

Example of Tireliner

Tire balance and structural integrity are not affected by the addition of the liner material. TyrLyner® is excellent for applications where added weight may be undesirable or will create a problem. Tires with TyrLyner® are recappable, repairable, and unaffected by temperature extremes or tire air pressure.

Unlike any other product on the market, TyrLyner® is a puncture-sealing system that offers true sidewall protection, as well as protection for tread areas. It provides a balanced, uniform thickness of self-healing rubber, and it’s the only available system that conforms to any size tire.

How Does It Work?

When a puncture occurs, the centrifugal force of the rotating tire and internal pressure forces the TyrLyner® into the puncture zone, causing a permanent seal.
