It's probably not possible to protect yourself from ever getting a puncture again, but puncture protection inserts in tyres have proven to offer very effective protection against broken glass and similar threats - especially in everyday life. In addition to tyres with already integrated puncture protection inserts, there are also puncture protection inserts that can be retrofitted in existing tyres. Here, a puncture-proof liner is placed under the tread between tyre and inner tube. If you get a puncture, the puncture sprays and sealing milk liquids offered here offer a good and quick alternative to conventional repair kits. The fluid is filled in via the valve (without removing the tyre) and seals minor defects from the inside with the support of the air pressure.
