What is tyre sealant, also called tyre slime?
Tyre sealant or tyre slime is a viscous green or coloured liquid that is injected into your tyre to prevent flats or seal ones that have occurred.
Tube sealant is a liquid latex that can be pumped into the inner tube using the same valve that inflates the tyre. As the wheel turns, the fluid circulates the inside of the tube.
When a hole occurs, the fluid spills into it and soon dries, filling the hole and plugging the leak. It acts in the same way as blood clots to avoid bleeding in a wound. Both penetration and pinch punctures are covered by the sealant.
Punctures that are 2.5cm or smaller can be sealed with tyre sealant. Glass and staples, for example, are much smaller than most surface debris. The smaller the puncture, the better the chances of it sealing properly and easily. However, punctures or tyre failures that cause a blowout cannot be prevented or repaired with tyre sealant. Blowouts are usually caused by major tyre or inner tube failure, pinch flats, overvaluation, or extremely large punctures.
We like tyre sealant because it is cheap and applying it to your tyres is a breeze.
