Self-inflating tyres

Never pump up your tyres again with the help of these amazing new tyres.

Imagine never having to pump up your rubber again! That’s the idea of the new Self Inflating Tyre (SIT).It uses the principle of an in-built ‘peristaltic pump’, which is basically a thin tubing of rubber that uses the rolling effect of the wheel to constantly top up the pressure. The system also includes a special valve that ensures the tyre is not over-inflated. Czech-based Coda Development is behind the technology, which is designed to prevent people running on underinflated tyres. Doing so reduces grip and increases fuel consumption, plus the chances of a dangerous blow out. And while auto-inflating tyres already exist for commercial vehicles, they use more complicated and pricier air compressor and pump systems, which limits their applications.Source
