Coda develops its self-inflating tire technology

Coda Development has undertaken testing of its self-inflating tire (SIT) technology and has developed a retrofit and a retread SIT

by Rachel Evans

 

In 2009, Coda Development's self-inflating tire (SIT) technology received Tire Technology of the Year in the Tire Technology Expo Awards. Further to its recent R&D, the company is now seeking partners to implement the technology on a wider scale.

Maros Topoli, marketing director and partner at Coda Development, says "We believe the SIT is a high added value and low cost innovation with potential to influence the whole tire industry. We also believe that adoption of SIT by major tire manufacturers would bring significant improvements to road safety and economy. On a large scale, it could bring serious reduction of CO₂ emissions globally."

Coda has since successfully tested the key components of SIT – the peristaltic tube chamber and automatic pressure regulator. "We have conducted high speed regulator tests with an independent testing company as well as the Czech Technical University in Prague. Furthermore, we have developed additional embodiments of SIT such as retrofit and retread SIT."

Significant efforts have also been put into expansion and strengthening of its patent portfolio, which currently consists of 13 granted patents and 36 pending application covering 80% of the global tire market including USA, Europe, Japan, India and China.

In order to boost prototyping efforts Coda has increased additional funding and is now looking for an industry partner to jointly implement SIT technology. "The technology in its design is very simple consisting of only two new tire components – a tire contained peristaltic pump chamber and a regulator that is not much more complicated than a regular valve. Therefore, once R&D is completed, implementation on wider scale would be fully viable," notes Topoli.
