Bridgestone launches Trisaver retread technology

ERJ staff report (LMH)

Tokyo - Bridgestone Corp. says it has developed a new truck and bus tyre manufacturing technology that will result in both significant resource conservation and enhanced fuel efficiency. The new technology is called Trisaver, a reference to the three types of savings it enables: savings of costs, resources and CO2 emissions.

Since acquiring Bandag Inc. in 2007, Bridgestone has been in development of a global solutions business using retread tyres and Bandag's retread technology. While new tyres are manufactured by vulcanising all the materials at once, retread tyre manufacturing bonds together a separate and previously vulcanised casing and the tread.

Focusing on this basic difference in manufacturing methods, Bridgestone has discovered that overall performance of the tyre can be improved by manufacturing the casing and tread through a process that is optimal for each component.

Bridgestone claims its new technology greatly reduces rolling resistance compared to conventional tyres, and at the same time enhances durability, thereby potentially increasing the number of times the tyre can be retreaded.

It also said that Trisaver offers value through cost savings, since greater durability means the tyre can be retreaded more times, and improved fuel efficiency through lower rolling resistance. At the same time, the technology benefits the environment by using resources more effectively and reducing CO2 emissions.

With plans to market this new technology in the near future, Bridgestone is in the process of conducting road trials and analyzing product marketability.
