TOKYO (Sept. 7, 2012)—Bridgestone Corp. has developed a truck and bus tire manufacturing technology that incorporates elements of retreading that it claims will reduce resource consumption and improve fuel efficiency.
Called Trisaver—for the three types of savings it enables: costs, resources and CO2 emissions — the technology seeks to improve the performance of the tire by optimizing each component's production throughout the process.
Bridgestone did not quantify the savings it expects to gain through the new process but did say it expects to achieve reduced rolling resistance and to increase the number of times a tire can be retreaded.
Bridgestone referenced its 2007 acquisition of retreading systems developer and supplier Bandag Inc. and said development of the technology focused on the basic difference in the retread manufacturing process versus that for new tires.
This led Bridgestone to claim that it discovered that the “overall performance of the tire can be improved by manufacturing the casing and tread through a process that is optimal for each component.”
Bridgestone did not say where it is implementing the new technology or how soon it might be implemented on a commercial scale. It did say it is conducting road trials and analyzing product marketability.
Bridgestone said this development ties into its long-term environmental goals of using 100-percent sustainable materials and contributing to reaching the globally agreed target for reducing greenhouse gas emissions of at least 50 percent by 2050.
