Bridgestone shows future technology
Having introduced an entire new line of truck tires last year, Bridgestone Firestone North American Tire is going back to basics, developing new designs for core tire components. At a technology preview during its annual dealer meeting, the company displayed new approaches to casing design and materials intended to increase both durability and resistance to irregular wear. It also offered a look at a variety of tire pressure monitoring systems that could be used to meet any future federal moves to require such remote monitoring.
A new belt package on display uses less material than current tire casing designs, yet provides a stiffer platform for the tread. The lighter, stiffer package could have a positive impact on both original tread life and casing durability, according to Guy Walenga, engineering manager-NA Commercial Products.
Company engineers are also looking at a new approach to tire bead design that will provide a stronger bead, more resistance to bead damage, and result in greater durability over the entire life of a casing.
The third core technology unveiled was a new inner liner made with a higher level of clay in its chemical composition. Called SuperSealant, it will cut moisture migration through the casing by 50%, Walenga said, not only reducing tire air loss but also protecting the casing elements from breakdown due to moisture exposure.
