Once deep external cuts, chunking and edge cut have occurred, the danger of water and mud penetrating the rubber track is greatly increased. Moisture attacks the embedded steel cord. Depending on the severity of the damage and working conditions, the tensile strength of rusted steel cords weakens and can lead to breakage.
Thanks to Bridgestone's world leading tire technology, our engineers have developed an advanced Anti-Rust Steel cord which minimizes deterioration caused by rust.
Even when moisture/mud penetrates from external cuts, steel cord tensile strength is maintained for longer.
Salt bath testing carried out over 7 days has proved over 41% improvement in performance compared with standard steel cord.
