Bridgestone Bandag Tire Solutions’ Bridgestone-brand Greatec R125 wide-base trailer radial, designed for low rolling resistance and increased payload, is approved for use on U.S. Environmental Protection Agency SmartWay-certified equipment and is suited for fleets running California Air Resources Board-compliant vehicles. Greatec R125 uses several irregular-wear-fighting proprietary technologies to facilitate long, even tread life, including Bridgestone’s Equalizer Rib and Defense Groove designs that promote uniform rib wear for longer mileage.
Stress-relief sipes help absorb rib stresses for even wear, while tough sidewall protector ribs on both sides help fight curbing damage to protect the casing; should the protector rib on one side wear away, the tire can be flipped over for continued protection. The Greatec R125 uses casing-saving stone rejector platforms in each tread groove to help prevent trapped stones from pushing deeper into the tread grooves and piercing the belt layer, damaging the belts and exposing them to rust.
The R125 benefits from Bridgestone’s proprietary Waved Belt design that helps balance stiffness and resiliency to facilitate a strong, stable casing that, in turn, produces a stable footprint shape throughout the life of the tire. The T.I.P. (Turn-In Ply) design helps increase bead durability by removing the ply end from harm’s way and wrapping it around the bead bundle to promote a stronger, more resilient bead.
