Bridgestone Bandag Tire Solutions has introduced a new wide base semi-trailer radial engineered for low rolling resistance and increased payload.
The Greatec R125 is approved for use on Environmental Protection Agency (EPA) SmartWay-certified vehicles and is compliant with fleets running under California Air Resources Board (CARB) standards.
According to brand manager Chris Hoffman, the new release “is an excellent choice for fleets who prefer to use wide base single trailer tires to increase revenue-producing payload. Its design also promotes superior rolling resistance, making it an excellent choice for those participating in the SmartWay transportation partnership.”
The CARB-compliance aspect is especially important, he notes. “Starting this year, all 2011 model-year trailers must use low rolling resistance tires certified by SmartWay in order to run in California,” says Hoffman. “Within three years, that rule applies to all trailers 53 feet and longer.”
Equalizer Rib and Defense Groove elements on the R125 promote uniform rib wear for longer mileage as stress-relief sipes absorb rib stresses for even wear.
Sidewall protector ribs on both sides fight curbing damage to protect the casing, he says. “Should the protector rib on one side wear away, the tire can be flipped over for continued protection.”
It uses casing-saving stone rejector platforms in each tread groove to help prevent trapped stones from pushing in deeper and piercing the belt layer, damaging the belts and exposing them to rust.
A Waved Belt design balances stiffness and resiliency to provide a strong, stable casing that, in turn, produces a stable footprint shape throughout the life of the tire, according to Hoffman. “The TIP (Turn-In Ply) design increases bead durability by removing the ply end from harm’s way, wrapping it around the bead bundle – an innovation that promotes a stronger, more resilient bead.”
