It prevents heat build-up during the drive, which eases the pressure off the tire. The rolling resistance is the pressure affecting the model which determines how much energy the vehicle needs to keep the tire in motion. The lower rolling resistance, in turn, decreases the vehicle's fuel consumption and CO2 emissions and slows the tread wear rate down. In other words, it makes the model more fuel efficient and environmentally friendly, while lengthening the tread life and the tire's usability.
