The optimal casing design and shape enhances the tire's road contact and traction, which lowers its rolling resistance. The rolling resistance is the external driving pressure affecting the tire, which determines how much energy the vehicle needs to keep it in motion. The reduced rolling resistance significantly lessens the vehicle's fuel consumption and CO2 emissions, while it also slows the tread wear rate down. In this manner, the tire promotes a longer lasting tread life and a fuel efficient and environmentally friendly performance.
