The lowered tire compound and better road contact decrease the rolling resistance, which is the force that determines how much energy the vehicle needs to maintain the tire's motion. The reduced rolling resistance decreases the vehicle's fuel consumption and CO2 emissions, making the model environmentally friendly. This also slows the tread wear rate down. It, along with the prevention of irregular tread wear by the computer optimized tread design, extends the tread life and the tire's usability by promoting a slower even tread wear.
