The better traction manages to ease the driving pressure off the tire during the drive. The result is a slower tread wear rate. This, along with the asymmetric tread design's prevention of irregular wear, lengthens the tire's tread life and usability. The improved traction and the lowered tire weight manage to decrease the rolling resistance as well. The rolling resistance is the pressure that determines how much energy the vehicle needs to maintain the tire's motion, and the lower it is the less fuel the vehicle consumes. The reduced fuel consumption decreases the vehicle's CO2 emissions as well, offering an environmentally friendly tire.
