This allows the tire to decrease its rolling resistance by easing the driving pressure off the tire. The reduced rolling resistance lessens the vehicle's fuel consumption and CO2 emissions, offering an environmentally friendly and fuel efficient driving experience. The lower rolling resistance also manages to extend the tread life. It slows the tread wear rate down, which, along with the even tread wear provided by the optimized siping design of the tread, extend the tire's usability as well.
