It increases the road gripping ability and takes the pressure off the tire. In this manner, it manages to lower the rolling resistance. The rolling resistance is the pressure affecting the tire that determines how much energy the vehicle needs to maintain the tire's motion. The decreased rolling resistance reduces the fuel consumption and CO2 emissions of the vehicle. It also slows down the tread wear rate, allowing the tire to be used for a longer period of time. The tread pattern manages to evenly distribute the driving pressure along the tread area, preventing irregular wear. The combination of these aspects ensures a fuel efficient and long lasting tire model.
