The silica tire compound succeeds in lowering the fuel consumption and the CO2 emissions of the vehicle. This is achieved as the silica compound and the lightweight tire construction decrease the tire's rolling resistance, which is a pressure affecting the tire that determines how much energy the vehicle needs to maintain the tire's motion. The reduced rolling resistance also extends the tire life as it eases the driving pressure off the tire. It slows the tread wear rate down significantly, increasing the tread life and the tire's usability. The fuel efficient drive and the longer lasting tread life make the tire environmentally friendly and budget conscious.
