General Motors is partnering with researchers at the new National Tire Research Center in Virginia to improve fuel economy through the development of new tire technology, according to autoblog.com and Automotive News.
Variations in tread pattern, construction and material quality are just a few factors that determine the rolling resistance of a tire. Vehicles with lower rolling resistance require less fuel to move the vehicle forward, and can help increase fuel efficiency by as much as 7 percent.
