Last year, leading tire manufacturer Goodyear received a $1.5 million grant, according to AutoBlog, to develop self-inflating tires from the Department of Energy’s Vehicle Technology. The potential benefits are self-explanatory; fewer flat tires and under-inflated tires diminish fuel economy.
They would be great for anyone but, Goodyear is more concerned with semi-truck drivers. The tires, fitted with Goodyear’s proprietary “Air Maintenance Technology,” could be a serious boon to the trucking industry. They work by an internal regulator and pump. When the tire senses under-inflation, the regulator opens, pumping air in until the tire reaches the correct pressure.
