B.F. Goodrich Co. announces development of tubeless tire - May 11, 1947 - HISTORY.com

On this day in 1947, the B.F. Goodrich Company of Akron, Ohio, announces it has developed a tubeless tire, a technological innovation that would make automobiles safer and more efficient.

The culmination of more than three years of engineering, Goodrich’s tubeless tire effectively eliminated the inner tube, trapping the pressurized air within the tire walls themselves. By reinforcing those walls, the company claimed, they were able to combine the puncture-sealing features of inner tubes with an improved ease of riding, high resistance to bruising and superior retention of air pressure. While Goodrich awaited approval from the U.S. Patent Office, the tubeless tires underwent high-speed road testing, were put in service on a fleet of taxis and were used by Ohio state police cars and a number of privately owned passenger cars.
