The story

Dayco was founded in 1905 as Dayton Rubber Manufacturing Co. by Col. J. C. Hooven in Ohio. The company initially made products such as garden hoses out of natural rubber. In 1908, the company hired John A. MacMillan, and began creating his product, the airless tire. The company also produced the first whitewall tires in 1913. Beginning in the early 1920s, the company entered a diversification period when it radically increased the variety of its products. Dayco would eventually make many different rubber parts, as well as some textiles. It also pioneered some synthetic rubber products, including developing the first synthetic rubber tire. The company would be a valuable supplier of military products during World War II. The company officially changed its name to the DAYCO Corporation in 1960.
