Continental AG, commonly known as Continental, is a German multinational automotive parts manufacturing company specializing in brake systems, interior electronics, automotive safety, powertrain and chassis components, tachographs, tires and other parts for the automotive and transportation industries. Continental is based in Hanover, Lower Saxony, Germany. Continental is the world's fourth-largest tire manufacturer.
Continental was founded in 1871 as a rubber manufacturer, Continental-Caoutchouc und Gutta-Percha Compagnie. In 1898, Continental started development and production of the vehicle tires with plain tread, which was the major success of the brand. In 1904, Continental became the first company in the world to manufacture grooved vehicle tires.
The grooves are also called The Tread Pattern.
• They are usually provided to increase the tractive force.
• The grooves are designed to allow water to be expelled from beneath the tire and prevent slipping.
• If manufactured precisely it can help in mitigating roadway noise.
• It can provide more grip on a soft or loose surface.
Another major product Continental invented was detachable wheel tire that was made for touring vehicles (1905). In the late 1920s, Continental merged with several other major rubber industry companies to form the largest rubber company in Germany “Continental Gummi-Werke AG”.
Continental sells tires for automobiles, motorcycles, and bicycles worldwide under the Continental brand. It also produces and sells other brands with more select distribution such as Viking (limited global presence), General (US/Canada), Gislaved (Canada, Spain, Nordic Markets), Semperit (industrial applications), Euzkadi (Mexico/Latin America) and Barum to serve EU & Russia.
