The term "pneumatic" comes from the Greek word for "spirit" that is "pneuma" and means something which is filled with air. Most tires you utilize or see nowadays are more than likely pneumatic tires. Actually, nearly all private vehicles and modern commercial transportation could not function without using pneumatic tires. Pneumatic tires as defined by Webster's online dictionary are described as tires that are constructed from durable rubber, which hold compressed air. Any kind of tire that needs air pressure to hold its form is considered to be a pneumatic tire. The Irish surgeon John Boyd Dunlop has been credited to inventing the pneumatic tire. He developed the first practical pneumatic bicycle tire in the year 1888. During the year 1895, the Michelin brothers Édouard and André, the Michelin brothers were the first to utilize pneumatic tires on a car during a race. Pneumatic tires are made from numerous bands of corded or plys fabric. Plys are normally coated with rubber that allows them to hold air pressure. Bias ply tires have the plys overlaid at a particular angle to the other layers. Radial tires have all plys laid at 90 degrees to the tire body or casing. Tube tires are a type of tire that requires a rubber inner tube so as to hold the air pressure. Motorcycle tires on spoke rims, bicycle tires and older bias ply truck and car tires utilize inner tubes. Tubeless tires have a stiff bead on the sidewall edges that forms an airtight seal with the wheel. This eliminates the need for an inner tube.
