Pneumatic Tire Definition
The word "pneumatic" comes from the Greek word for "spirit" that is "pneuma" and means something that is filled with air. Most tires you utilize or see these days are more than likely pneumatic tires. In fact, most private motor vehicles and modern commercial transportation can not function without pneumatic tires.
Definition
Pneumatic tires as defined by Webster's on line dictionary are described as tires that are made from durable rubber, which hold compressed air. Any kind of tire that requires air pressure to hold its form is considered to be a pneumatic tire.
History
The invention of the pneumatic tire has been credited to Irish surgeon John Boyd Dunlop, who during the year 1888 developed the first practical pneumatic bicycle tire. During 1895, the Michelin brothers Edouard and Andre, the Michelin brothers were the very first to utilize pneumatic tires on a car during a race.
Identification
Pneumatic tires are made from numerous bands of plys or corded 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 casing or tire body.
Types
Tube tires are a kind of tire which needs a rubber inner tube to hold the air pressure. Bicycle tires, motorcycle tires on spoke rims and car tires and older bias ply truck use inner tubes. Tubeless tires have a stiff bead on the edges of the sidewall which creates an airtight seal with the wheel. This kind of tire does not need an inner tube.
Exceptions
The fact that pneumatic tires are able to be punctured and lose air pressure makes them unsuitable for specific applications. Tires tires utilized by the military, utilized on forklifts, tires utilized in construction are usually filled with resilient foam or made with solid rubber.
