Pneumatic Tire Definition
"Pneumatic" is a Greek term for "spirit". "Pneuma" means anything that is filled with air. Nearly all tires you utilize or see nowadays are more than likely pneumatic tires. Actually, the majority of private vehicles and modern commercial transportation could not work without using 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 which needs air pressure to hold its shape is considered to be a pneumatic tire.
History
John Boyd Dunlop, the Irish surgeon has been credited to inventing the pneumatic tire. He developed the first practical pneumatic bicycle tire during 1888. In the year 1895, the Michelin brothers Edouard and Andre, the Michelin brothers were the first to use pneumatic tires on a car during a race.
Identification
Pneumatic tires are made from numerous bands of corded or plys fabric. Plys are often coated with rubber which allows them to hold air pressure. Bias ply tires have the plys overlaid at a certain angle to the other layers. Radial tires have all plys laid at 90 degrees to the tire body or casing.
KInds
Tube tires are a kind of tire that requires a rubber inner tube in order to hold the air pressure. Motorcycle tires on spoke rims, bicycle tires and car tires and older bias ply truck use inner tubes. Tubeless tires have a stiff bead on the sidewall edges that forms an airtight seal with the wheel. This kind of tire does not require an inner tube.
Exceptions
The fact that pneumatic tires can be punctured and lose air pressure makes them unsuitable for specific applications. Tires tires used in construction, tires utilized by the military, utilized on forklifts are normally filled with resilient foam or constructed with solid rubber.
