Pneumatic Tire Definition
"Pneumatic" is a Greek term for "spirit". "Pneuma" translates to anything which is filled with air. Nearly all tires you use or see today are more than likely pneumatic tires. In fact, most modern commercial transportation and private transportation could not work without utilizing pneumatic tires.

Definition
Pneumatic tires as defined by Webster's on-line dictionary are described as tires that are made from durable rubber, holding compressed air. Any tire which needs 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 in the year 1888 developed the very first practical pneumatic bicycle tire. During 1895, the Michelin brothers Edouard and Andre, the Michelin brothers were the very first ones 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 usually coated with rubber that enables them to hold air pressure. Bias ply tires have the plys overlaid at a specific angle to the other layers. Radial tires have all plys laid at 90 degrees to the casing or tire body.

KInds
In tube tires, there are a kind of rubber inner tube to hold the air pressure. Bicycle tires, motorcycle tires on spoke rims and older bias ply truck and car tires use 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.

Exceptions
The fact that pneumatic tires are able to lose air pressure and be punctured makes them unsuitable for specific applications. Tires tires used by the military, used on forklifts, tires used in construction are often filled with resilient foam or constructed with solid rubber.
