A pneumatic tire is a round, rubber tire that is inflated with air. The most common example of pneumatic tires in everyday life is the tires on an automobile. The pneumatic tire can also be found on bicycles, wheelchairs and forklifts.
Historically, the spelling was tire and is of French origin, which comes from the word tirer, to pull. The reason for this naming is that originally tire referred to iron hoops or thick wires bound to carriage wheels.he bead is the part of the tire that contacts the rim on the wheel. The bead is typically reinforced with steel wire and compounded of high strength, low flexibility rubber. The bead seats tightly against the two rims on the wheel to ensure that a tubeless tire holds air without leakage.
