Tires found on automobiles, constitute a rubber casing over the rim of a wheel, entailing a gripping surface for traction and contribute as a cushion for the wheels of a moving vehicle. Tires in respect of most of the vehicles are found to be pneumatic, where air is put under pressure inside the tire. Normally pneumatic tires contain an inner tube to maintain air pressure; however, presently they are designed in order to form a pressure seal with the rim of the wheel. The pneumatic tire with an inner tube was invented by Robert Thomson in 1845, however, it was not popular until its reinvention by John Boyd Dunlop in 1880s, Natural rubber constitute the prime element in the manufacturing process of tires, irrespective of the fact that synthetic rubber is also applied. So as to strike a balance among strength, resiliency and wear resistance, the rubber is required to be treated with a variety of chemicals and then heated. Charles Goodyear, an American inventor could find out the process of strengthening rubber through vulcanization or curing, taking clue, when during his experiment the mixture of India rubber and sulfur dropped on a hot stove forming a hard lump. Presently, large efficient factories having skilled personnel generate over 250 million new tires every year. Irrespective of the fact that automation controls most of the steps in manufacturing process, skilled personnel are still necessitated to assemble the parts of a tire. (Tire Production Info)
             The manufacturing process of the tire involves several steps. The Rubber Compound Mixing operation is the considered to be first step in the manufacturing process of automobile tires. The process further involves preparation of "Fabric/Steel Cord Preparation; Belt and Ply Calendaring; Inner-line Calendaring; Bread Component Preparation; Tire Tread and Sidewall Extrusion Operations; Tire Tread Extrusion; Tire Sidewall Extrusion; Tire Building; Tire Curing and finally, the tir...
