Tire :
Tire is a ring-shaped vehicle component that covers the Wheel's Rims to protect it and enable better vehicle performance. Most tires, such as those for automobiles and bicycles, provide Traction between the vehicle and the road while providing a flexible cushion that absorbs shock.
How a Tire is Manufactured :
Tires are manufactured according to relatively standardized processes and machinery,the tire industry consumer of natural rubber. Tire factories start with bulk raw materials such as rubber. carbon black and chemicals and produce numerous specialized components that are assembled and cured. This article describes the components assembled to make a tire, the various materials used, the manufacturing processes and machinery
The tire is an assembly of numerous components that are built up on a drum and then cured in a press under heat and pressure. Heat facilitates a polymerization reaction that crosslinks rubber monomers to create long elastic.
Most people assume tires are just made from rubber and filled with air, very little they know about the complex structure and different materials used that make it up. The essential components are shown in the diagram below. We have given a brief description of these components and their function. Some components are apparent like the tread and sidewall however there others that are hidden. Nowadays tubes are a thing of the past and tires come with the tube like rubber fixed to the inside this is called the inner lining and shown in the picture above as inner liner. The sidewall helps makes it rigid and protects the carcass, this in turn improves the ride quality generally speaking a larger sidewall tire i.e. that his higher in profile is a lot more comfortable than a low-profile one as it has more flex in the sidewall and hence absorbs the road imperfections better.
The tread is the main contact part with the road, tread designs are different and they are evolving and improving. The objective is to create a tread design that will give better grip in all weather conditions and cope with the demands and stresses that are put on the tire in all driving.
The bead is what secures the tire to the rim. Its made up of a beaded wire and rubber core. This is part of the sidewall.
Steel wire or a textile fabric makes up belt, its main job is to reinforce the structure protecting it from impacts sustained on the road.
A tire needs to offer good heat dispersal and for this the tire shoulder section plays its part. The shoulder is the edge of rubber on both sides.
The tire carcass has to resist the stresses caused by constant pressure of the forces that occur in acceleration, braking and changing direction, for this the inner cord must support the weight and absorb impact.
The chafer protects the cord as it appears on the rim wheel the chafer is the lining between the tire and the rim.
