Construction

Most people assume tyres 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 above. 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 tyres 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 general y speaking a larger sidewall tyre 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 tyre in all driving.

The bead is what secures the tyre to the rim. It?s 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 tyre needs to offer good heat dispersal and for this the tyre shoulder section plays its part. The shoulder is the edge of rubber on both sides.

The tyre 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 tyre and the rim.
