A Lot to Learn about Car Tyres

Tyres are used to ensure the car has a smooth connection with the surface of the road. They are installed on the wheel’s outer edge. The vehicle’s performance is also affected by it. Made of rubber, tyres are filled with air pressure at levels recommended by the manufacturer. Air helps in acting as a buffer letting the tyres absorb any shock experience while driving on the road. It also minimises any friction with the road.

Tyre Construction

Tyres might appear to be sturdy and simple disks of rubber. However, there is a lot more detail to it. The process of engineering that goes behind it is very complicated with many layers and compounds that function together to make the car tyre function in the manner it does.

Design of Tyres

A different set of tyres operate differently. This is due to the variety of tyre designs. Each of them performs separate functions. There are mainly classified as off-road, heavy-duty, passenger car tyres, and many others.

A lot depends on the operating circumstances and the load, the elements in the tyre may be different. In comparison to passenger car tyres, heavier vehicle tyres contain extra layers of the belt, ply, breakers, or a weighty sidewall. Tyres are also designed according to the specific requirements of every vehicle manufacturer and for every car model.

Components and Materials

Apart from rubber, there are many other compounds that a tyre is made of. Natural and synthetic rubber is often the base material used to create a tyre. In addition to these, silica, carbon black, sulfur, oils, antioxidants, and many other elements are mixed as fillers. This part is covered when the process of mixing takes place to manufacture the sheets. In terms of the other elements, the bead is formed by covering the steel wire in rubber. It is fixed to the apex. The steel wires that are angles are utilised as breakers in tyres Bracknell

Assembling of Tyres

At first, the tyre’s carcass is assembled. The apex and bead are connected with the liner inside and the layers of body ply, and eventually with the tyre’s sidewall.

On a separate assembly, there would be a belt drum. In this case, the belt comes together, grouping the ply with the help of breakers and placing the tread. The assembly of the belt is then taken to the carcass, where they are fixed together.

The last step of manufacturing is vulcanisation or cooking. The green car tyre is put down in a mould that is patterned. This pattern is then pressed down in the car tyre. With steam of high pressure inside, curing bladders made of rubber is put within the car tyre. This begins to expand in the closed mould. This procedure is carried out under increased temperature levels. For vehicles with heavy tyres, this may take a lot of time, but for passenger car tyres, it takes somewhere close to 15 minutes or so. The tyres once ready are removed and sent for being inspected for their quality.

Tyre Parts

  • Casing: This includes everything apart from the treads and steel belts.
  • Sidewall: This starts from the tread to the rim bead. There is a lot of information on the sidewall that includes the load index, speed rating, and size.
  • Tread: It has sipes and grooves that offer traction with the ground.
  • Tread Patterns: These are also referred to as grooves and they help in gripping the road.
  • Ply: These retain the shape of the tyre, make them resistant to wearing of the tread and also enhance their strength.
  • Belt: These are steel wires that add up to the tyre’s strength.
  • Beads: These behave like fasteners that enable the tyre to remain attached to the car’s wheel.
  • Shoulder: This part is between the tread and the tyre’s sidewall.


Hence, it is quite evident that there is a lot more complexity attached to Goodyear tyres Bracknell and manufacturers across the globe work incessantly to innovate better things to enhance the driving experience of the customers.
