How Are Reliable Tyres Made?

Understanding the processes behind the tyre production process is helpful to you as a motorist, and will give you a better understanding of the way your vehicle interacts with the road surface.

Tyre Production

The first stage in the manufacturing process is the blending of raw materials to create the composite from which the tyre is made. These ingredients include various chemicals as well as up to thirty different types of rubber, used in different combinations. These are placed under high heat and pressure in devices called Banbury machines, which makes a sticky black gum.

The gummy compounds are cut into thick slabs and then put through a process known as milling. In this process, the gum is cut into different shapes and sizes to make up treads, sidewalls, and other components of a tyre. Then the construction of the tyre itself begins, in which various layers are pressed together to make what is known as a ‘green tyre’. In the final curing process, heated moulds give the tyre its final shape. The tyre is then ready to be fitted onto a car.

The Different Types of Tyres

There are two main types of tyres: those with air-filled tubes inside, and ‘tubeless’ tyres that hold the air between the rim and the wheel instead. Tubeless tyres are standard on most international cars.

Most mass-production cars come with standard tyres. This type of tyre is made of a hard rubber compound, and is designed to be used on a variety of road types and driving conditions.

Performance tyres are made of a softer rubber compound that adds grip on hot, dry roads, but can be dangerous if used on wet ones, particularly if the grip is worn down.

Off-road tyres have a greater surface area and deeper treads to maximize the amount of grip they provide. These tyres can wear out quickly on normal roads and at high speeds, however.
