We can move from one place to another just because of the invention of wheels. Therefore, this invention is an excellent gift to humankind from our ancestors. The history is modern tyres is quite exciting, and it begins with the cycle tyre with a layer of rubber that is initially added to the wheels to reduce wear and tear.
New Nankang tyres had leather bands around a wheel that was made of wood.
The revolution in the tyres making process started after the discovery of vulcanisation. Vulcanisation is a critical tyre manufacturing process that converts the rubber from a sticky material into a material that is perfect for making tyres. Tyre industry witnessed its golden when the production of air-filled tyres started. These pneumatic tyres are made to improve traction on the roads.
Nowadays, the tyres are made with both natural and synthetic rubber, and these tyres are used in a variety of vehicles like bicycles, motorcycles, trucks, buses, tractors, cars, and sports vehicles.
A brief description of the tyre manufacturing process
The most critical materials used in making tyres are natural rubber, synthetic rubber, oil and carbon black. Natural rubber is obtained from rubber trees as a natural resource, and it is nearly half of the total rubber material used in the tyres. Carbon black is another common substance that provides the tyre black colour. Oil is also used in tyre manufacturing as a filler substance. Moreover, the tyre making process uses various protective agents and booster chemicals.
In this phase, all the raw materials are combined. After that, these mixed materials are heated at a temperature of nearly 120 degrees. The consistency of the rubber material is not the same in all the parts of a tyre. Furthermore, the manufacturers vary the consistency of materials just according to the objectives of making the tyre. For example, rubber material would be used differently in all-season tyres and winter tyres.
Making of different tyre components
Various components are used in the tyres, such as cables, belts, plies etc. All these components are added to the tyre to do different functions.
Assembly and vulcanisation
After all the components are ready, these are assembled with the help of an assembly machine to build the shape of a green tyre. These green car tyres are vulcanised with the help of high steam pressure that presses the green tyre against the tread pattern and side texts, this process provides the final appearance to the tyre.
Each tyre produced with the tyre making process is examined visually and also with the help of a machine. Visual inspection is performed to detect faults or defects in the final appearance of the tyre—the machine deal with the issues like radial throw, lateral force variation etc.
When the tyre clears the final testing process, it is ready to deliver and sent to the warehouse as a final product.
Nowadays, the scope of the tyres industry is widened with the help of consistent research and development.
A lot of types of tyres are available in the market, and each category has further plenty of different products made by leading manufacturers.
Usually, two main categories of tyres are passenger tyres, and SUV & truck tyres and each category is further divided into different types of tyres.
Passengers tyres may include the following types.
All-season tyres-made for the drivers who wish to use a single set of tyre year-round
Summer tyres- these tyres are designed for dry traction in the summer season
Winter tyres – these tyres serve you during the winter season
Touring tyres – tyres makers manufacture these tyres to provide a comfortable drive
SUV and truck tyres have the following types
SUV and Truck Tyres
Highway tyres – made for heavier loads
All-terrain tyres – often used four-wheel-drive vehicles
Mud-terrain tyres – these tyres are specially designed for mud and soil
As you see, the process of making car tyres is complex because car makers have to meet the expectations of their customers.
The tyre making process is going to improve more with the help of constant technological advancements.
