Facts About Tires: How Are Tires Made?

How are tires made? Know Facts About Tires

Most automobile tires are pneumatic, which means tires compress the air inside them. Pneumatic tires used to have an inner tube to maintain the air pressure. However, here’s a trivial fact about tires: these days’ engineers develop them to create a pressure seal with the wheel’s rim. You can learn more about them when you buy car accessories online

Tire manufacturing companies develop over 250 million new tires annually in vast, effective plants with experienced labour. Although much of the production process follows automation, skilled laborers must combine the tire parts. Additionally, it’s worth mentioning that there has been a massive rise in demand for tire inflators for cars online. 

Raw Materials

Engineers today use both natural and synthetic rubber to make tires, their primary raw material. The bark of Hevea brasiliensis, the rubber tree, contains a milky liquid that is natural rubber.

Engineers use acids with liquid latex to cause the rubber to harden, resulting in the raw rubber utilised in tire manufacture. You can form rubber into sheets by pressing extra water out of it. They dry these sheets in high smokehouses, compacted into sizable bales, before reaching tire plants worldwide. Crude oil contains polymers that tire makers use to make synthetic rubber.

Carbon black is the other main component of tire rubber. When you put insufficient oxygen on natural gas or crude oil, incomplete combustion occurs, producing a significant amount of fine soot and carbon black, a fine, soft powder. 

Tire manufacture requires so much carbon black that tire makers transport it on rail carriages. This is all the while storing it in enormous silos at the tire factory until needed.

Additionally, tires contain compounds such as sulphur. When you combine specialised chemicals with rubber and heat, the resulting tires have particular properties. This includes high friction for racing tires or high mileage (but lower friction) for passenger car tires. Furthermore, while forming into a tire, some compounds keep rubber flexible, while others shield it from the sun’s UV rays.


The tire tread is the raised pattern that remains in contact with the road. The body supports the tread and shapes the tire in a certain way. The beads are bundles of metal wire wrapped in rubber that keep the tire attached to the wheel.

Tire design today heavily relies on computers. With sophisticated analysis software and years’ worth of test data, tire experts can simulate the performance of other design elements. For example, the program generates a colour representation in three dimensions of a potential tire design. Furthermore, it computes the effects of various stresses on the suggested tire design.

Engineers often use computer simulations to study the impacts of various rubber compounds and experiments on tread design and tire body architecture. You can employ twenty varieties of rubber in different areas of a modern passenger automobile tire. 

The engineers carry out the production of tire prototypes for testing in collaboration with the designers. At this point, computer models of a new tire provide them with gratification. As a result, tire companies produce new tires in large quantities once design and manufacturing experts are happy with the design.

The Manufacturing Process

A tire-forming machine wraps many layers of carefully prepared rubber around a metal drum to create passenger car tires. Next, they bring the various tire sections to the forming machine, where an experienced assembler cuts and arranges the strips to create the different tire parts. They go by the title of “green tire.” 

The metal drum collapses when a green tire is complete. This enables the tire installer to remove the tire. After that, they place the green tire in a mould to cure.

Creating the rubber compound by combining the essential components is the first stage in the tire manufacturing process. Next, you store various recipes in computer control systems, which can automatically measure exact quantities of chemicals and rubber for a given recipe’s mixing. 

Finally, a third step involves running the mixture through a mixer to include more chemicals and create the “final mix.”

You bring the batch under heat and friction throughout the three mixing steps to soften the rubber and equally distribute the chemicals. Each batch’s chemical composition is unique to the tire component from its source.

The Future

Engineers are now developing innovative new tires all the time, thanks to advancements in tire design and rubber chemistry. This is to provide better performance in adverse weather conditions and higher mileage. 

As a result, tires with an 80,000-mile lifespan are now available from manufacturers. In addition, computer-aided design and testing have added notable asymmetrical bands to treads for increased traction and security on icy or snowy surfaces.

Additionally, tire design engineers test non-pneumatic tires. They can never run flat because they don’t have air inside them. A single slab of heavy plastic affixed to the wheel rim is all that makes up one of these non-pneumatic tires.

The plastic rim that extends outward from the tire has a rubber tread connected to it. So it may make contact with the road. Because there is more tread area in touch with the road, this tire has lower rolling resistance. This improves fuel efficiency and handling.
