Understanding the tyre manufactory process
Do you know how your tyres are made, or what happens to them after use?
Read on below to learn about the lifecycle of a tyre, from factory, to store, to your car and beyond.
How tyres are made
The manufacturing journey of a tyre starts in a factory, where individual materials are combined to make the many components of a tyre, and then assembled and cured to create the finished product.
Mixing:
The first step in the creation of a tyre is the mixing process, where up to 30 different kinds of ingredients are combined to create a thick black compound. Materials mixed can include natural rubber, which is sourced from rubber trees in plantations, synthetic rubber, carbon black, sulphur and other chemical agents. The resulting rubber is formed into sheet strips for the next stage of mixing.
Extruding:
This rubber is mixed further, heated and then extruded and cut into lengths forming tread and sidewalls.
Carcass Construction:
Fabric is weaved into cords, coated with rubber and cut to lengths forming the carcass ply material.
Steel Belt Production:
Individual steel cord filaments are wound together, coated with rubber and cut to lengths forming the steel belts.
Bead Manufacture:
Individual steel cord filaments are wound in a circle and coated with rubber forming the beads.
Building:
The tyre components, comprising of the rubber tread and sidewalls, steel belts, carcass ply and beads are assembled on an automated machine. The end result is a “green tyre,” that does not yet have the grooved pattern of tread.
Curing:
All components are vulcanised together in a mould, which shapes the ‘green tyre’ into its final state, creating the sidewall markings and tread pattern.
Inspecting:
The last step in the tyre manufacturing process is the careful inspection of the tyre, both by trained inspectors and specialised machines, to ensure the tyres are free of faults and ready to go on the road.
We source our tyres from a variety of factories internationally, for our network of stores around Australia.
Your tyres in action
The next stage in a tyre’s lifecycle is the time it spends on your car. To get the most value from your tyres, it’s important you look after them. Tyres that aren’t maintained will wear more rapidly, cause the vehicle to expend more fuel, and can compromise your vehicle’s braking and handling characteristics. Regular maintenance will make sure your tyres are safe to drive for longer, and save you additional trouble down the line.

What happens to your old tyres once you’re done with them?
As part of our environmental commitment, we’re focused on responsible disposal and the sustainable management of your old, end-of-life tyres.
Some uses for end-of-life tyres are:-
Athletic and racing tracks
Bridgestone Athletics Centre in South Australia. -
Commercial flooring
used in many of our Bridgestone stores. - Road surfacing and reinforced concrete
- Playground soft fall surfaces and non-slip mats
We give truck tyres a new life too.
Our local manufacturing of Bandag tyre tread enables us to give new life to used truck tyres. We recycle the casing by retreading it, a process which can be repeated multiple times.
Bandag retreading uses less raw materials, oil, water and energy compared to the production of a new truck tyre.
Why do you pay to recycle or repurpose your old tyres?
Used tyres are still a waste product, and it costs more to recycle or repurpose them responsibly and sustainably. Bridgestone works with Tyre Stewardship Australia (TSA) to invest in research and development into more sustainable uses of old tyres, with the vision of making them a valuable resource in the future.
