Tires may seem simple but their manufacturing process isn’t. The making of tires requires up to 30 various kinds of rubber, fillers and other ingredients that make a tire the perfection it is. Every ingredient is essential to the role of the tire as it affects safety, performance, fuel economy and eco-friendliness. The components that are used to make a tire fall roughly into 5 groups:
Natural rubber: tread layers’ main component
Synthetic rubber” part of the treads of a car
Silica and carbon black: used an a reinforcement to improve the durability of the tires
Metallic and textile reinforcement cables: also known as the “skeleton” of the tire, providing rigidity and geometric shape
Different chemical agents: usually used for unique properties like ultra-high grip or low rolling resistance.
All of these ingredients are mixed in big blenders to create a black, gummy compound that is then sent on for milling. Check out the video below to see the entire process!
