Raw Materials
More than 100 raw materials are used in the production of automobile tyres, including rubber, reinforcing agent, tyre cord, compounding ingredients and bead wire.
The tyre composition in weight varies depending on the tyre category, but approximately half consists of rubber (natural rubber 29% and synthetic rubber 18%), and the others are reinforcing agent at 25%, tyre cord at 13% and so on.
