Car tires are round, black and made of rubber. Look closer, however, and you’ll see that the design of tires and the interaction of the various materials that go into making them are extremely complex. But for some time now, the material experts and tire engineers at Continental have been bringing about a silent revolution. By 2050 at the latest, all tires are to be made of sustainable materials. There is still a long way to go until then. But step by step, it is already becoming apparent which raw materials will find their way into tire construction in the future. These include waste products from agriculture – such as the ash from rice husks – rubber from dandelions, recycled rubber or PET bottles.
Already today, around 15 to 20 percent renewable or recycled materials are used in a standard passenger car tire from Continental. To further increase the proportion of sustainable materials and conserve valuable resources, Continental continuously analyzes and reviews all raw materials used in tire production.
