Step 1: Raise And Extract

The natural rubber and created from rubber trees in places like; Brazil, Malaysia, and Indonesia.
The rubber in car tires are extracted from rubber trees that are found in tropical, rainy areas.

Step 2: Process

The rubber is transported to a manufacturing plant and the rubber is then mixed with sulfur, bisphenol, or peroxide. It is then molded and heated to take its finally shape.

Step 3: Manufacture

The tires are sent to many places in order to be created. These places start the different raw material points and sent to the tire building machine. The tires are then tested at the end to make sure it is up to standard. Tires have layers that are put on to make it more durable.

Fun Facts

  1. For the first 25 years of the car, all tires were white. Zinc oxide was added to the rubber for strength, but had a side effect of making bright white tires.
  2. By the second decade of the 20st Century, researchers were looking for more ways to increase durability. Carbon black, a waste product of the petroleum industry, added longevity to the tire, but changed the color to black.
