Many kinds of rubber are used, the most common being styrene-butadiene copolymer.

Forecasts for the global automotive tire market indicate continued growth through 2027. Estimates put the value of worldwide sales volume around $126 billion in 2022, it is expected to reach the value of over $176 billion by 2027. Production of tires is also experiencing growth. In 2015, the US manufactured almost 170 million tires. Over 2.5 billion tires are manufactured annually, making the tire industry a major consumer of natural rubber. It is estimated that by 2019, 3 billion tires will be to be sold globally every year. Estimates put worldwide tire production of 2,268 million in 2021 and is predicted to reach 2,665 million tires by 2027.
