What kind of rubber are car tires made of?

Car tires are primarily made from a combination of natural rubber and synthetic rubber, such as styrene-butadiene rubber (SBR). These materials provide durability, flexibility, and resistance to wear and temperature extremes. Additionally, tires often include reinforcing materials like fabric and steel belts to enhance strength and performance. Various additives, such as carbon black and silica, are also incorporated to improve grip and longevity.
