Natural rubber is a milky white fluid that comes from the sap of the rubber tree (Hevea brasiliensis). It is a renewable resource that can be grown on plantations. Natural rubber is used in tire treads because of its elasticity, strength, and durability.
2. Synthetic Rubber
Synthetic rubber is made from petroleum-based materials. It is a cheaper alternative to natural rubber, and it is often used in the sidewalls and inner liners of tires. Synthetic rubber is not as durable as natural rubber, but it provides improved resistance to heat and ozone.
3. Carbon Black
Carbon black is a pigment that is made from the burning of fossil fuels. It is used in tires to reinforce the rubber and improve its strength and durability. Carbon black also absorbs ultraviolet light, which protects the tire from damage caused by the sun.
4. Silica
Silica is a mineral that is used in some tires to improve their fuel efficiency and wet grip. Silica reduces the rolling resistance of the tire, which means that less energy is required to move the tire. Silica also helps to improve traction on wet roads.
5. Aramid
Aramid is a synthetic fiber that is used in some tires to reinforce the sidewalls and tread. Aramid is strong and lightweight, and it helps to protect the tire from punctures and blowouts.
6. Steel
Steel is used in tires to make the beads, which are the rings that hold the tire in place on the rim. Steel is also used in the construction of radial tires, which are designed to provide improved fuel efficiency and handling.
7. Polyester
Polyester is a synthetic fiber that is used in the construction of some tires. Polyester provides strength and durability, and it can help to improve the tire's resistance to heat and chemicals.
8. Other Materials
In addition to the above materials, tires may also contain other materials, such as nylon, cotton, and sulfur. These materials help to improve the performance and durability of the tire.
