Tires are the largest consumer of rubber materials, accounting for over 70% of global rubber consumption. Tires require rubber with high elasticity, low heat generation, and excellent wear resistance, while also needing to balance wet traction (safety) and low rolling resistance (energy efficiency). These mutually constraining performance requirements drive continuous progress in rubber materials science and technology.

• Natural Rubber (NR): Due to its high tensile strength, tear resistance, and low heat generation, it is widely used in the treads and high-load areas of truck and bus tires.

• Styrene-butadiene rubber (SBR): The most commonly used rubber for passenger car tire treads, it has excellent wear resistance and wet traction, and is often used in combination with butadiene rubber.

• Butadiene rubber (BR): It has extremely high elasticity and excellent wear resistance, effectively reducing rolling resistance, but its wet traction is slightly inferior. It is usually used in combination with SBR or NR to improve overall performance.

• Butyl rubber (IIR): Due to its extremely low air tightness, it is specifically used to manufacture the airtight layer of tire inner tubes or tubeless tires.

Currently, the tire industry is developing towards "green, safe, and intelligent" directions. Green tires significantly reduce rolling resistance by using new fillers such as highly dispersed silica, thereby reducing fuel consumption and carbon dioxide emissions. At the same time, high-end products such as run-flat tires and smart tires (with built-in sensors that monitor tire pressure and temperature in real time) are becoming increasingly popular.
