Why is natural rubber useful in tires for trucks, buses, racing cars, and airplanes?

Natural rubber is highly valued for use in tires for heavy-duty and high-performance vehicles—such as trucks, buses, racing cars, and airplanes—primarily due to its exceptional resistance to heat buildup.12

When vehicles operate under heavy loads or at high speeds, the constant flexing of the tire material generates significant internal heat. Natural rubber’s ability to withstand this heat helps maintain the structural integrity of the tire, preventing premature failure during demanding operations.12

In tire manufacturing, natural rubber is often blended with other materials to optimize performance. For example, sidewall formulations frequently combine natural rubber with butadiene rubber and carbon black to balance heat resistance with abrasion resistance and durability. Through the process of vulcanization, these rubber compounds are transformed into a durable, elastic solid capable of enduring the rigorous conditions required for safe and efficient transportation.21
