What is another cause of tire fires related to duals?

Dual tires that touch can indeed be a significant cause of tire fires. When dual tires come into contact, they generate friction due to the movement as the vehicle rolls and the imperfections in the road surface. This friction can cause heat to build up between the tires, especially if the tires are not properly inflated or aligned. Over time, this heat can increase to the point where it ignites the materials within the tires, leading to a fire.

Maintaining proper spacing between dual tires is crucial to minimize this risk. Additionally, keeping an eye on factors like tire inflation and road conditions can help prevent not only tire fires but also other tire-related issues.

While factors like low air pressure, dirt buildup, and worn-out tires can contribute to tire problems, they do not specifically relate to the scenario of dual tires touching, which directly creates conditions conducive to fire hazards.
