What is a common cause of tire fires?

Underinflated tires and dual tires that touch are a common cause of tire fires due to several factors related to heat build-up and friction. When a tire is underinflated, it does not maintain proper contact with the road, which generates excessive flexing and heat as the tire rolls. This heat can cause the tire to deteriorate more quickly and may even lead to a blowout.

Additionally, when dual tires touch, the friction generated between them can create significant heat, especially if both tires are underinflated. This can cause the rubber to break down and may ignite, particularly if combined with other factors such as debris or a flammable substance nearby. Proper tire maintenance, such as ensuring correct inflation levels and checking alignment, is essential for preventing tire fires and enhancing overall vehicle safety.
