What is one of the primary causes of tire fires in vehicles?

One of the primary causes of tire fires in vehicles is under-inflated tires. When tires are under-inflated, they experience increased flexing while in motion, which generates excessive heat. This heat can lead to deterioration of the tire materials and, in worst-case scenarios, can ignite flammable components within or around the tire. The low pressure also means that the tire cannot properly support the weight of the vehicle, which can further exacerbate the situation by creating more friction and generating heat. Maintaining proper tire inflation is crucial not only for vehicle performance and safety but also for preventing dangerous conditions like tire fires.
