Which factor can contribute to tire fires?

Under-inflation of tires is a significant factor that can contribute to tire fires. When tires are under-inflated, they flex more than they should during use, generating excessive heat due to increased friction with the road surface. This unnecessary heat buildup can cause the tires to overheat, leading to a breakdown of the tire materials, and eventually, a fire.

Maintaining proper tire pressure is crucial for safe driving, as it not only helps in fuel efficiency but also prevents tire failure due to overheating. Regularly checking and adjusting tire pressures according to the manufacturer's specifications helps ensure tire longevity and reduces the risk of fire hazards.
