When tires are under-inflated, they operate less efficiently, which significantly increases the risk of tire failure. As the tires flex more during operation due to lower pressure, they heat up faster and are more prone to blowouts or separations. This overheating can result in a fire, which is a serious hazard, especially if it occurs at high speeds or under heavy load conditions.

While other hazards associated with under-inflated tires exist, such as vehicle instability and increased braking distances, the most direct consequence of tire failure is the risk of fire. Proper tire maintenance, including regular pressure checks, is crucial for safe driving and to prevent these dangerous situations.
