Under-inflated tires can significantly contribute to unsafe driving behavior and potentially lead to brake failure. When tires are under-inflated, they do not make proper contact with the road surface, which can lead to reduced traction. This can cause the driver to apply the brakes more forcefully or frequently than necessary, leading to overheating and degradation of the braking system. Furthermore, under-inflated tires can increase rolling resistance, placing additional strain on the vehicle’s braking components. The maintenance of tire pressure is crucial for the overall safety and performance of the bus. Properly inflated tires ensure optimal traction, handling, and control, which helps the driver operate the vehicle safely without unnecessarily straining the braking system.
