What impact can improper tire pressure have on a vehicle?

Improper tire pressure can lead to poor handling of a vehicle, which is critical for maintaining control, especially in emergency situations as often experienced by fire service vehicle operators. When tires are under-inflated or over-inflated, the contact area with the road changes, affecting traction and stability. This results in diminished performance when steering or braking, increasing the risk of losing control of the vehicle.

In under-inflated tires, the flexibility increases, causing more surface area to meet the road and potentially leading to overheating and blowouts. Conversely, over-inflated tires can result in a smaller contact patch with the road, which reduces grip and responsiveness. Both conditions can critically compromise the vehicle’s handling characteristics, affecting the vehicle's ability to navigate safely during operational duties, such as responding to emergencies or navigating through difficult terrain.

Overall, maintaining proper tire pressure is essential for vehicle safety and efficiency, making it imperative for fire service personnel to regularly inspect and adjust tire pressure as needed.
