Why is maintaining proper tire pressure important for fire apparatus?

Maintaining proper tire pressure is critically important for fire apparatus because it directly impacts both vehicle safety and fuel efficiency. When tire pressure is at the recommended levels, it ensures optimal contact between the tires and the road surface, which enhances handling, braking, and overall stability. This is particularly crucial for fire apparatus, which often carries heavy equipment and may respond to emergencies at high speeds.

Properly inflated tires also contribute to better fuel efficiency. Under- or over-inflated tires can lead to increased rolling resistance, which in turn requires more energy (fuel) to move the vehicle. Consequently, maintaining the correct tire pressure not only ensures the safety of the crew and the apparatus but also helps in conserving fuel, which is vital for operational costs and effective response times.

The other factors related to tire maintenance, while important, do not capture the primary safety and efficiency concerns associated with tire pressure.
