What is the typical weight distribution percentage on the rear axle of a fire apparatus?

The typical weight distribution percentage on the rear axle of a fire apparatus is often around 66%. This is largely due to the design and operational requirements of these vehicles, which need to carry substantial equipment, such as hoses, ladders, and water tanks, that are typically mounted at the rear or towards the rear of the vehicle.

Having a higher weight distribution on the rear axle helps enhance traction and stability, especially when the vehicle is fully loaded or operating on various types of terrain. Fire apparatus must maneuver in emergency situations, requiring them to have a stable center of gravity to avoid tipping or losing control under heavy loads.

Weight distribution is crucial when considering the vehicle's overall performance, including braking, steering, and handling characteristics. Knowing that fire apparatus commonly experience diverse conditions helps to understand the importance of this specific weight distribution percentage and its role in maintaining safe operations during emergencies.
