A vehicle includes a sprung mass including a cabin coupled to a chassis, tractive assemblies engaging the chassis, each tractive assembly including a pair of tractive elements, gas springs coupling the tractive elements to the sprung mass, and a controller operatively coupled to pressure sensors. Each gas spring is configured to impart an upward force on the sprung mass. The upward force varies based on a pressure of a pressurized gas within a chamber of the gas spring. Each pressure sensor is configured to provide a signal indicative of the pressure of the pressurized gas within one of the chambers. The controller is configured to determine a weight of the sprung mass using the signals from the pressure sensors. The controller is configured to monitor at least one operational condition of the vehicle and determine whether or not to disable determination of the weight based on the operational condition.
