Abstract: The present invention relates to an automatic lift system for a pusher axle and/or a bridge axle of a truck. The automatic lift system raises the pusher axle and/or the bridge axle in the event of a tire blowout or low tire pressure to prevent the truck from swerving, spinning out or rolling over. The system includes a tire pressure sensor integrated to each of two wheels connected to the pusher axle and each of the two wheels connected to the bridge axle. Each tire pressure sensor is connected to a wired circuit and controller area network (CAN) of the truck for electronic communication with a control box. The control box receives tire pressure information from the sensors and transmits axle lift instructions in response to the tire pressure.
