Abstract: Methods and systems for adjusting air pressure of one or more tires of a vehicle. The system includes one or more valves respectively corresponding to the one or more tires, each valve of the one or more valves configured to receive air for inflating a corresponding tire or release air for deflating the corresponding tire. The system includes an air regulation device configured to provide air to the one or more valves of the one or more tires via one or more respective air lines and provide air to one or more air suspension devices via the one or more respective air lines. The system includes an electronic control unit (ECU) configured to cause the one or more tires to inflate or deflate based on a tire air pressure configuration.
