1. A vehicle tire pressure control system, comprising:
- a road sensor configured to acquire road data regarding a road at an advanced location ahead of a current location of a vehicle;
a pressure regulator configured to control the air pressure within a tire of the vehicle during operation of the vehicle; and
a controller configured to determine a target pressure for the tire based on the road data corresponding to the advanced location, and control operation of the pressure regulator based on the target pressure and the advanced location such that the air pressure of the tire is at the target pressure before the vehicle arrives at the advanced location.
