Abstract
A system is used with a pneumatic tire mounted on a wheel rim to keep the pneumatic tire from becoming underinflated. The first system includes a plurality of pumps attached circumferentially to the wheel rim, each pump having pump parameters, and a control valve for controlling inlet air into a tire cavity of the pneumatic tire. The control valve has valve parameters. The system predicts system performance under various configurations and conditions through use of the pump parameters and the valve parameters.
