A system is disclosed for use with a pneumatic tire (10) mounted on a wheel rim (12) to keep the pneumatic tire (10) from becoming underinflated. The system comprises a plurality of pumps (18) attached circumferentially to a wheel rim (12), each pump (12) having pump parameters; and a control valve (22) for controlling inlet air into a tire cavity of the pneumatic tire (10), the control valve (22) having valve parameters. Also, a system and method is disclosed for modeling a pneumatic tire (10) mounted on a wheel rim (12) and a pumping mechanism (14) mounted on the wheel rim (12) to keep the pneumatic tire from becoming underinflated. The system comprises a plurality of pumps (14) attached circumferentially to a wheel rim (12), each pump (14) having pump parameters; and a control valve (22) for controlling inlet air into a tire cavity of the pneumatic tire (10), the control valve (22) having valve parameters, wherein the system is configured for predicting system performance under various configurations and conditions through use of the pump parameters and the valve parameters. |
