Title: Wheel balancer with pressure adjustment

Abstract: A wheel balancing system for the reduction of vehicle wheel and pneumatic tire assembly vibrations with the capacity to determine and selectively adjust the pneumatic tire's pressure simultaneously with wheel balancing. The balancing system includes a drive for rotating the tire and wheel assembly; a sensing system for the selective determination of vibration causation and correction information; a pneumatic system for the adjustment of the pneumatic tire's pressure; a control system for instituting the determined vibration corrections and pressure adjustments; as well as a communication system for receiving, transmitting and presenting data or instructions. The sensing system is responsive to the wheel balancing systems operational status, the wheel and tire assembly's operational status, wireless or network communications and input from the user. The control system includes automatic provisions for safety, convenience, time efficiency, balancing and pressure adjustment. The pneumatic system, under direction of the control system, institutes an automatic adjustment of the tire's pressure; and the communication system includes notification and display provisions.
