A piezoelectric energy harvesting system for converting mechanical energy of a tire of a vehicle to electrical energy includes sets of piezoelectric beam assemblies, a tire electrical jack, a conductive bearing, and an electrical storage unit. The sets of piezoelectric beam assemblies are embedded in multiple layers of the tire of the vehicle and electrically connected in a parallel configuration. Each of the sets of the piezoelectric beam assemblies are electrically connected in a series configuration for converting mechanical strains into electrical energy. The tire electrical jack is mounted on a rim of the tire and receives the electrical energy generated by the sets of piezoelectric beam assemblies via output terminals. The conductive bearing transmits the electrical energy received by the tire electrical jack to the electrical storage unit, which filters, rectifies, adapts and stores the transmitted electrical energy for powering components of the vehicle.
