Tire monitoring arrangement including at least one tire condition sensor arranged on the tire to measure a condition of the tire and an energy generating mechanism or device arranged on the tread of the tire for generating electricity upon rotation of the tire. The energy generating mechanism is connected in a circuit with each tire condition sensor and powers the circuit and thus provides energy for the tire condition sensor(s). The tire condition sensor(s) and energy generating mechanism may be part of a tire monitor assembly which is affixed to an interior surface of the tire opposite the tread or inserted into the tire opposite the tread. Various tire condition sensors may be used including accelerometers, tire pressure sensors and tire temperature sensors. Various energy generating mechanisms may be used including a piezoelectric device, a polyvinylidene fluoride (PVDF) piezoelectric polymer, and a flexible material whose flexure causes energy generation.
