Tire Pressure Monitoring System (TPMS) devices ensure tires and vehicles are operated safely under the recommended factory conditions. An under inflated tire could pose potential risks to a driver and other motorists. As of 2008, all new vehicles sold in the United States are required to have TPMS systems. The proliferation of TPMS systems in new vehicles is driving demand for workshops and garages to purchase TPMS tools. In addition, the lithium battery in most TPMS sensors typically have a 10 year shelf life - driving pent-up demand for replacements after a decade.
