What a waste!

Globally, under-inflated tires cause more than 20 million liters of fuel to be burned unnecessarily, 2 million tons of CO2 in the atmosphere and 200 million tires to be prematurely wasted.  Properly maintaining tire inflation offers significant savings in several areas. 

TRW Automotive offers both direct and indirect Tire Pressure Monitoring systems that address the ever-important safety and fuel-savings benefits.  The company's enhanced system uses a sensor, Electronic Control Unit (ECU)/receiver, four initiators and an interior display.
