Passenger safety is a major focus of all automotive designs, supported by ongoing efforts to continually enhance safety-related features. One such feature is the tire-pressure monitoring system (TPMS), which provides either real-time pressure readings or under-pressure warning indicators to the driver within the comfort of the vehicle cabin. Studies have shown it is common to find vehicles traveling with under-inflated tires. This condition has unwanted side effects: additional stress on the steering system, accelerated tire wear and decreased fuel economy. Unfortunately, it also has some very sobering consequences: Statistics show that more than 400 fatal and up to 10,000 non-fatal accidents per year are caused by flat tires or blowouts. Twenty percent of flat tires and blowouts are the result of under-inflated tires.
