Functions

RFQ

A: What types of systems are being used now? How do they work? Which works the best?

B: The National Highway Traffic Safety Administration (NHTSA) provides vehicle manufacturers options with which they can comply with the law. One option is to install a direct tire pressure monitoring system that uses pressure sensors located in each wheel to directly measure the pressure in each tire and warns drivers when the air pressure in any of their tires drops at least 25% below the recommended cold tire inflation pressure identified on the vehicle placard. Another option is to install an indirect tire pressure monitoring system that would warn the driver when a single tire has lost at least 25% of its inflation pressure compared to other tires on the vehicle. While direct systems could offer more precise warning thresholds, indirect systems cannot offer the same information or accuracy.

A: IS THIS FEATURE REQUIRED BY LAW?

B: Yes; the federal government required all new cars to include this system starting in late 2007.

A: DOES THIS FEATURE LET ME KNOW IF MY TIRES ARE OVER-INFLATED?

B: Most do. However, some features only detect for under-inflation. Check your owner’s manual for information specific to your vehicle.

A: CAN TPMS SAVE ME MONEY?

B: Tire pressure monitoring systems have the potential to save you money directly and indirectly. According to information from AAA and Safercar.gov from May 2014:

*Properly inflated tires can save you as much as 11 cents per gallon on fuel.

*Proper tire maintenance such as balancing, rotating and inflation can improve mileage and extend the life of tires by up to 4,700 miles.

*Properly inflated tires can improve a car’s mileage per gallon.
