So why are tire pressure monitoring systems so important in your vehicle? Congress passed the TREAD Act, which requires most vehicles made after 2006 to be TPMS-equipped. By maintaining proper air pressure in your tires, the tires will last longer, you’ll have better braking and vehicle handling, and you’ll notice improved fuel efficiencies.
The TPMS alert systems indicates to the driver that one or more of the tires is underinflated. Often these sensors in the valve service kit last for around 5-7 years. Typically, when you are replacing a set of tires, the tire shop staff will recommend replacing the sensors at that time depending on the original age of the sensors. There isn’t a warning given as to when the sensors might need to be replaced and it’s cheaper to replace at the same time as your tires instead of a separate mount and dismount fee to install new sensors.
When you see the TPMS indicator lit on your dash, air up your tire to the recommended air pressure indicated on the placard inside the driver’s side door.
