Mazda Tire Pressure Monitoring Sensor & Fastening Nut (TPMS) | Mazda CX-9 (2018-2023)

The tires on your Mazda help keep you rolling so you'll always be on the go. The tire pressure monitoring system (TPMS) in your Mazda works through sensors in your tires which will report real-time tire pressure. The system will alert you if the pressure inside your tires is lower than what is considered safe. This system helps keep you safe on the road, increases fuel economy (properly inflated tires leads to lower fuel consumption) and also helps you keep your tires maintained.
