Tire Pressure Monitoring System (TPMS)

Continuously monitor tire pressure in real-time

Fast facts

Advantages of tire pressure monitoring systems

  • The TPMS continuously monitors the tire inflation pressure, and alerts the driver if it falls below a certain level.
  • This safety feature also lowers your car's fuel consumption and CO2 emissions.
  • Tire performance characteristics are optimized and tire life is extended.

Driving safety and comfort are directly related to the long-term condition of your tires. If they're in poor condition, then it's only a matter of time before disaster strikes. Approximately 40 percent of all incidents of unexpected tire failure, for example, are caused by underinflated tires.

To address this problem, Continental has developed a tire-pressure monitoring system (TPMS) that works with wheel sensors and brake systems to alert the driver of low tire pressure levels via a car dashboard warning light.

The TPMS continuously and reliably monitors the inflation pressure in real-time. In the event of pressure loss below a safe threshold, it immediately alerts the driver to take action. When used correctly, the TPMS can enhance driving safety by eliminating a frequent cause of accidents.

Sounds pretty impressive, right? Well, that's not all. Another benefit of this invaluable safety feature is that it reduces your car's fuel consumption and CO2 emissions.

If a car's tires are underinflated by only 0.3 bar, for example, the vehicle consumes 1.5 percent more fuel – and produces a correspondingly higher amount of CO2 emissions.


There are many more advantages to a TPMS, including:

  • Optimizing tire performance characteristics, from braking performance to hydroplaning protection;
  • Extended tire life;
  • Speed-related warning signal;
  • Systems built with modular architecture for scalable functionality;
  • Compatible with a complete spectrum of Continental mechanical solutions.

State-of-the-art direct measurements with TPMS

Let's take a closer look at the inner workings of a tire-pressure monitoring system. How does it work?

Readings are taken directly from the tire. Battery-powered sensors mounted on the rim and integrated into the valve measure the tire pressure. This data is coded and transmitted in a high-frequency signal to a receiver. Dedicated software in the control device then processes the information and displays it on the dashboard of the vehicle.

In effect, thanks to these dedicated sensors, the driver now has complete oversight of tire pressure changes. And most importantly, they're warned before a critical situation arises.

TPMS software is so sophisticated that, after evaluating the collected data, it can calculate the rate of pressure leakage. Additional software functions are standardized warnings when approaching specific limits, an ongoing comparison of tire temperature, automatic tire identification, and checks on spare tires.

TPMS can even distinguish whether the vehicle is moving or standing still, and adjusts the frequency of the sensors accordingly. When a vehicle is moving, for example, tire pressure and tire temperature are monitored every few seconds, and TPMS delivers the readings continuously. If the vehicle is standing still, however, the TPMS takes measurements between longer intervals. The readings are only transmitted after a pressure change has been detected.

Statutory regulations in Europe for TPMS

The European Commission has passed a law which requires integrated tire-pressure monitoring systems on all new cars manufactured since 2014.

Many vehicles already include TPMS as standard equipment. These systems can also make their data available to other vehicle systems, e.g., the braking system. However, even if your vehicle does come equipped with a TPMS, it doesn't mean you should entirely stop conducting a manual tire pressure check now and then. Continental recommends checking the tire pressure once every two to four weeks as a routine precautionary measure.
