The Benefits of Tire Pressure Monitoring Systems

Table Of Contents


Tire Pressure Monitoring Systems (TPMS) offer several benefits to vehicle owners and operators. These systems are designed to monitor the air pressure in a vehicle's tires and provide warnings if the pressure drops below a certain threshold. Tire Pressure Monitoring Systems offer a range of benefits and play a crucial role in maintaining optimal tire pressure and promoting safer and more efficient driving.

But, before we get on the benefits, let’s learn more about the basic working principles and take a brief look at the history of this system.

What is a Tire Pressure Monitoring System and How Does It Work?

A Tire Pressure Monitoring System (TPMS) is a technology designed to monitor the air pressure in a vehicle's tires and provide real-time information to the driver about the tire pressure status. TPMS helps ensure that the tires are properly inflated, which is essential for safe driving, fuel efficiency, and overall vehicle performance.

There are two main types of TPMS - direct and indirect.

  • Direct TPMS: This type of TPMS uses sensors mounted inside each tire to directly measure the air pressure. These sensors typically consist of a pressure sensor, a temperature sensor, and a radio frequency (RF) transmitter. The sensors continuously monitor the tire pressure and temperature, transmitting this information wirelessly to a central control unit or receiver inside the vehicle. When a tire's pressure drops below a preset threshold or if there is a significant temperature change, the TPMS system alerts the driver through a dashboard warning light or message.
  • Indirect TPMS: This type of TPMS uses the vehicle's existing sensors, such as the wheel speed sensors in the anti-lock braking system (ABS), to indirectly monitor tire pressure. It relies on the fact that underinflated tires have a smaller rolling circumference and rotate at a slightly different speed compared to properly inflated tires. The system continuously compares the rotational speeds of the tires and detects any significant differences. If it detects a difference that suggests one or more tires are underinflated, it triggers a warning for the driver.

Here's how a typical direct TPMS works:

  • Sensor Installation: Small sensors are installed inside each tire, typically mounted on the rim or valve stem. These sensors consist of pressure and temperature sensors, along with an RF transmitter.
  • Data Transmission: The sensors continuously measure the air pressure and temperature of their respective tires. This data is then sent wirelessly to a central control unit or receiver in the vehicle.
  • Data Processing: The control unit processes the received data and compares it to the recommended tire pressure values provided by the vehicle manufacturer. It also considers temperature changes, as tire pressure can be affected by temperature fluctuations.
  • Alerts to Driver: If the control unit detects that a tire's pressure has dropped below a certain threshold, it activates a warning light on the dashboard or provides a message on the vehicle's display screen. The driver is alerted to the specific tire that needs attention.
  • Maintenance and Correction: The driver can then check and adjust the tire pressure as needed. Once the tire pressure is corrected, the TPMS system is reset, and the warning light should turn off.
