One of the important factors in ensuring driving safety is tire pressure. Improper tire pressure can cause many risks such as loss of control, accidents and rapid tire wear. To monitor and maintain tire pressure in a safe condition, tire pressure sensors have become a popular accessory installed in cars today.

What is tire pressure?

Car tire pressure is the pressure applied to the space inside the tire, measured in psi (pounds per square inch) or bar. It refers to the degree of compression of the air inside the tire and has a great influence on driving performance and safety.

Maintaining correct tire pressure is very important. When tire pressure is incorrect, problems such as:

  • Fuel consumption: When tire pressure is too low, the contact area between the tire and the road surface increases, increasing friction and unnecessary fuel consumption.
  • Loss of control: Improper tire pressure can cause loss of vehicle control and stability, especially when driving at high speeds or in emergency conditions.
  • Uneven tire wear: Uneven pressure across the tires can lead to uneven wear on the tire surface. This not only reduces tire life but also affects traction and safety.
  • Traffic accidents: Incorrect tire pressure can cause traffic accidents, especially in cases where the tire explodes or malfunctions while driving.

Therefore, it is important to regularly check and adjust tire pressure according to the vehicle manufacturer’s instructions. Maintaining correct tire pressure helps enhance driving performance, save fuel and ensure safety when participating in traffic.

What is a tire pressure sensor?

Car tire pressure sensors are an important component in the tire pressure monitoring system (TPMS – Tire Pressure Monitoring System). The main task of the tire pressure sensor is to measure and transmit information about the pressure of each tire to the TPMS system.

Tire pressure sensors are often mounted directly on the tire valve or can be built into the tire valve. When the tire is inflated to the correct pressure, the sensor will read and remember that pressure value. If the pressure drops below the safe threshold due to some reasons such as a punctured tire, the sensor will warn the TPMS system, through a warning light on the dashboard or a notification on the display screen.

  • Early warning: Tire pressure sensor helps detect tire pressure drops early, helping the driver know when to adjust pressure or check tires to avoid dangerous situations.
  • Enhanced safety: Monitoring tire pressure helps reduce the risk of traffic accidents caused by flat tires, explosions or loss of control due to incorrect pressure.
  • Energy saving: Correct tire pressure increases fuel efficiency and reduces unnecessary fuel consumption.
  • Tire protection: Monitoring tire pressure helps detect problems such as loose tires, holes or damaged tires early.
  • Tire maintenance: Tire pressure sensors help drivers monitor and maintain correct tire pressure, thereby helping to prolong tire life. This means reducing the cost of replacing new tires and saving time and effort on tire maintenance.
  • Convenient and easy to use: The tire pressure sensor is integrated into the car’s TPMS system, and the tire pressure information is displayed directly on the car’s dashboard or screen. Drivers can easily monitor and check tire pressure conveniently and quickly.

Should I install a tire pressure sensor?

The decision to install a tire pressure sensor or not depends on many factors and your personal preferences. However, according to many experts, using a tire pressure sensor will make your trip safer and more secure.

Therefore, if you focus on vehicle safety, you should install a tire pressure sensor.

Safe movement

Safe movement

Tire pressure sensors help you monitor and control tire pressure accurately. It can warn you when there is a slight change in tire pressure, helping you prevent dangerous situations caused by flat tires, explosions or loss of control. If you are particularly concerned about driving safety, installing a tire pressure sensor may be a reasonable choice.

Energy saving

Improper tire pressure can lead to increased fuel consumption due to unnecessary friction between the tire and the road surface. If you’re concerned about saving fuel and reducing your environmental impact, installing a tire pressure sensor can help you maintain correct tire pressure and save fuel.

Protect your tires

Monitoring tire pressure helps detect early problems such as punctured tires, loss of air or loose tires. This helps you make timely repairs or replace tires before serious damage occurs, keeping tires in good working condition and increasing their lifespan.

Create a comfortable driving experience

Drive comfortably

Driving with an overinflated tire combined with reaction forces from the terrain causes the vehicle to vibrate. This brings troubles when driving such as difficulty controlling the steering wheel and mental fatigue. Especially when you drive on rough roads with many potholes and potholes.

On the contrary, if you drive with a flat tire, the travel speed will slow down, causing the vehicle to lose speed, causing discomfort. Installing a pressure sensor in your car will no longer have to worry about that. Because just by glancing at the display screen, you can clearly grasp the condition of your tires.

Above all, the pressure sensor also helps the driver control the vehicle more accurately. At the same time, it helps avoid abnormal wear and tear of the suspension systems. For example, the suspension system and chassis system.

Easy maintenance

Tire pressure sensors help you easily monitor the tire pressure of each wheel. Checking and adjusting tire pressure becomes simpler and more convenient, without the need to use a separate pressure measuring device.

Should the tire pressure sensor be installed inside or outside?

Internal tire pressure sensor

Internal tire pressure sensors are sensors mounted inside the tire, with the tire’s regular valve replaced by a sensor valve.

Internal tire pressure sensor

– Advantage

+ With this type of sensor, because it is mounted inside the tire, you will not have to worry about the sensor being stolen.

+ High aesthetics because it is hidden inside the tire

+ High battery life: average 3-5 years

+ High durability due to no contact with the environment, no impact with the outside environment

+ Ensure highly accurate parameters

– Defect

+ Because it is mounted inside, installing and repairing this type of sensor is quite difficult.

External tire pressure sensor

+ External tire pressure sensors are sensors mounted on the outside of the tire, specifically at the valve tip of the tire.

External tire pressure sensor


+ With this type of sensor, you can easily install and repair without having to remove the tire. With this design, you can easily replace the sensor in case of malfunction or damage.

– Defect:

+ Because it is mounted on the outside, this type of sensor is more susceptible to theft.

+ Low lifespan, if you want to use it for a long time, you have to replace it many times

+ Low aesthetics due to being mounted on the outside

In general, each type has its own advantages. But for convenience and optimization according to many customers and car enthusiasts, it is eliminated Internal valve tire pressure sensor Most popular because of its high average lifespan and absolute safety.

How much does a tire pressure sensor cost?

Currently, on the market there are many types of internal tire pressure sensors, ranging from 1.5-3 million VND depending on the type. However, to buy products at reasonable, accurate and reputable prices, Caron is a brand that is highly appreciated for its quality and the most affordable price among many current categories.
