Tyre Pressure Monitoring System (TPMS) – Ensuring Driver Safety

WHAT IS TPMS?

TPMS stands for Tyre Pressure Monitoring System.

The primary purpose of TPMS in your vehicle is to alert you when there is a considerable loss in air pressure in one or more tyres, possibly creating unsafe driving conditions.

IMPORTANCE OF TPMS:

• Ensures Safety: Under-inflated tyres or improper tyre pressure is a significant cause of tyre failures leading to numerous accidents on the road.
• Ease of Use: Before the advent of this technology, the only way to know if the tyre pressure had reached an unsafe level was to step out and use a tyre gauge. It might sound easy for cars but immensely time-consuming and cumbersome for multi-axle long haul vehicles such as lorries and trucks.

DIRECT V. INDIRECT TPMS: HOW DO TPMS SENSORS WORK?

When it comes to accuracy, Direct TPMS is miles ahead. Here’s how it works:

1. It uses pressure sensors within each tyre to measure specific pressure levels.
2. Sensors in a Direct TPMS take it a step ahead by providing tyre temperature readings, thus increasing accuracy.
3. The compiled data is then sent to a centralised control unit for analysis and interpretation.
4. If the tyre pressure is lower than the standard level, an indicator on the dashboard illuminates, alerting the driver.

Indirect TPMS counts on wheel speed sensors – a part of the Anti-Lock Braking System. Here’s how it works:

1. The sensors in the ABS measure each wheel’s revolution rate.
2. The onboard computer then proceeds to compare it with other wheels.
3. This data is further used to assess the relative size of each tyre.
4. When a wheel starts to spin faster than it should, the computer points out the under-inflated tyre and warns the driver.
   

   IMPORTANCE OF TPMS IN RUN-FLAT TYRES

   Run-Flat Tyres are designed to function even after a puncture so that you can drive to a workshop to get it fixed or replaced.

   Though the specifications vary from brand to brand, RFT Tyres can operate up to 80 km at a maximum speed of 80 km/hr even if the tyre is deflated.

   When it comes to conventional tyres, a flat has to be replaced right away, even if you’re on a bustling road; putting you in a dangerous situation. On the other hand, RFT Tyres are fundamentally designed to keep the driver and passengers safe.

   Although RFT Tyres ensure safety, you might not know when you’re driving on an under-inflated Tyre. TPMS comes in as a mandatory layer of protection, making the entire mechanism trouble-free.

   • TPMS alerts you the moment a Tyre is under-inflated.
   • You keep the speed below 80 km/hr, reach a safe spot (within 80 km) and fix it.

DRIVER SAFETY IS OF PARAMOUNT IMPORTANCE

To ensure precision and compatibility with your vehicle during the installation or replacement of TPMS Systems, the need for a knowledgeable and experienced technician is mandatory.

Our highly skilled teams at Saeedi Pro outlets all across Dubai understand the gravity of Driver Safety and strive to ensure the same with Top-Quality Service.

Visit your nearest Saeedi Pro outlet to get the TPMS diagnosed, installed, programmed and re-learnt as per the need.

Frequently Asked Questions(FAQs) on TPMS:

Do I need to replace TPMS when replacing tyres?

Indirect TPMS doesn’t need replacement when replacing tyres as it functions on the data provided by the ABS. And even if your vehicle has a Direct TPMS installed, it doesn’t mean you have to replace it every time you get new tyres. Just make sure that the sensors are functioning. Our expert technicians at Saeedi Pro outlets will help you understand the current condition and offer an appropriate solution.

How do TPMS sensors get power?

Direct TPMS Sensors are usually powered by 3-volt Lithium-Ion batteries, which may last up to 5 years.

Can TPMS Sensors be re-used?

Yes, provided that the Sensors aren’t too old and in good operating condition. 

Why is the TPMS light on, but tyres are fine?

If you encounter this problem, the first step is to reset the system by simply pressing a button. If the light turns off, you’re good to go. If not, there’s a chance that one of the sensors might be damaged and needs replacement. Also, cold weather tends to lower the tyre pressure, so it’s best to drive your vehicle, let them warm up and check again.
