Things You Need to Know About TPMS

TPMS has been in the industry ever since things started to get modernized in the automobile industry. Here’re a few things you must know about it.

New automobiles have a tyre-pressure monitoring system (TPMS) already installed. It mainly uses sensors to monitor tyre pressure and warn you with a dashboard symbol in case the pressure is low. Normally, the TPMS warning light doesn’t come on unless the tyre pressure is less than 25% that’s below manufacturer’s recommended tyre pressure. Perhaps that’s the reason why expert recommend you not use the TPMS warning light as a substitute for regularly checking the tyre pressure.

Recognize the Light. Don’t Ignore It

TPMS helps drivers keep up with the safety of their cars only if you can identify the light alongside being vigilant about checking tyre pressures. A study found that 42% of drivers are unable to notice the low tyre-pressure warning light and the same number of motorist admitted to rarely checking the tyre pressure. Of those, 21% said that they only inspect it visually rather than using a tyre pressure gauge.

Sometimes, it can be quite risky to rely totally on TPMS. Keep in mind! The underinflated tires flex more than adequately inflated ones creating heat. Excessive heat breaks down components as well as chemical bonds inside a tire. Perhaps that’s the reason why being vigilant about tire pressure is imperative, especially in hot summer and when vehicle speeds are high.

What to Do When the Light Comes On?

Check the pressure using the gauge on all the tires when the TPMS light illuminates. Only one of them might need air, but it’s a good habit to check all tires. In case you see the TPMS light flashing, it can be either due to malfunctioning or perhaps you’re using, and the car isn’t able to detect sensor of the original wheel.

Temperature also has a significant impact on tire pressure triggering the TPMS light. In winters, the tire pressure drops significantly, and the 10-degree drop results in the loss of about 1 psi. You must have noticed in the winter season after a cold night that when you start up the car, TPMS symbol illuminates and then shut off after a while.

TPMS Types

Generally, in TPMS, there’re two types you come across; Direct and indirect.

Indirect TPMS: It’s the lower cost system that doesn’t monitor air pressure. Rather, it uses the ABS antilock braking system’s wheel-speed sensor in order to detect that why one tire is rotating faster than others. That’s why it can’t be considered as the accurate, and you can’t expect the perfect results since there’s a huge margin of error in it.

Direct TPMS: it measures the actual tire pressure. The modern direct systems have a gauge mounted to the wheel and valve. That gauge sends signals to the car’s computer. If you’re wondering about how the data is interpreted & displayed in the car, it entirely depends upon whether it’s a low-line or high-line unit.

Be Your Own Monitor

Precisely, the TPMS is only meant to warn you of a puncture or an air leakage. So make sure you check the tire pressures monthly or have someone else check them regularly for you. So whether you have regular or premium car tyres in UAE, regularly checking the pressure is imperative.
