Tire Pressure Monitoring Systems: All You Need to Know

Tires are virtually the only part in a vehicle that comes in direct contact with the road. Irrespective of whichever machine you are using, tires are essential in maintaining control on the road as well as delivering the performance you expect from the machine! Tires will only perform to their optimal capacity when they are in good shape and properly inflated!

How do you go about it?

Steering the car on normal roads and especially on steep bends, brake systems kicking in and saving you from an accident as well as handling the car is largely dependent on the tires and the condition they are in.

It is nearly impossible to detect the correct pressure in your tires by simply looking at them. There is a qualitative difference that can be felt while you drive; even then it is not enough to tell you If they are over-inflated or under-inflated. In times such as this, you want a professional to check your car/tires and make sure that it is in a good shape. The only problem is, you don’t always have the time or it is far away.

Tire Pressure Monitoring System (TPMS) steps in here; the idea is to give you warnings whenever your tires are in need of checkups! All cars produced after or in 2008 have been equipped with TPMS under certain acts passed by the government. It is important for us to know the hazards related with low tire pressure.

The engine is not able to perform as well and thus heats up pretty quickly. This also causes vehicles to become less fuel efficient and adds to the burden! Over – inflation leads to quicker damages on the road. It won’t be as resistant to pot-holes, rocky roads or bumps before giving way and making sure that your car and you suffer some damages!


  • The symbol representing TPMS is often a section of a tire alongside an exclamation point or a top view of a vehicle with four tires exposed. They light up to indicate when the air pressure inside your tires are acting up and is inadequate!
  • Because of a variety of considerations from tire companies and automakers, The TPMS warning light isn’t required to switch on till the tire pressure is 25 percent or below the percentage recommended by the manufacturer. This 25 percent mark is below the required level for driving safely, set by the American Automobile Association.
  • TPMS depend on Sensors directly in contact with the tires or some other part of the body. Direct Sensors such as the wireless ones placed in the tires to gauge the pressure and the Indirect ones that measure wheel rotations are both useful in reporting about the problem quickly! The systems are pre-placed with modules with a functional range of acceptable scenarios.
  • A TPMS constantly checks the air pressure in tires and warns the driver if any one of the tires has lower pressure than the required amount. There are systems that are capable of detecting too much pressure in the tires as well.

    As soon as the TPMS detects the presence of improper tire pressure even in a single tire, the indicator lights up on the dashboard.

What to do after the light comes on ?

Once the TPMS indicator is lit up in the dashboard, it does not mean that you have to jump out your vehicle that very instant; neither do you have to immediately pull over and stop the vehicle. Don’t worry, it simply means that the tires are running a little low and you have to get them checked and filled.

Make sure you test the pressure for every individual tire and see if any of the tires are providing incorrect readings. Work accordingly from there on out, according to the need either Inflate or deflate them. Proper tire pressure is mentioned and specified by the vehicle manufacturer. The best bet is to take your car to an automobile shop and get it tested again before letting them take the necessary steps.

The metric is specified on the car’s body as well as the manual it comes with. Keep that in mind and conduct your checks and solutions accordingly. There is no simple way to put it, but your car is really your sole responsibility.
