Tire pressure gauge: what it is for and how it works

Do you know what the tire pressure gauge is , what it is for and how to choose the right one for you? This is how the measuring tool that shows you the tire pressure works .

What is a tire pressure gauge used for?

Traveling with well inflated tires, neither too much nor too little, should be a goal of every conscientious motorist: how to do it?

You can often go to the tire shop (or service stations), or think about it yourself: at home, however, you will need a pressure gauge , a measuring instrument that allows you to check tire pressure.

This operation is essential for road safety and must be carried out periodically, especially before a long journey (read also: what checks to carry out before a long journey ).

Having a pressure gauge will therefore allow you to measure tire pressure easily, reliably and without spending too much. Here’s how they work.

How tire pressure gauges work

These are small pressure gauges , usually built in steel, which can be analog or digital (to be recharged), with dials in which to view the data detected in real time.

Where to buy? Both in auto parts stores and online. In any case, it is good to know that there are professional and economical models: the fundamental question is to check their measurement range before purchasing.

The economic models are certainly not as precise as those used by tire specialists, so you will have the difference of a few millibars: in this case our advice is to make a comparison, so as to know “how to measure” your new pressure gauge.

Remember that gauges do not inflate tires , but if they are equipped with the appropriate valve they can be used to deflate them.

Two tips: choose models with a long tube, so you can easily get to the tires, and those with a swivel head, so as to ensure comfortable measurements.

How to measure the pressure with the pressure gauge

How to measure tire pressure with the pressure gauge? This is quick and easy.

Remove the valve covers, read the correct tire pressure in the owner’s manual (or on the sticker in the door or on the fuel cover) and start measuring with the tool. Then close the lids and you are done!

Is it therefore convenient to have a pressure gauge, even of low quality? Usually yes, given the reduced costs and the numerous advantages, including economic ones, that you will obtain by carrying out the measurements independently.

Always remember that traveling with just a flat tire increases fuel consumption and wear, as well as decreases your road safety.
