How to check tire pressure

Traveling in a car with flat tires will make you consume more , go slower and be less safe: for this reason, a fundamental habit to learn to internalize is precisely the control of tire pressure, to be carried out constantly.

The habit of checking tires

Checking tire pressure is a very important DIY maintenance habit, although most drivers forget about it (or put it off for too long).

The operation is actually very fast, it is part of the checks that can be carried out in total autonomy and to carry it out you do not need particular technical skills: in fact, you just need the right tools.

Here are the basic steps to travel with the right tire pressure and how (and when) to check.

How to check tires

Pressure control with the pressure gauge

Meanwhile, check your tire pressure at least once a month ; furthermore, a check before a longer trip is essential .

To do this, you will need a pressure gauge , possibly of good quality and well calibrated: you can buy one, or go to a service station, but you need to know how to read the data. Alternatively, you will necessarily have to go to a workshop or to the tire shop.

Remember to measure the pressure only with cold tires and with the vehicle parked on a level surface : obviously, if you first had to go to the petrol station for the check, look for one within 2 km of distance. Otherwise, the tires will get too hot due to rolling, distorting the reading (higher than reality).

The recommended pressures for the car under test are shown in the maintenance booklet or on the adhesive plate placed in the driver’s door, and are expressed in bars. the heavier it is, the higher the recommended tire pressure.

Tire inflation: details to remember

Always check the tire pressure : if it is low, to restore it and therefore inflate the tire you must unscrew the valve cap to be able to introduce air, progressively, up to the recommended level.

Always respect any differences between the front and rear axles imposed by the manufacturer, and also check the spare wheel: it does not remain closed in its housing ready for use for years, but can deflate or deteriorate.

If you only have the inflation kit, you must still periodically check that it is working: to do this, turn it on by connecting it to the cigarette lighter of the car, and then put it away carefully.

At this point, remember that there are many cars equipped with electronic tire pressure control systems : on those with sensors on each wheel after each inflation you will have to reset the on-board computer (the instructions are always in the owner’s manual. and maintenance).
