How to Properly Check and Fill Tires – Tires must be inflated at a fair pressure to ensure their role, that is, to ensure the car’s handling, comfort, and limit fuel consumption. This operation is very simple and within reach of all, it is to be done every month.
1) How to know the inflation pressure of your tires?
The first thing to know is the exact pressure recommended for your tires.
This information is mentioned on a label stuck in the opening of the driver’s door or inside the gas door of your car.
It is also clearly indicated in your car’s onboard manual.
This pressure may be different between the front and rear tires, it is also variable depending on the load or the number of passengers.
In the bar, the pressure is usually between 1.8 and 3 bars at the manometer. A bar is equivalent to 1 kilogram per cm3.
The unit is different, but the result is the same: 2.2 kilos = 2.2 bars!
2) Locate the valve!
The valve is placed on the outside edge of the rim. Its access is sometimes difficult because of the hubcap.
Attention, the wheel of a car is dirty, especially because of the dust of the brake pads.
The valve is protected by a small plastic cap that screws and avoids pressure loss, do not stray this small plug and replace it systematically.
Most inflation stations put a plastic glove dispenser at the disposal of users, however, it is not uncommon for this one to be empty! Always have a pair of auto gloves in your vehicle.
3) Check the pressure
To check the pressure, place the inflator tip fully on the valve. Caution, there must be no air leakage and the inflator hose must be held on its own. If this is not the case, the inflator may be damaged, a defect that is quite recurring!
Adjust your pressure using the two buttons on the inflation terminal to inflate or deflate your tire. Once the pressure gauge is correct, quickly remove the nozzle from the inflator.
You learned during your apprenticeship for a driving license that you have to increase the pressure of 0.3 bars hot! If this assertion is true, it is always very difficult to know the temperature of a tire, especially with modern cars, depending on the outside temperature and the conditions of taxiing.
Therefore, always prefer to do a cold-pressure control, that is, after a journey of a small ten kilometers maximum.
Example: Cold pressure 2.5 bars/hot pressure 2.8 bars.
(5) Think of the spare wheel
The pressure of the spare wheel is generally neglected, it is true that the latter serves only every 150 000 kilometers according to the statistics, but in the case of a puncture having a spare tire deflated is useless! Check its pressure at least once a year. If your tires are worn, do not take any risks and order new ones, by selecting the brand and the models carefully. All tire manufacturers are found on 123pneus.
The indications of the inflators are not fair!
The pressure gauges of the inflation stations are not calibrated, and there is a large disparity between them. It is not uncommon to find from one inflator to another a difference of 0.4 bars. For this reason, it is preferable to use a personal manometer which allows for a greater precision, and above all to have always the same pressures from one verification to another.
With a pressure measurement always identical and comparable, you have the possibility to detect a possible leakage or loss of air on a tire, and thus a greater chance of detecting a slow puncture or a problem on the valve.
