As tires naturally lose some air, it is important to check your tire pressure regularly. Without this, you risk losing grip and increasing your braking distances. You can also damage your tires, shorten their life and increase your fuel consumption.
Let's see how to avoid these risks.
How to check the tire pressure of your car?
In a petrol station and at a Dealer
The easiest way to do this is to go to a petrol station that has an inflation zone.
After identifying the pressure recommended by the manufacturer, insert the compressor nozzle onto the valve.
Check whether the tire pressure indicated corresponds to the recommendation.
If not, press the button to inflate until the correct pressure is reached.
With a portable compressor
You can also check and adjust your tire pressure from home. All you need is a portable compressor, which you can buy in stores.
Car accessories such as MICHELIN portable compressor are available on Michelin Lifestyle Ltd as well as a vast array of branded products.
It is best to use the same compressor for each check so that a difference in calibration between the two devices does not affect the pressure level of your tires.
When should you check tire pressure?
Always check your tire pressure when the tires have not been driven or have been driven very little.
Why? Because when you drive, the tires heat up, which causes their pressure to rise. If you check your tire pressure after driving for a long time, you will feel that your tires are over-inflated and you may be tempted (wrongly) to remove air in order to adjust.
It is recommended that you check your tire pressure when the vehicle has been driven less than 2 km. This will give you a true picture of your tire pressure. If necessary, you can adjust by adding air if the pressure is low.
What about the spare wheel?
The spare tire is often overlooked in the tire pressure checking process. However, if your vehicle is equipped with one, you should be able to rely on it if one of your tires goes flat. The spare tire also needs to be checked regularly, even if it is not used daily. So remember to check its pressure too.
How often should you check tire pressure?
There is a small amount of normal air loss regardless of the age of your tires and their level of wear. As the tire rolls, it loses some air. Therefore, to avoid the risks mentioned above, we recommend that you check your tire pressure once a month.
Causes of pressure loss
Why do some tires deflate faster than others?
There are various reasons:
- If the valve of the tire is a little porous, the tire loses air faster than normal.
- When the rim is old and rusty, this can also cause damage to the tire and lead to a loss of pressure.
- If your vehicle is always parked in the same place, tires exposed to the sun lose air faster than those that are not.
- A puncture, for example caused by a nail, can result in a slow and steady loss of pressure.
During your monthly check, if you notice a significant difference in pressure between one tire and the others, it could be a fault. In this case, have it checked by a professional.
Otherwise, small differences in tire pressure from one tire to another are common. Just get into the habit of checking the tire pressure every month to avoid under-inflation and premature wear of your tires.
