Car tyre pressure – 8 reasons why is it extremely important?

Car tyre pressure is the amount of air in your car’s tyre. It is not only crucial for safety purposes but also important for increasing the tyre’s life. Sad to say, but many car owners indeed ignore it. Most people check it only when the tyre looks saggy due to low air. Even that also sometimes a pedestrian or another rider points it out! 

Tyres are the only part of the car that connects it with the ground. So, the connection should be solid and stable; otherwise, it can lead to a mishap. Hence, one should not only keep the pressure in check but also maintain it at regular intervals. 

In this article, I am going to discuss why car tyre pressure is essential. I will also tell you some tips to make it a habit also, how you can self-check it at home, and the right amount of pressure for your car’s tyre.

Why is it important?

Every component in the car should be checked and well-maintained. Even the most minor element can cause trouble on the road. Tyres are a very crucial part of the mechanism of the vehicle. Proper tyre pressure, balanced wheels, and aligned suspension go hand in hand. All three are interdependent. Even if one is faulty, it affects the other two factors. It can cause a problem for the driver, passengers, and the vehicle itself.

I have mentioned 8 reasons why proper pressure in the tyre is essential:

  1. Under-inflated tyres get easily damaged structurally. The sidewalls of the tyre can get damaged, making the vehicle less stable. 
  2.  Underinflated tyres are more prone to punctures, bulging, and cuts.
  3.  If one of the tyres is not running on proper pressure, it may cause strain on the suspension. It can lead to wheel alignment issues. Hence, it will not only cause wear and tear but also handling issues.
  4.  Improper tyre pressure may damage the rims when driven over bad roads, especially at high speeds.
  5.  With low air pressure, the tyre can burst due to heat and pressure build-up. At high speeds, it can be hazardous.
  6.  If the air pressure in the tyres is uneven, cornering at high speeds could be troublesome. You may feel the tyre wobble and give out under the vehicle.
  7.  Steering becomes unresponsive and feels heavier when the air pressure is not proper in the tyre.
  8.  Underinflated tyres increase friction between the tyres and the road surface. Therefore reducing the fuel efficiency of the vehicle. As a result, it can reduce the tyre life, and you may have to replace the tyres early.

How to check the pressure of air in the tyre?

You should self-check your car tyre pressure. Getting it checked at a petrol station is undoubtedly convenient, but it is advisable that you self-check it.

The easiest way to self-check your car tyre pressure is by a visual look at it. If you are a regular vehicle user, i.e., your daily commute on your vehicle, you should make self-checking the pressure of the tyre a habit. You can experience a humming sound in your car if the car tyre pressure is too low, especially at high speeds.

Before coming to how to inflate the tyre let us know when is the appropriate time to check the car tyre pressure. 

Test the pressure with cold tyres.

What it means is one should measure the air pressure of a tyre before a cold starts. In other words, the correct pressure is measured before first starting the car every day. It should not be estimated after running the car for a few kilometers. It is because the air inside the tyre heats up and expands, hence not giving an appropriate reading.

That is why car experts suggest not only to self-check the air pressure in the tyre but also to self-inflate it.

Using a tyre pressure gauge and inflator.

The best and easiest way to measure the pressure in the tyre is by using a tyre pressure gauge. Know your car’s recommended tyre pressure, which is usually mentioned in the user manual of the vehicle. Use the air pressure gauge to know the exact amount of air in your car’s tyres. 

You can buy an air pressure gauge easily online. Usually, there are three types of air pressure gauges – stick type, dial type, and digital. 

The next step is to use an inflator to fill in the air. There are many air inflators available in local shops and online. Also, remember to recheck the car tyre pressure after filling the air. Keep repeating the process of checking and refilling till you reach your recommended reading.

In-built air pressure monitoring system.

Modern cars nowadays come with an in-built tyre pressure monitoring system. Usually, this feature is in the top-spec variant of the vehicle. This feature lets you know the tyre pressure in your car. It warns you if the car tyre pressure is low. The critical point is to act upon it timely. Go to the nearest shop to inflate it or self-inflate it using an inflator.

Checking car tyre pressure without a gauge.

If you have neither an air pressure gauge nor an in-built air pressure monitoring system, here are some ways to check the pressure.

  1. You can feel the tyre by putting some force using your hand or foot. If the tyre remains firm, then the car tyre pressure is normal. If the surface of the tyre gives in, then it is underinflated.
  2.  Sometimes, when the tyre pressure is too low, you can tell by looking at it. It will look saggy.
  3.  If your car feels bumpier than usual, unstable at turns, or the steering feels heavier than usual, it may be underinflated.
  4.  Increase in NVH levels. NVH stands for noise, vibrations, and harshness. If these things increase inside the cabin of your car, even with windows closed, the tyres may be underinflated.

The correct tyre pressure for a car.

You can find the correct tyre pressure for your car in the user manual, which you get with the vehicle for hatch-backs and midsize sedans, which are very common in India. The ideal tyre pressure is 32-35 PSI/cold. By cold, as mentioned earlier, we mean the tyres did not roll for at least 2-3 hours.

How can you maintain your car tyre pressure? 

We have some tips for you which can help you maintain the correct car tyre pressure.

  1. Buy an air pressure gauge so that measuring your car tyre pressure is quite handy. 
  2.  Buy an inflator that is not too expensive. It will not only help you in keeping check of your car tyre pressure but also on long journeys it will be of great help. You can even buy a manual air pump if you don’t mind the hassle for some time.
  3.  Or the easiest way to get your tyre pressure in check is to go to a petrol station and get it done for free. According to Indian motor laws, all petrol stations must have free-to-use air filling stations. So, if you want to avoid doing it yourself, getting it done at the nearest petrol station is the easiest option.
