Tires are one of the most critical components of the automotive system. So, every motorist should understand how to check the pressure in their tires. It promotes even tire wear, allowing them to last longer.

Why is Proper Tire Pressure Important?

Tire inflation testing may seem like a boring procedure. But don't let this discourage you. After all, this is one of the most essential aspects that you should consider to ensure road safety. So, let's look at why inflating automobile tires is so important:


First, tires are the only point of contact between the car and the road. This way, they play an important part in your security. Inflating car tires guarantees the vehicle's stability. It is necessary when driving on rainy or slick roads. Wheels with the proper pressure may minimize skidding and sudden loss of control.


No one likes to jolt along the road and feel every bump. Correct tire pressure helps ensure a smooth and comfortable ride. It amortizes shocks from road irregularities. So, when you put air in the tire, you create smooth driving. It helps to avoid vibrations and noise while moving.

Uniform load distribution

Adjusted tire pressure helps ensure the even load distribution on each tire. When the pressure is too low, some tread areas receive more stress than others. It can cause faster wear and disproportionate aging of the tires. Balanced pressure eliminates this problem, increasing the life of the tires.

So, correct tire pressure is not only crucial for safety. It is also important for your personal feelings. So, that's why you should put air in the tires.

When Should You Check Tire Pressure?

In auto mechanics, checking tire pressure is distinguished by its significance. But when exactly to put air in tires to reap its full benefits? Before diving deeper into the details, it is worth noting one thing. 

Studying tire inflation should be regular and not one-time. It is imperative because pressure can change. It happens due to various factors. These include temperature, wear, and other external conditions. So, what situations signal that it's time to examine the pressure? Keep a list:

After the change of the season

When you change tires due to the change of season, inflating car tires is necessary. Different types of them have other recommended pressure values. So, it is crucial to make sure that you adjust it according to the requirements of the appropriate season.

If you suspect some problems 

If you notice signs of unusual damage or handling problems, a tire pressure inspection can help identify possible causes. Insufficient or excessive inflation can lead to road hazards. So, it is worth checking tire pressure if you have any suspicions.

After a long trip

During a long journey, the tires can heat up, increasing their pressure. After the tires have cooled, the pressure may drop. So, measuring and controlling inflation to the acceptable amount is so critical.

2. Find the valves

Valves for inflating car tires are usually located on the sides of the tire rims. You can easily find them by carefully inspecting the outside of the tire:

  • They typically look like small metal or plastic protrusions.
  • When you look for the valve, you may notice a protective cap. It is a small cap that protects the valve from dust. 
  • If you spot it, you need to click on its valve to open access to it.
  • If you have trouble finding the valve visually, you can use your fingers to locate it. 
  • Just run your finger along the sides of the tire near the rim. 
  • Do this until you feel a small protrusion. 

3. Connect the manometer

Take this device in your hands. It is crucial to ensure it is properly set up to when to put air in tires. Its sensor should be ready for operation:

  • If everything is fine, gently push the tire inflator gauge head directly onto the tire valve.
  • Make sure the manometer fits tightly against the valve to avoid air leakage.
  • After connecting, wait until this instrument has a stable pressure value. 
  • And then, inspect the reading on the display or scale of the pressure gauge. It indicates the current inflation in the tire.

4. Measure the pressure

When the manometer shows you the indicators, ensure they have become stable:

  • If you need to measure the pressure in more than one tire, repeat this process for each tire separately. 
  • But remember that pressure can vary between front and rear tires. 
  • Thus, checking tire pressure in all tires is worthwhile.

5. Adjust the pressure

If the pressure indicators in various tires differ, it is important to change them. Adjusting the pressure is a simple and effective procedure. It can improve the ride quality and ensure longer tire life. How to do it?

  • Add air if the pressure readings are lower than indicated. 
  • Connect a compressor to the wheel valve to do this. 
  • Inflating car tires until the required pressure is obtained. If the measured pressure levels are higher than recommended, it is necessary to remove air.
