Brand New Tire Losing Air Pressure: Causes & Fix

Tire pressure has a significant influence on vehicle performance, durability and fuel economy. However, most people face the problem of air leaks that reduce wheel pressure.

One of the issues that people are very concerned about is brand new tire losing air pressure. Normally, the degree of escape is related to tire life. With new tires, it is quite rare unless it is experiencing some external impact.

Let’s explore the following article to understand better the causes and how to fix the pressure drop in new tires.

Why Is Tire Pressure Important?

Tire pressure is understood as the pressure of air compressed inside the tire. This one dramatically affects the operating characteristics of the new tire.

More specifically, inflating the new tires at the correct pressure helps the wheelchair roll on the road with the full tread. The contact surface is spread evenly, thereby helping to wear the surface evenly.

Besides, a set of properly inflated new tires also brings direct benefits to the user, such as optimal smoothness, stable cornering ability, shortest braking distance, and fuel economy.

Pressure is significant to the use of your car because it directly affects the performance, durability, and optimal function of the brakes and suspension systems equipped on the vehicle.

At the same time, maintaining the correct pressure helps you maintain safety, vehicle load, wheel life, and fuel consumption.

Therefore, you need to check your new tires regularly to ensure the pressure is always at the most stable level.

Why Does Your Brand New Tire Lose Air Pressure And Leak Air?

Next, to better understand the condition of new tires leaking air, let’s learn about some of the causes of this condition.

Loss of air pressure

The first cause is the loss of air pressure. Here are some of the reasons.

Wheel problem

Although very careful, when you just change a new tire, the risk of wheel failure can occur. The common problem is that your tire valve stem is of poor quality.

When changing a new tire, it is better to replace the valve with a new one. Also, don’t forget to check it regularly to determine if it’s working correctly. Besides, if the valve core is too tight, it can also cause air to leak.

Another problem is that damaged, warped, deformed wheels due to impact also cause pressure to drop.

Tire damage


In addition to the wheels, problems related to tires include rolling a nail or sharp object that punctures the new tire damaged, broken, and reduces the pressure quickly.

When moving on the road, you need to pay attention to the terrain. You accidentally go into potholes at high speed; it can also cause new tires to leak air.

Temperature change

Moreover, the change in weather is also the reason why the pressure of newly purchased tires decreases.

When it’s cold, the air contracts, and the pressure level drops faster. So, you need to regularly check your wheel in the winter to maintain it at the right level.

Gas leak

Gas leaks can also be the cause of brand new tires losing tension. Leaking gas causes a drop in tire tension, and this can happen slowly or very quickly.

Assembly problem

If there is a problem during the assembly process that causes the rims and tires not to fit properly, it will also cause air to leak faster.

Valve is broken

Similarly, if you buy a new car but use an old valve or a new valve that comes with a damaged tire, it will also cause air to escape.

Usually, this speed is relatively slow. Therefore, it will be difficult to detect now but check the valve regularly to limit this situation.

Temperature change – Variation

The temperature change will also cause the air in the wheel to escape. The molecules are often more concentrated when it is cold, shrinking, reducing tension. Statistically, every 10°F drop in temperature reduces stress by about one psi.

Improper seal

Finally, if you don’t seal the new tires properly, it can easily lead to leaks. Besides, not cleaning the seal not or adequately removing the label also causes the wheel not to fit together, and this creates a space for air in the new tire to escape.

Tips To Keep Tires Safe

To ensure safety during travel, it is essential to keep the tension stable. Some tips to help you maintain it at an appropriate level and limit losing or leaking:

Regular Check

First, the simple thing that you need to pay attention to is regularly checking your car’s tension. The problem of leaks reducing stress can happen slowly and silently.

Therefore, try to maintain the habit of checking your tires weekly to determine the extent of tension leaks to detect and fix problems in time. At the same time, you need to check all the wheels and should not skip any.

Cold test

When temperature drops, the air in the wheel can also contract, reducing the tension. Therefore, in the cold season, you need to check the tension with a higher frequency.

To determine the tension level accurately, you need to park the car in the shade and stop starting the engine at least 15 minutes before. Otherwise, the displayed tension level is incorrect and should remove about 2psi of inflation.

Use a standard tension gauge.

Finally, it would help if you used a standard tension gauge to determine the exact tension level of the tire. Yet, you should also note that some meters may display a tension difference of about +/- 3psi depending on the vehicle type.

Therefore, a quality tool is an indispensable tool to help you determine this correct tension level.


Many reasons lead to the situation of brand new tires losing tension. Therefore, you always need to pay attention to the issue of checking the stress of your tires, even you just bought them to ensure safe driving.

With the information we have provided, you can clearly understand the importance of car tension and how to fix the brand new tire leaking air.
