Why Does My New Tire Keep Losing Air Pressure? 6 Reasons To Consider

New Tire Keep Losing Air Pressure

When pulling over to a petrol station, you notice one tire is flat. You drive away after filling it up with air. Unfortunately, the tires, again, are flattening, requiring extra air. 

You drive your car to an auto shop or a garage, but they are unable to inspect any problems. They could even soak the tire in water to check for punctures if there are any bubbles. Yet, nothing happens. Don’t worry, we will unveil the reasons behind it!

Why Does My New Tire Keep Losing Air Pressure?

Damage To The Tire Bead

tire bead damage

Tire bead damage might occur as a result of a weak sealing surface between your metal wheel and tire. This might be due to debris that has accumulated into the sealing gap between the wheel and tire, or the wheel corrosion is to blame for. 

When this happens, one apparent result is “bead chunking” – the bead of your tire tears or forms dimples or pin-sized holes. A broken seal is another obvious symptom of poor tire beading caused by weaker rubber and decreased flexibility.

The damage to the tires has already occurred in both situations. You’ll need new tires and, most likely, new wheels.

Changes In Temperature

Another reason could be temperature change. Furthermore, the change in weather renders the pressure of newly acquired tires to drop.

The air condenses when it’s chilly outside, and the pressure lowers more quickly. In order to keep your wheel at the proper level during the winter, you must check it on a regular basis.

What Tire Pressure Is Too Low - Quick Answer

Failure of the Valve Stem

Do you ever notice your tire valve stems until you’re filling up your tires or cleaning your car? Most likely not. 

Did you realize that tire valve stems may degrade with time? The plastic and rubber on your automobile tire’s valve will become more brittle as a result of road salts and other chemicals, resulting in gradual air leakage. (An overtightened tire stem core can also expedite the pace of degradation.)

Inadequate Seal

If you don’t properly seal the new tires, leaks are possible. Also, not cleaning the seal or properly removing the label makes the wheel not to fit together, which allows air in the new tire to escape.

A Gas Leak Has Occurred

Another reason why a tire keeps losing air is gas leaking. Gas leaks can sometimes cause brand new tires to lose their tension. Tire tension drops as a result of leaking gas, which can happen slowly or fast.

Punctured Tire Tread

Why does my tire keep losing air? The most obvious answer is there are holes on the tire!

Puncturing the tire tread and inner liner by crossing a sharp item like a nail can result in little to severe air loss on a regular basis. 

Although certain nails can stay in the tire for a short time without affecting the PSI, removing them is still the best choice since leaving them in might lead to tread separation and, eventually, a flat tire.

A tire patch or plug, together with a complete tire repair tool kit plus sealant, maybe the solution. However, a tire service professional is required to determine whether this is a viable choice.

How To Fix A Brand New Tire Losing Air Pressure?

Valve Stem Replacement

Valve Stem Replacement

A valve removal tool and a replacement valve core are necessary. If you find it simpler, you may also find a vehicle jack and a lug wrench to remove the wheel.

Insert the removal tool tip into the stem and rotate it counterclockwise to remove the valve core on the wheel where the tire loses air slowly. If the stem shows symptoms of rust, clean it before inserting a new core. Install a new core and inflate the tire.

Checking Regularly

To begin, the most basic thing you should do is check your car’s tire pressure regularly. The problem of leaks lowering PSI levels might occur slowly and quietly.

As a result, make it a practice to check your tires regularly to evaluate the level of leaks so that issues may be detected and fixed quickly. At the same time, you should inspect all of the wheels and avoid skipping any.


Above are some explanations of a brand new tire losing air pressure and how to fix them accurately. Hence, even if you recently bought your tires, you must always pay attention to evaluating the pressure of your tires to guarantee safe driving.
