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 PressureTire 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 pressureThe first cause is the loss of air pressure. Here are some of the reasons.
Wheel problemAlthough 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 damageDamageIn 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 changeMoreover, 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 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 problemIf 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 brokenValve is brokenSimilarly, 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.
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 From Losing Or Leaking AirTips To Keep Tires SafeTo 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 CheckFirst, 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 testWhen 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.
ConclusionMany 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.

I just picked up a 1991 Buick Regal for a good deal, but already the repair costs to get this thing up to speed are mounting :\
Right now I’m dealing with all four tires losing pressure.
The 24 year old car still has its original wheels (15 inch aluminum) and I’m assuming that they are losing pressure at the seal. The tires are only about a year old and the stems look okay, so do you think I’m on the right track?
There is one strange part to all of this: The vehicle with its equipped tires is rated at 30 PSI and if I fill them to 30 they are all down about five pounds within a few hours or after a drive. However, they do not lose more than or much more than 5 PSI. The front tires lose more air and lose it faster, but the lowest I’ve seen them is 23. Is only losing a few pounds of air and not going flat evidence of a seal leak or am I in the twilight zone?
Cheers.

It is very possible that those alloy wheels have become “porous” over the passage of over 2 decades.
Why not visit an auto recycler (junk yard), and buy a set of 4 steel wheels to mount the tires on? More than likely, this would resolve your problem at a relatively low cost.
If you don’t like the appearance of the “steelies”, you could buy some cheap wheel covers at Pep Boys.

I think VDCDriver is right. All 4 leaking is highly unusual. I suspect that someone used a solvent on the wheels and stripped off the clearcoat.
So if the tires are losing 5 psi in a few hours, you ought to be able to see that. Either spray the whole tire and wheel assembly with soapy water or dunk one. Look for bubbles. Patience is a virtue.

This is another vote for @VDCdriver since I went through this same problem a couple of years ago.
I had a tire shop seal the wheels internally which worked fairly well but they still leaked off a few pounds in a couple of months.

Also remove the valve caps and spray soapy water into the valves to check for leaks.

The only way I can see what you’re describing happening is that you drive home, find the tires at 25 psi, fill to 30, and and a few hours later (or next morning) they’re at 25 because they were warm when you filled them. Try filling all to 35 psi in the morning and see what happens.

I also vote for checking with soapy water.
With a leak that big, you’ll find it easily.

The local scrap yard has 15 inch steel wheels listed on their website at $34 (lugs included). This seems odd, as the local big tire store has new steel wheels for $39.99. So, I’m looking at about $50 plus installation for steels including wheel covers.
The big tire store also has new aftermarket aluminum wheels for $70 (salesman said he could probably knock a few bucks off if I bought them today, I assume I can still haggle for that). The aluminums aren’t gaudy and they would surely look better, but any performance or other reasons to opt for spending the additional $20 for the aluminum wheels?

On a 20+ year old car, I would suggest going with the cheapest possible solution, ergo a set of steelies.

The caveat is that this was a friend’s family car. It spent its first 15 years in Florida, garage parked. The last 8 it has been a mechanics “back up” car that he used in between car purchases and for long trips. It only has 113,000 miles with a GM 3800 v6 and everything aside from the r12 AC is in full original working order. I’m planning on getting another 100k out of this thing, though old transmissions have bit me in the behind before.

Do NOT get the aluminum aftermarket rims from the big tire store
They are undoubtedly Chinese, and are part of a limited production run
If you buy them and bend one going over a pothole a few months/years later .
. . the tire store will no longer carry them. And neither will anybody else. Then you once again will have a choice to make
Even if you buy the junkyard stamped steel rims, test fit one before buying. Even though the diameter is correct, the offset and width may not. You must make sure they don’t interfere with the brake calipers.

Before buying any new wheels I would have a tire shop bust the tires off the current rims, wire brush the beads on the rims, apply bead sealer and remount the tires. 9 out of 10 times alloy rims will stop leaking after this treatment.

I still recommend the first step being finding where the leaks are.
It might just be something simple.

Often, tire pressure decreases gradually, and this process continues for several days. You inflate them to the required level, but the tires again pass air over time. In this case, you should contact the tire shop, where they will determine the cause of the pressure loss. There may be several. We will look at the problems with tubeless tires, since most modern cars are equipped with them. nine0009

Disk damage usually leads to its deformation. This comes from hitting the wheel at high speed on the edge of the pit or on a steep and hard bump. Due to the loose fit of the tire to the rim, a partial air leak occurs. Keep in mind that damage may be hidden on the inside of the rim, while the outside of the wheel will look brand new, without any visual flaws.
Another possible reason for the gradual loss of pressure in the tires is the depressurization of the valve (or nipple) as a result of mechanical impact, or the ingress of the smallest dust particles into it.
If the mechanism is in good condition, then air can leak in the place where its valve is attached to the disk. Sometimes you can fix the problem by pumping the spool with a few sharp and short presses. nine0009
Quite often the tire “catches” a nail or other sharp and large object on the road, which safely gets stuck in the place of the puncture. In this case, it serves as a stopper, only not completely sealed, so the air will slowly but surely bleed. If a nail hits a tire with a camera, it instantly bursts, and at high speed this is fraught with an emergency.
A tire can be damaged not only on the tread side, where the thickest and most durable rubber layer is located. Its side is also vulnerable to contact with sharp objects. Usually in this place there are cuts from friction on curbs, the edge of the track, protruding rebar and other hard and sharp protrusions. How quickly the rubber will lose air depends on the depth of the scratch.
Usually damage to the sidewall causes irreparable damage to the tire, and it has to be replaced. nine0009
Whatever advanced rubber compound is used in the manufacture of a modern tire, in any case, its structure will respond to temperature changes to one degree or another. As a rule, in the cold, the rubber narrows, and as a result of a slight drop in pressure, the wheels sometimes have to be pumped up. Accordingly, at high temperatures, the opposite effect occurs and the pressure in the tires increases.

In the process of using the tire, a variety of damages can occur, most of which are to blame for the driver himself.
As a result, rubber is wasted, and since the law prohibits the use of different tire models on the same axle, you have to spend money on replacing the second tire.
The most common damage is puncture . This is the most harmless type of damage, but only if you notice it in time and repair it right away. It is absolutely impossible to drive on a flat tire, even a couple of meters! The damage caused by running on a flat tire or with low pressure is catastrophic. This causes the sidewalls to deform more than they should, which causes the tire to overheat, delaminate, and the carcass becomes unusable due to broken cords. As a result, the tire will have to be thrown away. In addition, the edge of the rim can also be damaged. nine0009
Punctures are of two types: with and without cord damage. To determine this, it is necessary to remove what pierced it. If the edges of the puncture tightly converge, then the cord is not damaged and it will be possible to repair the tire without removing it from the disk.
Otherwise, if the edges do not converge, you will have to disassemble the wheel and make repairs with strengthening the frame from the inside. Alternatively, in the field and in the absence of a spare wheel, such a puncture can be repaired without removing the tire from the rim, after which you can carefully drive to a tire fitting or garage and make a full repair. nine0009

When repairing, the puncture site should be cleaned and marked. Further, it all depends on what kind of repair kit you have - as a rule, instructions are attached to them. There are sealants that are poured into the tire through the nipple, after which the wheel turns with the puncture down and the substance seals the hole. Repair using a tourniquet or insert is somewhat more complicated, but also more durable: the edges of the hole are polished with a special tool, after which the tourniquet treated with a special compound must be inserted into the tire through a puncture with a special awl, pulled out (not completely) out and cut flush with the surface.

In case of cord damage due to a puncture, the tire must be removed from the rim in order to install a reinforced patch with additional cord on its inner surface. One of the sides of such patches has an adhesive layer that promotes cold vulcanization. After such a repair, wheel balancing will be required. To seal punctures from the inside, patches in the form of a mushroom are also used, with a leg that goes into the puncture. Such patches are also covered with a special adhesive for cold vulcanization. nine0009
Cuts or holes , unlike punctures, are not repairable, as they violate the integrity of the frame, which can no longer be strengthened. In addition, breakdowns are always sudden and occur on the go: the tire abruptly loses pressure and before the car comes to a complete stop it has time to make several revolutions “on the rims”, which breaks the cord and destroys the layers. It is not recommended to use such a weakened tire, even if it was possible to repair and strengthen the place of the rupture or cut, in the future.

Incorrect storage of tires can cause cracks . The danger of such damage is that moisture enters the cord through cracks, which renders the frame unusable. In addition, air can escape through cracks. Unfortunately, cracks are not repairable, and tires with them will not last long: sooner or later they will deform, become covered with swellings due to rusted and torn cord or because of driving with pressure below the recommended one. nine0009
Blisters or bulges can appear on a tire for a variety of reasons - it always happens due to a broken cord or delamination in the carcass. In the first case, an obstacle was hit and the impact broke the cord or the cord was cut through with a sharp object. In the second case, there is no damage on or near the hernia, which means that it appeared either due to a factory defect, or due to frequent driving with pressure below the recommended one.
The danger of hernias is that they can explode at any moment and provoke a skid, which will lead to an accident. If there is nothing to replace a tire with a hernia, then it is better to rearrange it to the rear axle and drive very carefully. Like cracks, a hernia cannot be repaired. Sometimes small blisters resulting from impacts or cuts are reinforced with reinforced patches, but there is no guarantee that the tire will not explode. Therefore, tires with hernias are recommended to be replaced immediately. nine0009

Tire sidewalls can be damaged by rubbing against curbs or the asphalt edge when pulling over. If you are prone to such a driving style, then it is recommended to inspect the inner and outer sidewalls from time to time and, if abrasion is found, swap the wheels in order to prevent the cord from being exposed - the rubber thickness on the sidewalls is small (1.
5–3 mm), and it can be rubbed to the frame very quickly. nine0009
Often the cause of tire damage can be poor-quality tire fitting , during which the bead ring was damaged. In this case, the tire loses its geometry and “sits” crookedly on the disk - it writes out “eights” during rotation, and lateral vibration appears during the ride. It is impossible to repair such a tire - you need to replace it with a serviceable one as soon as possible before it damages the suspension: rods, hubs and bearings.
You can find out whether you are using tires correctly and what invisible damage they have received by the characteristic wear of the tread, the varieties of which are collected in the table for convenience:
Double side shoulder wear
Driving with lower than recommended tire pressure.
Inflate the tires to the pressure recommended by the automaker (a plate with recommendations is attached in the driver's door opening) and find the cause of the fall: puncture, cracks, hernia, nipple, rust on the rim of the disc in the place where the tire fits, etc.
