Your tires are where the rubber meets the road – literally – when it comes to the safety and performance of your car. That means, if your tire is leaky, you could be putting your safety at risk.
A leaky tire causes low tire pressure, which can decrease fuel economy, and put you at risk for a blowout. It also decreases the ability of your car to handle properly, making it more difficult to respond to emergency situations or drive in inclement weather.
In this article, we’ll discuss how you can diagnose and fix slow tire leaks. Don’t just ignore that low pressure sensor – check out this guide!
The Most Common Causes Of Slow Tire LeaksThere are three common issues that cause slow tire leaks. Let’s discuss each one of them now.
If your valve stem is damaged, there will be a slow and constant leak. This leak could come from either the body of the valve, or the base of the valve, where it meets the tire.
Contrary to popular belief, puncture damage usually doesn’t lead to an immediate flat tire or blowout, in most cases. This is because the object usually remains lodged in the rubber, preventing air from leaking quickly.
There are a few ways you can diagnose a slow tire leak
If one of your tires seems perpetually under inflated, chances are you have a leak.If you have a slow tire leak, you’ll want to have it repaired professionally as soon as possible. In some cases, you may want to keep a tire plug or patch kit in your vehicle. These kits are easy to use, and can keep your tire inflated until you bring it to a professional tire repair shop.
To permanently fix a tire leak caused by a puncture, you will need a “plug and patch”. This method of repair involves removing the tire from the wheel, and placing a combination plug and patch on the tire.
If your leak is caused by a faulty valve, you may need to replace it or your tire.
Leaks caused by a damaged mounting surface may require you to replace the entire wheel.

A slow tire leak is more than just a nuisance. A leak can lead to low tire pressure. Not to mention, prolonged running on an underinflated tire can lead to more extensive tire damage or even cause a dangerous blowout.
If you’re experiencing a slow leak, here are some things to look for:A tire puncture: It is a common misconception that a puncture will cause the tire to immediately go flat. However, in many cases the object that caused the puncture remains lodged in the tire and prevents the air from leaking out quickly.
As with all tire leaks, it is important not to ignore a puncture. Eventually the object will either wear down and/or work its way out of the tire. For more on this read our article How to Repair a Tire with a Safe, Permanent Fix.
Wheel damage: Another common cause for slow tire leaks is damage to the area where the tire bead meets the rim. This type of damage is typically cause by the driver hitting the curb, taking a speed bump at high speeds OR those dreaded potholes! The impact deforms the wheel’s metal surface which may cause the tire to pull away from the mounting surface of the wheel.
Valve stem damage: The third most common cause for slow tire leaks is worn out or damaged valve stems. Time, use and exposure to elements can cause your valve stems to wear out and cause leaks.
Diagnosing your tire leak:
If your vehicle is equipped with TPMS, you will know right away if you have a leak. If the sensor light on your dashboard goes off, you inflate all the tires back to proper pressure and the light goes back on a few days later – you likely have a leak.
If your vehicle does not have TPMS, its important to check your tire pressure regularly.
Once you’ve identified that you have a leak, use TECH Chek to locate the source of your leak. Simply spray the product all around the tire. Where the surface of the tire begins to bubble is likely the source of your leak.
It’s important to have your tire diagnosed by a professionally trained tire shop or mobile tire repair service as soon as possible. In the case of a puncture, you may want to use a tire repair kit to keep your tire properly inflated until you can have it serviced. The leak should then be permanently fixed using a proper tire repair consisting of a cured rubber stem and repair unit.
If the leak is caused by a damaged valve, a trained tire technician can typically replace the valve at a minimal cost. In some cases, however, the tire may need replaced.
If the leak is caused by a damaged wheel, a tire technician may be able to reseat and seal the tire using a bead sealer.
However, if the damage to the wheel is significant, unfortunately that means you may need to replace the wheel itself.

Most often, we ourselves are to blame for the fact that tires become unusable. But this can be avoided.

You have never seen such tires: even the police were surprised
In the process of using a tire, a variety of damages can occur, most of which are the fault of the driver. 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.
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.

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 damage to the cord due to a puncture, the tire must be removed from the rim in order to install a reinforced patch with an 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.
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.

8 tire storage rules - do you follow them all?
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.
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.

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.
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 disc rim in the place where the tire fits, etc.
Center wear
Tire pressure too high.
Reduce the pressure to the recommended (indicated on the tablet in the driver's doorway)
In the form of rings and furrows
can be found on trailers or rear wheels of pickups and vans due to vibrations and vibrations and vibrations due to vibrations and vibrations bouncing at high speeds.
Changing wheels on a loaded axle to equalize wear, driving with a heavier load.
Chipped wear with cuts
Frequent wheel spin on rocky surfaces.
Move the wheels to a non-driving axle, use the gas pedal more carefully when starting to move.

It is not uncommon for tire pressure to drop gradually over 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.

Damage to the disc usually results in deformation of the disc. 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 cause of a gradual loss of pressure in the tires is the depressurization of the spool (or nipple) as a result of mechanical impact, or the ingress of tiny 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.
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.
