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.

So, you have a flat tire or one that’s leaking air.
It’s not the end of the world. Luckily there are safe and cost-effective ways to properly repair most tire punctures. The purpose of this article is to show you the difference between a safe, permanent repair and a temporary string, plug or patch repair.
According to the National Highway Traffic Safety Administration (NHSTA) and the Tire Industry Association (TIA), the only method to properly repair a tire puncture is to fill the injury with a repair stem and back the stem with a repair patch. This is commonly known as a combination repair or a patch/plug repair.
Patch/plug repairs are most often performed using a one-piece repair unit that combines the repair stem and cap (or patch) into one unit. However, special circumstances may require the use of a two-piece combination repair (ex. If the angle of the puncture exceeds 35 degrees). The repair is then permanently bonded to the inside of tire and through the injury channel using a cold, chemical vulcanizing process. The repair essentially becomes part of the tire, creating an air-tight seal that keeps air in and moisture and contaminants out (more on this procedure below).
Emergency roadside plug repairs are NOT intended to be a permanent tire repair. Plugs and string repairs are designed to get you back up and rolling long enough to get home or to the nearest service center to perform a proper tire repair.
The common misconception with plug and string repairs is that because they hold air, they are safe to use. While it is true that many plug repairs do a great job of keeping air in the tire, that’s only part of the equation. Because they’re not completely sealing the injury, plug repairs may allow air and moisture to penetrate the body of the tire. Over time, this could lead to a dangerous (or even deadly) blowout.
A Patch-Only Tire Repair Leaves Your Tire Susceptible to DamageA tire repair that uses only a patch is also NOT considered proper or safe. A properly installed patch will do a great job of allowing the tire to hold air. However, similarly to the plug-only repair, the patch does not fill the injury channel.
Therefore, air and moisture could seep into the tire from the tread surface and eventually damage the tire.
Only a proper patch/plug repair completely seals the puncture from inside the tire and through the entire injury channel. There are a few extra steps necessary to perform a proper tire repair in accordance with industry guidelines. We’ve developed a simple acronym to help organize and remember the steps: R.E.P.A.I.R.
First, the injury is drilled out using a carbide cutter to strip away and damaged cords or belts. Next, the inner liner is cleaned and buffed to a slightly rough texture. This also helps maximize adhesion of the patch/plug repair.There are a number of factors that may determine whether or not your tire is safe to repair.
These factors fall into three main categories:
The occasional flat or leaky tire is an unavoidable part of life. But, taking shortcuts to repair it can be dangerous to you and your passengers.
Take the time and do the research to do the job right and/or find a reputable tire repair shop trained in proper tire repair procedure.
On the road, various troubles can happen to a car and a rubber puncture on a car is a common case.
The absence of a spare wheel or a standard "roll-in" seriously complicates the situation. If the driver has the skills, you can put a temporary patch on the puncture, otherwise you will have to order a tow truck.
We recommend carrying a spare wheel, a repair kit for various occasions, the necessary tools, then you can get out of any traffic situation with dignity. If all this is not there, then you can drive on punched rubber a short distance to a service station or tire fitting. We are not talking about hundreds of kilometers of travel, we are talking about a short distance. nine0003
Leakage of air from a car tire can occur in different situations.
At the same time, punching is not necessary, there are other unforeseen and unpleasant situations. Most common:
Potholes or bumps in the road can be a serious problem. Hitting such an obstacle at high speed can lead to deformation of the car disk, subsequently to damage to the rubber. Very serious damage, which is impossible to fix on your own, without the use of special equipment, you need to go to a tire service.
Use of used car tires - adhere to manufacturer's specified service life. Otherwise, the wheel may deflate due to high wear. There is a risk of explosion directly during operation. nine0003
Problems exist with tubeless tires - the fitting sometimes does not fit well on the disc, air leaks.
The main causes that lead to damage to car tires and air leakage are indicated. Whether it is possible to drive on a flat tire is determined by the driver himself, taking into account his experience and capabilities.
Driving with a flat tire is not recommended. Driving a car is significantly more difficult, there is a risk of getting into an accident, creating a threat to other road users. nine0003
Among the main problems that can lead to driving with low tire pressure are:
A flat tire is a serious hazard. Each driver must understand this and take all necessary measures to eliminate the problem. In no case should a puncture be ignored, at high speed the situation can completely get out of control. The ideal would be to replace the wheel with a spare, repair at the nearest tire shop. nine0003
A car tire is a complex system. Consists of different elements. Manufacturers use special technologies and materials to provide the declared driving characteristics of the car. The special pattern on the main part of the tire has its own functionality, and does not serve solely for beauty. Any deviation from the norm leads to a decrease in the functionality of the tire, respectively, the car loses its qualities. Its use becomes unsafe until the problem is solved.

It is worth noting that under no circumstances should you drive with a completely flat tire.
The situation can get out of control of the driver at any time, the tire will fly off the disk, he will receive damage that will lead to new problems. It's best to call a tow truck, no matter the cost. nine0003
An exception to the rule may be a tire that still has some air left in it. You can try to get to a service station or tire fitting. You can also try to inflate the tire to give yourself more time.
Low pressure driving is possible subject to the following rules:
The average distance allowed to drive with a half-flat tire is 10 kilometers. This is only allowed if the above rules are observed.
Delays in dealing with low tire pressure, punctures or other damage will result in negative consequences.
The following systems may experience problems:
A car with flat tires is a danger to other road users and its driving characteristics are affected.
It must be understood that movement with insufficient pressure leads to deformation of the rubber. You run the risk of completely damaging the tire, subsequently replacing it with a new one. Therefore, the decision to drive on half-flat tires must be made carefully, carefully evaluate all the consequences and alternatives. For example, estimate the cost of replacing, repairing other damage with the price of a tow truck or calling a mobile tire fitting team. nine0003
The maximum speed on a car with a half-flat tire depends solely on the characteristics of the tires, the type of vehicle, and other nuances. When accelerating to a speed of more than 30 km / h, complete disassembly is possible, the tire flies off the disk.
We recommend that you have a spare wheel with you, which is supplied with the car by the manufacturer, a repair kit. You will be able to revive the wheel for a while, it will not deflate and it will be possible to get to the tire fitting. nine0003

Most vehicles are fitted with tubeless wheels that maintain tire pressure during a puncture.
They guarantee safe driving even when flat, and with little damage they can hold their shape for several days. Despite their practicality, you should immediately look for the causes of wheel leaks.
If you do not repair a punctured car tire in advance or do not fix warped alloy wheels, the operation of the car will lead to an emergency. nine0003
Since even tubeless tires flat for no apparent reason, you need to carefully inspect the car and the condition of the disks in order to detect a malfunction in advance. This will help to avoid a number of problems during the trip. Driving with flat tires adversely affects the performance of the machine. The vehicle has poor traction, the steering wheel pulls to the side with a bad tire, acceleration and braking are deteriorating. If the tires of the car are slowly deflated, this leads to increased fuel consumption. nine0003
To understand the problem, let's examine the reasons for which it releases air:
It can bleed due to stones found on unpaved surfaces. More often, a metal object gets stuck in the wheel tread without damaging the rim and alloy wheel. Since the screw or nail remains in the tread, the air escapes slowly, which allows you to safely drive to the service. Pulling out the item yourself, if it is not possible to immediately fix the wheel, is not worth it. This will lead to depressurization. nine0016 
Due to the leaky fit, air slowly escapes into the gap formed. In addition to depressurization, such a breakdown can cause a “hernia”, the appearance of a beating steering wheel or vibration of the car body. The problem is fixed in the profile service by aligning the rim of the alloy wheel. nine0016 It is often difficult to find the reason why the air in the wheel slowly bleeds. Even the masters can not always immediately detect a malfunction. You can find the problem yourself in the following way - pump over 1-2 atmosphere and listen to see if air comes out.
If no sound is heard, then the wheel is wetted in a soapy solution and lowered into water. The area where air will begin to bubble will be the puncture site. nine0003
In cases where the wheel bleeds air on the car, but does not deflate when it is removed, it is necessary to disassemble and wipe the inside of the tire. In the presence of sharp objects, the fabric will catch on, indicating the puncture site.
Find the causes of rubber puncture near the nipple, on the rim of the alloy wheel or in the tread using indirect causes: ; nine0016
If the tire on the car began to slowly deflate as a result of a side cut, then such repairs are not easy to make even for masters.
Unlike a tread puncture, the area near the rim of an alloy wheel is softer and thinner. This does not allow you to put a patch or install a harness. Even after removing the cause, the damaged wheel will slowly bleed under load. Also, repairing a side puncture is dangerous because it affects the durability of the tire. Therefore, with a strong side cut, it is better to change the wheel to a new one. nine0003
In the event that a tread puncture is the cause of air bleeding, the tire can be easily repaired. It is important that in this case the rim of the cast disk is not damaged, and the hole size is no more than 4-5 mm. If a larger object hits, it will not be possible to repair the wheel on your own, so you need to sign up for a service station. If the tire on the car descends slowly, and the puncture diameter is several millimeters, a rubber band, glue and an awl will be needed for repair.
If the tire bead does not seal against the rim, the defect in the cast rim must be repaired first.
There are many reasons why a dent appeared on the surface - due to falling into a hole at speed, upon contact with the curb. If you do not align the disk, the tire will slowly deflate, it may depressurize when driving a car. Dents are "rolled" in the service. You can fix the breakdown on your own on the road with the help of a heavy object - sometimes it is enough to hit the rim with a hammer to stop lowering. However, this is a temporary option. nine0003
If the rim is OK and the wheel continues to bleed, the problem may be in the spool. On the road, such a “puncture” can be corrected by pressing hard on the nipple. In case of deformation of the nipple, contact the specialists, as it needs to be changed.
Since the wheel itself may be the reason why the wheel began to deflate, let's look at the problem in more detail. The rim is damaged when hitting a curb, due to old age or improper storage, which affects the tightness of its fit to the tire.
Deformation of a cast wheel is also possible due to poor-quality alloy. nine0003
In case of advanced corrosion or mechanical damage to the rim, the disc is repaired or replaced with a new one. It is forbidden to pour sealant inside. It won't fix the rim problem, but it will definitely ruin the tire.
