As a car owner, you need properly working tires for a seamless driving experience; however, your tires could still develop problems despite the introduction of the more advanced tubeless tires.
Tire leakage is one of the most common issues for most drivers because it happens unexpectedly. If your tire has a leak around the rim, how do you fix it? Here’s all you need to know!
Tires leak air around the rim because of punctures, tire bead damage, ripped tires, rim problems, or deteriorating valve systems. To fix the leak, drivers have to remove the tire to reseat the bead and reseal, which can be done at home if you have the appropriate equipment or with the help of a mechanic if the inner-tube tires need fixing.
For more information about what causes the tire to leak around the rim, how to fix and prevent it, and how much it will cost to repair your tires, read on!
Identifying a rim tire leak can be difficult to notice at first if your car has a slow leak; however, if your vehicle has a built-in tire-pressure monitor system or TPMS, you’ll get a low-pressure notification because the leak causes the PSI )pounds per square inch) to decrease.
If your tire is leaking, here are the reasons why this could be happening.
Tire Puncture
Once you run over a sharp object, you could puncture your tire. While most drivers assume that the puncture will cause the tire to go flat immediately, this is not usually the case, and the hole might cause a slow two-to-three PSI leak per week.
In some cases, the sharp object like a nail can remain lodged in the tire, which prevents the air from leaking out quickly.
Whether it’s a minor damage or not, you shouldn’t ignore the leak as this may lead to extensive tears and tire damage.
According to The Inflator, approximately seven tire punctures occur every second in the U.S. alone; therefore, this is the first thing you should check for when there’s a leak.
Valve Stem Damage
Valve stems are critical parts of the tire system, and they come in different forms and sizes depending on the tire.
These stems are the tiny protrusions on your tire that you unscrew during inflation; therefore, they need to be in good shape, without any damages or dirt-clogged.
Additionally, when valve stems get exposed to elements over time, they become worn out or corroded, which can cause the air to leak around the rim.
Bead Leak
Tire leaks can also result from bead damage, where the tire seals itself to the rim.
To know whether the bead is the problem, you’ll need to determine how old the tire is because if your tire has dry rot or is older, it may no longer seal properly and have reduced elasticity.
Additionally, beads also get damaged because of a corroded rim or when the tire is mounted or removed using a tire lube.
Your entire wheel gets this type of damage if you regularly hit potholes or bumps at high speed, deforming the wheel’s metal surface, which may cause the tire to pull away.
Keep in mind that if the bead is damaged and you can’t seal the tire to the rim, you have to replace the tire.
Rim Issues
If you are using aluminum or magnesium alloy wheels, your wheels are more susceptible to corrosion, which affects the part where the rim meets the tire bead.
Rim damage can be caused by several causes, especially if you are constantly driving on bad roads with many potholes.
Before installing new tires, ensure your technician checks the bead seal and wheel correctly to confirm that the rims are not corroded.
Furthermore, check for wheel porosity that causes air to leak from the rim due to corrosion, incorrect wheel weights, or poor casting. To fix the leaking issue, avoid injecting a tire sealant and fix the rim first.
Once you discover that your tire is leaking air around the rim, what next? Here are some steps to guide you.
1. Remove The Tire
To identify the cause of the leak, you’ll need to remove the tire and place it on a flat surface with the valve stems facing up.
2. Fill The Tire And Rim With Soapy Water
Add soapy water to your tire; around the outer edge of the rim, the area of the leak will be identifiable through bubbles from the leaking air.
Mark the area and move to the next step.
3. Release Air From The Valve Stem
After you’ve marked the area, empty the air from your tire by pressing inward on the valve system using the valve removing kit in your car or unscrewing it from the stem.
4. Separate The Tire and Rim
Since the tire and the rim are attached with a seal, you’ll need something heavy like a wood board to separate them.
Use a hammer to hit the wooden plank until the tire’s bead breaks free from the rim.
5. Clean The Tire and Repair
Once the two parts separate, you can stop the leak around the rim by cleaning the tire’s edges with a cloth to remove loose debris and dirt.
After the cleaning is done, you can add some repairing solution to the leakage and start filling the air.
Once you fill the tire with the desired air pressure, you can check again for any leakages using the same process with soapy water.
Fixing a tire rim leak can be expensive or affordable, depending on the leak’s cause and where you get the service done.
According to customer reviews, if you get the leak repaired at the shop you bought the tire from, you are more likely to get this service for free, but if you go to a different dealer, expect to pay $10-$20.
However, if the leak is because of a damaged rim, you’ll incur more costs which vary greatly depending on the brand.
If you check popular online sites, rims’ prices range from under $25 to $200; therefore, it will cost you more to repair the leakage if you have to replace the rim or entire tire.
To avoid this tire leak, there are some preventive measures that you can take.
Regular Maintenance
As mentioned above, tire leakage can result from valve stems or rims that are dirt clogged; therefore, you need to check your tires regularly.
With more accidents connected to tire blowouts and issues, it’s safer to have your tires checked for any potential problems to prevent leaking around the rim.
Drive Carefully
We have already established that punctures are the number one cause of tire leakage; therefore, if you can, it’s best to avoid situations that could cause punctures.
To achieve this, you should drive more carefully and at recommended speeds, especially on roads with potholes or speed bumps.
Avoid Overinflating Tires
Overinflating tires doesn’t solve a tire leakage problem. Once you identify that air is leaking around the rim, follow the above steps I shared to fix the issue.
However, if you choose to overinflate, the tires will become unstable, rigid, and lose traction when you are driving.
Use A Professional Mechanic
According to the U.S. Tire Manufacturers Association, drivers should supplement their monthly inspections with regular professional tire care.
The check should include wheel balancing, alignment, and tire inspection to protect your tires from leaking air.

Tires leak air around the rim for several reasons, but luckily this problem can be fixed and prevented.
While it’s possible to fix a leak at home using the kit from your car, you can also enlist the services of a professional mechanic if you spot extensive damage.
I have shared some simple steps that you can take to fix the leak, especially if you are doing it at home.
To avoid these tire problems, regularly check your tires for air pressure and damages at least once a month, consult professional mechanics, and drive carefully to avoid incurring extra repair costs.
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.
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.

A flat tire on a car is always a nuisance, especially if the pressure loss caught the driver not in the garage, but on an empty highway.
And it's not always a puncture, because the bleeding of air can occur along the disk. Why the wheel is lowering along the rim and what to do about it, we will analyze in the article.
This problem is quite common with tubeless tires, where the rubber adheres to the disc due to internal pressure. At the junction of the disk and tire, the seal is sometimes broken and air is bled, which ultimately leads to a complete loss of pressure. In chamber tires, the situation is more unambiguous: if the wheel is flat, then look for a puncture.
Deformation is the main reason. Disc geometry is an extremely important thing for full-fledged work, sometimes even a dent in an insignificant place can be fatal. The car drove into the pit - the disk bent, the tightness of the cord was broken and all the air came out. Low temperatures outside the car, which causes the rubber to harden, is a common cause, especially if tightened with a tire change. Also, due to poor maintenance, improper storage of the prefabricated kit, or constant driving on roads sprinkled with reagents, the disc begins to rust, as a result of which corrosion eats away the metal, forming micro-holes through which air will be gradually etched.
Blowing off the wheel can also occur through a faulty nipple.
In the end, the reason that the wheel is going down is the most banal - the rubber is already old and deformed over time, which means it is physically unable to provide the desired density at the point of contact. There is nothing to prevaricate here: the tire urgently needs to be replaced.
It would seem that since such a disaster does not happen with chamber tires, isn’t it better to give preference to them? Maybe in this sense this is true, but in fact, tubeless has more than one advantage. Here they are:
They have no friction between the tube and rubber, which means that the tire heats up less during long rides.
It is lighter and more reliable, since the chamber version can burst at high speed.
It balances better and holds pressure longer after a puncture.
A hole in the tread may not interfere with the ride at all - a stuck nail will simply not allow air to escape.
With a chamber tire, this is impossible, it will be blown away pretty quickly.
Damage to the tread can be urgently repaired with a repair harness. This is quite enough to get to the nearest tire center and change tires.
First, make sure that you do not have a puncture in the wheel or that the cause of the trouble is not in the nipple. It is elementary to notice a protruding nail, but it is not always necessary to pull it out immediately and immediately. As we wrote above, a foreign object can simply get stuck in the tread and the air will have nowhere to go. An open puncture is repaired with a tourniquet.
The valve must be smeared with soapy water or simply slobbered - if there are no bubbles anywhere, then it has nothing to do with it. A defective nipple will have to be replaced with a new one.
If the valve is in order, fully inflate the tire and smear the edges of the cord with soapy water. You can do this with a brush or use a sprayer.
Air bubbles will tell you that the source of the trouble is in the detachment of the cord from the disk surface, i.e. in violation of the tightness of the tire seat. Metal edges should also be carefully examined - any cracks and welding defects can be the cause of a pressure drop.
To eliminate the descent from under the rim, you can do this:
We poison all the air and remove the wheel from the car.
It is best to disassemble it, so it will be much more reliable to fix the problem. In order not to do the balancing again after the procedure, it’s a good idea to mark the position of the nipple with chalk first.
The disk edges will have to be properly sanded with fine sandpaper in places of rust damage and covered with a new layer of paint.
After the paintwork has dried, we put the tire back on and spread the rubber on the places where the cord touches the disk with a special sealant or mastic. Or you can use the soap solution again, but this time cook it much thicker so that it resembles glue in viscosity.
And with the help of a simple brush, we go around the entire circumference of the cord on both sides of the wheel.
We inflate the tire with a compressor, pressing the cord against the disk.
So we will eliminate the damage and provide a tighter fit on the seat. The sealing compound must penetrate all micropores and prevent new bleeding of air.
If there is absolutely no time to remove the wheel, and trouble overtook you on the road, it is enough to bend the edge of the cord and also smear the rubber with sealant or soap. This is quite enough to reach the garage or car service.
The described methods are suitable if there was no serious deformation and there are no cracks in places near the mounting holes or there is no damage to the tire cord. In the worst case, you can’t do without rolling a disk in a tire fitting or replacing it. If you have an alloy wheel, then you can fix it, but this is an extremely expensive business, comparable to buying a new one.
However, even when repairing at a tire center, rolling a casting does not always help, and it may soon crack. It’s better not to even think about repairing the wheels yourself. A mistake can be costly. It is often much cheaper to buy one than to repair it. The assortment of the BlackTyres online store includes inexpensive models from Russian and foreign brands. Browse the catalog and choose what you like. If the matter is not only in the disk, but also the rubber fails, spending money on repairing both of them is a waste of time. Now wheel assemblies are extremely popular. One such set will cost you 10% cheaper than a collapsible version. In addition, due to it, you can significantly save on the cost of tire fitting, since mounting and balancing of the complete wheels is not required.

, and the specialist in tire fitting did not find visible punctures, cuts or other damage to the rubber.
What could be the reason for the depressurization of the wheel in this case, and how to determine it, the AvtoVzglyad portal figured out.
Ivan Flyagin
The vast majority of modern cars are equipped with tubeless tires, which allow maintaining pressure in the wheel for some time with a slight puncture. That is why, unlike tires with a chamber, which, if damaged, can instantly go down or even burst at high speed, such rubber is considered the safest.
Most often, tires are blown out due to a puncture or side cut, but sometimes the driver does not find visual damage on them, and in order to determine the cause of depressurization, he turns to the tire shop. Even if it happens on a trip, far from home in an unfamiliar area, it is still better to replace a flat tire and not hesitate to diagnose and repair it. The use of various tire sealants in this case will give a temporary effect. But, first of all, it is necessary to establish the cause of tire depressurization.
What does the specialist do in this case? To begin with, he usually pumps the wheel 1-1.5 atmospheres and tries to catch by ear where the air comes out. If there is no result, then most likely, he will moisten the surface of the tire with plenty of soapy water and determine the location of the damage by the emerging air bubbles.
But even this sometimes does not help, and then the wheelmaker will dip the entire wheel into a tank of water. Alas, even in this case, there may be no bubbles, since it happens that the removed wheel holds air, and if you install it on the car, it lets it through. This is mainly due to an object stuck in it - a self-tapping screw, a nail, a piece of wire. One effective way to solve the problem in such a situation is to disassemble the wheel and run a rag over the inside of the tire. If the rubber caught some sharp object, then it will definitely stick out from the inside, and the rag will catch on to it anyway.
If the master has not been able to find damage to the rubber, then the wheel can be lowered only in two cases - due to a disc failure, or due to depressurization of the spool (nipple).
