What is Tire Repair?
Tire repair refers to the process of replacing a faulty tire with a new one or simply repairing a tiny puncture. While it sounds like a job anyone with two hands can handle, it’s recommended to go to a shop that specializes in repairing tires to ensure that you get your problem solved completely.
Why You May Need Your Tire Repaired?
Years ago, car owners frequently dealt with the superfluous hassle of repairing their tires due to the quality. Thanks to the manufacturers and present day technology, tires are meant to withstand even the worst conditions on the road. While this holds much truth, it is not uncommon for people to find themselves needing to have their tire(s) repaired due to weather or other hazards on the road.
How Much Will A Tire Repair Run You?
While a tire repair won’t cost you an arm and a leg, it will cost you a bit of your time. If you’re looking into having a puncture repaired on a tire, you’re looking at spending on average between $10 to $20 dollars. The size of the puncture makes a huge difference and will determine the amount you will spend on getting your tire repaired.
Important Facts You Should Know About Tires
What Process is Used When Repairing a Tire?
A tire plug is exactly what it sounds like; a sticky expandable plug that is inserted into the puncture in hopes of keeping the injury secure long enough for the tire to re-inflate with air.
A patch is also pretty self-explanatory when it comes to description. Better known as a radial patch, this piece of material is used to seal up the damaged tire. Due to the heat caused by driving, the patch eventually melts into the tire completely erasing all notices of repair.
Most vehicles are equipped with a spare tire if you happen to be running on a flat. In some cases, you might have to go to your local car shop to purchase a tire depending on the circumstances.
The Difference Between a Plug and a Patch
While the plug takes less time and can be down without removing the entire tire in comparison to the plug, it’s more likely for a car owner to come back in a shorter amount of time for yet another repair after getting a plug opposed to a patch.

Tire patches are a huge money maker for auto shops.
They don’t require much labor, and the cost of a patch is really low compared to most other auto parts.
But what is a good price to pay to get a tire patched? Well, that depends. If you patch the tire yourself, expect to spend $6.00. If you take it to the shop, you’re looking at spending anywhere between $10-$40, depending on the situation.
Patching tires yourself is always everyone’s first instinct, since the cost is so low. But many people are deterred when they find out they can’t, due to any number of reasons. Deciding when to do it yourself, versus taking it to the shop is what we’ll explore in this article along with why tire patches can be so pricey. We’ll outline the different reasons you should, or shouldn’t do it yourself. We’ll also examine the different types of patches and the pros and cons of each.
I used to work at a shop on a main highway. Every day, during rush hour traffic, at least 3 customers came in requesting a tire patch. Over the years, I’ve learned the simplicity of the tire patch can be deceiving.
Not all tires are created equal and the same goes for patches.
When a shop patches your tire, most of the cost stems from the mechanic’s time.The wholesale price of a tire patch is less than $2.00. The glob of bead sealer that’s used to seal the patch costs less than $0.10.
But it takes the average mechanic about 15 minutes to patch a tire. Most shops charge around $120 per mechanic hour, so you’re looking at $30-$40 for time and parts. If you want the tire re-balanced, as is recommended, tack on another $13.00.
While a tire patch is among the most simple jobs, it takes time away from mechanics who could be working on higher paying, more demanding jobs. Hence, the hourly rate being applied to the job.
Not all tires can be repaired. There are some tests that mechanics, or you yourself, can perform. Doing these tests will give you a good idea as to whether or not your tire can be repaired.
When your tire becomes flat, the first thing to do is not drive on it.
Driving on a flat tire, even for a short amount of time, can damage it beyond repair. When a tire is operated without air, the vehicle’s weight crushes the tire’s innards turning it to dust.
The next thing to do is see what caused the flat. Nails directly in the middle of the tread are a common occurrence. They can be easily spotted from a distance. If you can’t see it, running your hand around the tread will reveal the location of the nail.
Tire punctures that occur within 2 inches of the sidewall are considered non-repairable. This means neither you, nor the shop, can repair this.
It’s actually against the law for auto-shops to repair tires that have punctures close to the side wall. The issue is, tire patches placed close to the side-wall often result in tire blowouts, due to the shifting nature of a tire’s sidewall to tread relationship.
A good test to measure the distance between the puncture and the sidewall is to place your thumb in that space.
If the puncture is a thumbs width (or more) away from the side wall, you’re in the clear.
If not, sadly, it’s time for a new tire.
The length of the puncture is the next thing to look at. Most nail punctures are just as wide as the nail itself. In this case, with the puncture being so small, it’s ok to plug the tire yourself. But if the length of the puncture is 2 ½ inches or more, you cannot patch it.
You cannot patch it, or a shop cannot either. Punctures this large are not repairable, because patches aren’t meant to hold in air over that big of an area.
The inner tire liner doesn’t become fully sealed, even with the largest patches available. If your puncture is more of a gash in the tread, it’s time for a new tire.
Fully patching a tire requires you to complete the following steps.
So as you can see, the full, official way to patch a tire is quite involved. This is why you can see prices up to $45.00 for a simple patch.
If the tire has to be rebalanced, that’s around $13.00 and if it needs new valve stems, or a TPMS sensor, this can also tack on extra costs.
This patch is so effective that it saves you from having to purchase a new tire. You can enjoy the full length of the tire as if no puncture ever happened. Patching a tire can be quite the life saver when you’re in a jam.
The obvious issue here is that tire machines aren’t commonplace in the average driver’s house. So doing it yourself this way isn’t really feasible, but the method we discuss next can be done almost anywhere.
Tire plugging is a simple fix applied to various types of tire punctures. The majority of tire punctures can be repaired by doing a plug yourself.
To plug a tire, just push the plugging strip with the T-Handle in as far as it will go. Then, with all your might, quickly pull the t-handle out. This will plug the tire, and all that’s left is for you to cut the excess plugging strip away.
Tire plugging is looked down by Tire Shops because they consider it not fully seal the surface. But I’ve plugged well over 500 tires, and have never had an issue. Most independent shops are fond of tire plugging as well, since it keeps prices down for them, and the customer.
Tire plugging can be done by yourself, in your driveway. If you don’t feel comfortable doing it, call up an independent shop and ask if they plug or patch tires. Most likely, they probably offer both, but they’ll charge half for a plug, compared to what they would for a full patch.
Plugging tires, while usually a simple task, can turn into a complex issue.
For example, if you plug a tire, and you can still hear a slow hissing noise, it can be a pain to hunt down the source of the leak.
Or if you spray the whole tire down with soap in order to locate the leak, and can’t find it. You might start to question your sanity. Don’t! These issues can take up hours, even for master techs.
There’s actually a machine in some tire shops that puts the tire under water using a crane-like object from above. Even this machine still fails sometimes, and mechanics are left scratching their head. So if you start to encounter any issues of locating the leak, or plugging a leak, it’s time to take it to the shop.
If the tire is totally flat when you walk out to your car, you should be able to use your spare tire, and repair the issue at home with a plugging kit. But if you plug the tire, and it’s still leaking, take it to the shop and let them repair it.
If you are questioning the length test or edge test results, it’s also recommended that you take it to the shop.
Some mechanics will say, “use double the amount of plugs”, to fix large gashes. This is wrong. If one plug can’t fix it, take it to the shop and see what you can recoup.
But for the majority of situations, where a nail has punctured your tread somewhere in the middle of the tread face, it’s totally acceptable to purchase a plug kit, and do the repair yourself. It will save you a couple bucks, and you will have had the opportunity to go under your car to do a quick visual inspection. Or take off the tire and glance at the brake pads.

Experienced drivers are not surprised by such a trifle as a puncture, but for the first time beginners usually get confused in the sequence of actions, forget about important details and do not know what to do with a punctured wheel even in a tire shop - especially if they start offering choose from several options or intimidate with expensive repairs.
Let's set up an operation algorithm when a flat tire is detected and figure out what to do right away and what to choose later.
What to do when you find a puncture
Having found a flat tire, first of all you need to stop in a safe place, turn on the emergency alarm, assess visibility and, if necessary, set an emergency stop sign: according to traffic rules, it is installed at least 15 meters from the car in built-up area and at least 30 meters outside the built-up area. When choosing where to stop, consider the space to the side of the vehicle to handle a flat tire. You should not stop right on the road and in places where stopping and parking are prohibited: even if a punctured wheel belongs to the conditions of a forced stop, it is quite possible to drive several tens of meters on it to choose a safe and convenient parking place. At night or in conditions of limited visibility (for example, in fog or rain), it is imperative to wear a vest with retroreflective elements - this is required by clause 2.
3.4 of the SDA and common sense.
Now you can start working on the wheel. We will sequentially consider several options for action, and then move on to ways to repair a damaged tire.
The most obvious solution to a flat tire is to replace it. If you have a spare tire that you are sure is in good condition, the best option is to install it and visit a tire shop to repair a punctured tire - such repairs will be more reliable and of high quality than doing it yourself.
If you don't have a suitable spare tire, but you do have a pump or compressor, you can assess the damage to the tire and try to pump it up again to get to the tire shop. It is better to start searching for an air leak with a valve (aka “nipple” or “nipple”): often a faulty spool becomes the cause of a flat tire. It is easy to check it: unscrew the protective cap (if there is one), pour water on it (or slobber it, as in childhood): air bubbles will leak. In this case, you can try to replace the spool valve by unscrewing it and screwing in a new one, but if there is no new valve, as well as a store nearby, you can try just unscrewing and screwing it back in.
Regardless of whether it helped or not, you need to visit a tire shop to replace the entire spool or valve.
If the valve is tight and the tire is flat, it is most likely a puncture. The easiest way to find a puncture that is free of foreign objects is to pour water on the tire while looking at the surface: the damage will reveal itself as air bubbles. However, often the cause of the puncture can be found along with it: a self-tapping screw, nail or other arbitrary object sticking out of the wheel will clearly indicate the place of depressurization. In this case, you do not need to immediately remove the foreign object from the tire: it partially seals the hole, and if the pressure loss is slow, you can try to pump up the wheel and drive to the tire shop.
The same goes for wheels that are leaking from the rim or from a faulty valve. Usually, in this case, the air is bled slowly, and you can pump up the wheel and have time to get to the place of repair. By the way, rim leakage can occur due to disk deformation upon impact - for example, when hitting a pit with sharp edges.
Such situations are fraught with damage to both the disk and the sidewall of the tire, in which case the disk will need to be corrected, and the tire repaired or even replaced. To avoid rim leaks, you need to inspect the rims every time you change tires. The loss of tightness occurs either due to corrosion or due to disc deformation, and not only steel, but also light alloy wheels can corrode. So if you see paint blistering or rust on the rim, the tires need to be put on rim sealant: when changing tires, this will be cheaper than the subsequent removal and re-tire to fix a leak on the rim.
If you find a puncture, but there are no foreign objects in it, and you do not have a spare wheel and tire repair kits, there is another popular method of temporary "repair". You can screw a self-tapping screw into the found hole - if, of course, you have one. In extreme cases, you can look for a self-tapping screw in the cabin by unscrewing it from some interior detail. This method cannot be called reliable: it is unlikely to ensure complete tightness of the wheel, but at least it can help you get to the nearest tire shop.
And a couple more useful remarks. If the wheel is completely flat, then it is easier to inflate it without a spool: the latter must be unscrewed, then the tire must be inflated and quickly screwed back in. The fact is that the spool itself, when inflated, resists the compressor, and in the event of a loose fit of a flat tire to the disk, the power of a simple magazine compressor may not be enough, and the absence of a spool helps to increase air flow and facilitate the operation of the compressor. If this does not help, you can jack up the car by hanging a flat tire: this will improve the fit of the tire to the disk, and the chances of inflating the tire will increase.
On-Site Repair Methods
Now let's look at options for repairing a tire yourself using special materials that you should carry with you or, if a puncture caught you in the city, buy it at the nearest auto shop.
1. The most common, cheapest and easiest way to do it yourself is to install a raw rubber band.
The harnesses are sold complete with an abrasive awl to expand the hole in the tire and improve the contact of the repair harness with its edges, as well as a needle for installing the harness and an adhesive to fix it and at the same time seal the puncture. When choosing a repair kit in a store, you should pay attention to the following nuances:
Install the harness in the following order. First, the found hole is expanded with an abrasive awl - you need to insert and remove it several times into the puncture site. Then the tourniquet is inserted into the eye of the needle, and glue is applied to it. After that, the needle with the tourniquet must be inserted into the hole in the tire and pulled out sharply - so that the tourniquet remains in the hole, and the needle comes out without it.
If everything worked out, it remains only to cut the end of the harness flush with the surface of the tire and pump up the wheel.
The advantages of repairing with a harness are quite decent reliability, simplicity and low cost. On a well-repaired tire, you can drive for a long time, and if the repair site starts to poison, you can either replace the harness or have the tire repaired in a quality service. Among the minuses is the possibility of damaging the cord during installation, as well as lower reliability compared to “full-fledged” repair methods in a tire shop. Strictly speaking, a tourniquet is still a temporary repair, so if it is possible to pump up a wheel and get to a tire fitting, then it is better not to enlarge the hole in the tire and get to the experts.
2. The second repair option is aerosol liquid sealants sold in cans. To repair a punctured tire with sealant, you need to remove the foreign object from the puncture site, then pour the sealant into the wheel through the valve, twist it to distribute the composition inside the tire, pump up the wheel and drive several kilometers at low speed for the final uniform distribution of the sealant.
Among the advantages of this repair is the simplicity and less labor intensity compared to installing a harness. However, there are also disadvantages: the larger the hole, the higher the chance that the sealant will not be able to eliminate it, and such a repair can affect the wheel balance. Compared to a tourniquet, it can be considered even less reliable and preferable, but simpler.
Repair options at a tire shop
If you put on a spare tire and brought the wheel to a tire shop, you may also be offered several repair options. Consider the most popular with an indication of the advantages and disadvantages.
1. The first repair method is the same harness installation as described above. As we remember, the tourniquet refers to a temporary repair, so among tire specialists this method is considered bad form, but many workshops do not exclude it from the list of services. All the advantages and disadvantages are the same here: such a repair will be the fastest, simplest and cheapest, but less reliable than other methods.
It is worth choosing it in cases where the price and / or speed of the procedure is more important to you than anything else. If quality is a priority, then it is better to fork out for the options listed below.
2. The second option for repairing a puncture is to install a patch on the inside of the tire, the so-called cold vulcanization. In this case, the tire is removed from the disk, the surface around the puncture is treated with an abrasive, and the damage is sealed with a special patch. This is a more preferred repair method than a tourniquet: it is more reliable and durable, especially in the case of side punctures, when not the thick tread part of the tire is damaged, but the thinner sidewall. Among the minuses, only a higher cost can be noted: in addition to the actual tire repair, you will have to pay for the removal and installation of the wheel (or do it yourself), tire fitting and balancing.
3. The third option is a "complex" of the first and second: installation of the so-called repair "fungus".
The “hat” of the fungus is a patch, and the “leg” is threaded from the inside of the tire to the outside. After gluing the patch, the excess part of the leg is cut off, as in the case of the tourniquet. Thus, not only the inner surface of the tire is closed, but also the hole itself. The advantages and disadvantages of this repair method are generally the same as those of a patch.
4. An extreme, “emergency” measure when repairing a punctured wheel is to install a camera in it. Typically, this method is used for tires that are no longer worth repairing, or “for reliability” after repairing a complex puncture. It should be understood that almost all modern tires are tubeless, that is, they are not designed to install a camera, so it’s not worth driving a wheel repaired in this way for a long time. Installing a tube is a temporary solution for riding until a new tire is purchased, and sometimes such wheels are left as spares. So this repair method can be kept in mind as a backup.
Finally
We have deliberately left out of this text such methods as combined repair of tires with a tourniquet and a patch and hot vulcanization. The first is used quite rarely and for specific damage, and it is enough just to know about its existence. Well, the second is used to repair serious side cuts, and it is not only rare, but also very expensive. The cut site in this case is prepared, filled with raw rubber and processed with a hot press for vulcanization. Equipment for this procedure is not available in every tire shop, and the cost of repair can be about half the cost of a new tire.

You have never seen such tires: even the police were surprised
In the process of using the 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 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.
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 curbstones 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.
