What to do if a flat tire?
Most cars produced today are fitted with tubeless tires, but that doesn’t mean the vehicle owner won’t have to deal with deflation. Agree, this is a fairly common and unpleasant problem that requires an immediate solution.
Flat tires, looking for reasons
Surely more than one driver wondered “why does he lower the wheel?”; in fact, there may be several reasons for such a nuisance. For instance:
A tubeless wheel can leak air as a result of the normal puncture of the tire tread, caused by hitting a nail, wire, or sharp stone. In fact, this is a fairly minor damage, and in most cases the driver will be able to get to the tire service.
An equally common cause of this phenomenon is also a cut (it can be both lateral and along the central part of the tire). Damage to the central (running) zone is rare, as it is rarely possible to cut through such a thick layer of rubber. It is much more common to see a side cut resulting from close contact with the sharp edges of a pit, parking lot wall or road curb.
Deformation of the disc can cause the wheel to deflate, as a result of which the place of contact of the bead of the tire becomes leaky. In most cases, the deformation is caused by the poor quality of domestic roads or by the inexperience of the driver (for example, when the front wheels have already turned when turning, and the rear wheels drove along the curb). Disc straightening can help to solve this problem, which does not in any way affect the condition of the rubber itself.
Spool leaks are another reason for deflating the tire. There are two design options for this element: long and short. In the first case, the spring rests against the lower part of the nipple, while in the second it is located in the spool itself. Despite the fact that there is not much difference between these details, preference is still given to short elements.
Air leakage from under the nipple (valve), in the place of its attachment to the disc, can also be considered the reason for tire deflation. In this case, to eliminate the problem, you will need the services of tire specialists, since you will have to change the valve itself.
It is impossible not to remember driving on flat tires, because such “chewing” of rubber leads to the formation of cracks, and they, in turn, contribute to air leakage. Of course, the problem will remain unnoticed for some time, but ultimately it will still have to be solved somehow.
In some cases, it can be very difficult to find a specific answer to the question “why the tire is deflated on the car”. Even tire specialists do not always know what the matter is. In this case, the following can help: pump the wheel 1-1.5 atmospheres more and lower it into the water. Outgoing air bubbles will tell you where the damage was.
If you cannot find an object stuck in the tire, then you can use the “old-fashioned” method of finding it: disassemble the tire (it is better to completely remove it from the rim) and run a regular rag along the inside of the tire. If there is even the smallest protruding object, the rag will catch on it.
Why does the wheel flare
Seeing (or feeling) that a favorite car has skewed due to a broken tire, every driver is in a hurry to find the source of this problem. The main reasons for deflating the wheel:
- The most common option is a tire puncture. This happens, as a rule, due to a run over a nail, wire and other small metal objects. If, due to a puncture, a tubeless wheel is deflated, it is often possible to drive to the nearest service station with periodic pumping up, and sometimes even without them.
- Another fairly common problem is wheel cut. If the puncture in most cases falls on the tire tread, then the cuts are also lateral. A cut of the tread (tread) is rare, since it consists of a rather thick and dense layer of rubber. Much more often this problem occurs on the side of the tire, which is much thinner. This happens on contact with sharp objects. These can be the edges of the track, curbs (from which metal reinforcement often sticks out) and other protrusions. If the cut has not reached the court, then the wheel will usually not deflate. But if the rubber is cut deep, then you will learn about it much faster than about a puncture, since the cut surface is larger. Unfortunately, if this problem happened on the side of the wheel and caused serious damage to the rubber, then most likely it will not be possible to fix it.
- Sometimes the wheel deflects due to deformation of the disc, which leads to depressurization of the place in which the tire adheres to it. The disc can be damaged either due to poor road surface, or due to the inexperience of the driver (disc hitting the curb during parallel parking and other oversights). Straightening the disc helps to solve this problem without harming the tire itself.
- Depressurization of the spool or nipple (valve) is another reason why the wheel is often deflated. This happens either due to mechanical stress on these elements or due to their inaccurate installation. The second reason is more common, since it is rather difficult to hit the nipple with the spool, because it “hides” behind the disc. By the way, spools are available in long and short designs. The first option, as practice shows, is more reliable.
How to keep a car on the road in case of a sudden breakdown
There are times when on the road, for no reason at all, the wheel is deflated. What to do to stop the car safely? Let’s analyze it step by step:
- First of all, it is worth noting a simple fact. the slower the car goes, the more likely its passengers will remain unharmed when the wheel is abruptly lowered. Therefore, when breaking the speed limit, remember this.
- If the wheel drops sharply (you will certainly feel it), do not rush to press the brake into the floor. The subconscious mind will force you to slow down in any emergency, but this is the worst thing that can be done in this case. If you brake, the car will drive even more.
- If you have cruise control turned on, turn it off as soon as possible.
- Do everything to keep the car on a straight line. If it leads to the side, turn the steering wheel in the opposite direction. But do not overdo it, otherwise you will get the opposite effect.
- Let the car drive to the stop on its own. The car will brake itself, due to a flat tire. You can help her by lightly pressing the brake. It is best to brake with the transmission in this case. If there is no roadside nearby, do not stop on the road, it is better to drive some distance on a disk. Remember to turn on the alarms so that other participants are aware of your problem and are careful.

Flattens the wheel: what to do, problem solution and professional recommendations
Every motorist knows that a flat tire in a car is a rather unpleasant, and in some cases even a problematic situation that requires a quick solution to restore the car’s performance. Today we will discuss in detail the issues related to a puncture of a wheel, find out why this problem occurs, as well as how to solve and prevent it.
What to do to prevent the problem
Any problem is much easier to prevent than to fix. As mentioned above, in most cases, a modern tubeless tire is punctured by a sharp object and does not immediately begin to descend. So that the active phase of this very descent does not take place on the road, when a protruding nail, for example, gets caught on something, you need to inspect the tires daily and measure the pressure in them at least once a week.
In order not to puncture the wheel, try to avoid dangerous areas (construction site, old tram tracks, badly bumpy roads, and so on). If it happens that you notice an obstacle, but do not have time to go around it, do not turn sharply. The center of the wheel is much thicker and denser than the side, so it is better to drive straight into an obstacle.
What should be in the trunk
Be sure to carry your pump and repair kit with you! The wheel can lower at the most inopportune moment, so it is better to be prepared for this. Of course, nobody canceled the spare tire either. If it so happens that you have neither a spare wheel nor tools, a simple self-tapping screw will come to the rescue. It must be screwed tightly into the puncture site. With a self-tapping screw, you will most likely be able to get to the tire fitting. You can always find a self-tapping screw in a car, most importantly, do not forget to return it to its place later. Thus, the minimum tool you need to repair a wheel after a puncture is a screwdriver. But it’s better not to mess with such methods.
The above tips for a quick self-repair of a wheel are relevant only in the event of a puncture. In case of cuts and other problems, only a spare tire can be a salvation. In the garage, you can already try to glue the tire with special patches, similar to those used when deflating a wheel on a bicycle or motorcycle, but it is better to turn to professionals.
Deflates or deflates a wheel. what to do
DO NOT CONTINUE DRIVING ON A FLAT TIRE!
Riding on a flat tire will quickly ruin your tire. Without any air support inside the tire, the sidewalls of the tires will be trapped between the road and the edges of the wheel rim, and even a short distance (say over 1/2 mile) can be enough to cut or destroy the tire. And if the tire comes off the rim, which a flat tire can do, you can damage the wheel too.
Why you can’t limit yourself to repair with a flagellum
The fact is that, wielding a spiral awl, there is a great risk of causing fatal damage to the tire. An inexperienced car enthusiast or even a service technician may inadvertently break the cords. These damages are difficult to notice, but they lead to the fact that the tire casing simply begins to “float”. That is, the life of the tire is reduced to a minimum. The geometry of the tire is disrupted very quickly, “hernias” grow, and the wheel can explode altogether.
The greatest danger is if the manipulation of the awl has resulted in damage to the steel cord. If such threads break, they will create a network of channels invisible to the eye, through which air will escape. It is impossible to repair such damage, even if you use the most expensive miracle sealant. After a while, the tire will begin to flake, and after 100-200 km it will become completely unusable (or earlier).
The flagella themselves bring troubles. Yes, they are able to withstand more than 2 atm, it is true. But, this ability is temporary. After a while, repair cords will inevitably begin to leak air.
It is also worth paying attention to the flagella themselves. Some of them become useless after a few kilometers of movement. Therefore, you need to carefully choose repair cords:
- Synthetic fiber flagella (one-piece). Such products are the cheapest, but in a professional environment they are considered absolutely useless.
- Rubber impregnated. These are high-quality products, but the common man does not always manage to cope with their installation. Very often, such cords break if handled incorrectly.
- Cordovye. They do their job well, but, again, if installed by a layman, then their use can lead to rubber delamination.
Based on this, when you repair yourself, the probability of damaging the tire is too high. Therefore, it is best to immediately go to the tire fitting, where the master will be able to assess the condition of the tire and repair it.
Tire repair tools
You should always have a set of tools in your trunk that you can use to fix a punctured wheel or an internal tire pressure leak:
- jack and safety platforms;
- straightening hammer for straightening dents or removing nails from rubber;
- winch or cable for towing the machine;
- torque wrench;
- wrenches and screwdrivers;
- pump or compressor;
- set of socket heads with wrench.
An emergency sign must also be included. You will need it to mark the car on the side of the road if you need to stop for repair or replacement.
What to do if the wheel is flat
On the road, you can quickly punch a car wheel, at the end of which the subsequent movement is unrealistic. In the provided article, we will tell you what to do when the wheel of the car is deflated, and how much you can “ride” on the punctured rubber.
If your tire is badly deflated, first try inflating it using a transport compressor. Such structures are desirable for any driver, since they can help to pump up the wheel if there is no alternative option or you are far from the city (in a village or on a deserted highway), and their price is insignificant.
After the car wheel is inflated, listen to the noise it makes. If the wheel is punctured or there is a cut, then you can hear the whistle of the released air from it. Plus, before this, a drop in pressure in the wheel when you pumped it up to maximum is considered an obvious sign. “Sentence”, after the tire is deflated extremely rapidly and it will not be possible to continue driving. this is either a change to another wheel or to get to the nearest car service.
What to do if a flat tire on the road?
First of all, you need a spare wheel to change a wheel, so you should give up toroidal gas cylinders, and ideally, stowaways. It is also highly desirable that the type of tires on the standard wheels and the spare tire are the same: summer in summer and winter in winter. In this way, it will be possible to protect against possible handling problems caused by different levels of grip between the wheels. As a rule, they develop suddenly and can lead to consequences much more serious than a simple tire fitting. Therefore, when going to buy a new set of winter or summer tires, you should budget for five units.
How to Fix a Flat Tire on a Bicycle
It will not be superfluous to conduct a little self-preparation: find and remember the location of the sites provided by the manufacturer as a stop for the jack. These pads are stiffer and more durable than the metal of the car body panels and it is important to understand that by installing the jack in an unsuitable place, there is a serious risk of damage to the underbody and sills. You can find out about the location of the sites from the instructions for the car, or ask the specialists of the tire center about it during a scheduled tire change.
In addition to a spare wheel, a key, and a working jack, it is recommended that you carry a few things with you to make changing a wheel easier. A powerful flashlight is invaluable at night, work gloves made of dense fabric will protect your hands from skin damage from contact with asphalt. A hand or foot pump will help with pumping up the spare wheel. the last time it was pumped, at best, during a scheduled tire fitting. A couple of extra wheel bolts can come in handy if one of the standard ones gets lost in the dark, and a vest or raincoat with reflective stripes makes you visible to other road users. As a rule, tires are replaced right on the sidelines, and in Ukraine they are often not covered.
It must be remembered that the procedure for changing a wheel with a jack is dangerous and in the process it is necessary to adhere to certain rules. Before using the jack, the car must be applied to the handbrake, and after lifting, make sure that it is securely fixed and does not jump down. And in no case should you try to fix the jack if the body is already supported on it.
Nokian Tires strives to make summer and winter tires as reliable and durable as possible. To reduce the risk of cuts, the sidewalls of some models, especially for SUVs and crossovers, are reinforced with aramid fibers. Aramid, better known as Kevlar, is also used in the space industry, in the production of body armor and is not inferior in strength to steel. In the Nokian Tires summer tire range, aramid fibers are present in the sidewalls of models such as the Nokian Hakka Black 2 SUV and Nokian Hakka Blue 2 SUV.
In addition, at Vianor tire centers, our customers can count on expert advice. Vianor specialists will show the platforms for the jack support and give recommendations for safe wheel replacement in the field.
