How To Inflate A Completely Flat Car Tire | CarShtuff

‍The best way to avoid getting stuck or stranded with vehicle troubles is to learn how to inflate a completely flat car tire without damaging it.

When your car tire goes completely flat, it presents a few risks to your vehicle, and inflating it can be tricky for someone with little experience. Fortunately, getting this fixed is not overly expensive, assuming the tire is still intact.

You can use an air compressor to inflate a completely flat car tire unless the steel bead has pulled away from the rim. If this happens, you need to take the tire to a repair shop for them to adjust the valve stem to inflate the tire again correctly. This can be done manually or at a gas station.

A completely flat car tire can present serious issues for many vehicle owners because if you allow this to sit idle for too long, damage can happen. It is best to inflate this tire as soon as possible. We will show you exactly how to do it in this guide.

The car tire is a complex and fragile part that is often the first to go on most cars. Understanding how to inflate it when they go completely flat is critical.

‍How To Inflate A Completely Flat Car Tire

You must know how to properly inflate a completely flat tire because this likely means you are stuck where you are. Unlike when a tire is low on air pressure, a completely flat tire cannot drive any further.

If your car tire is completely flat, you need to fill it with air. This is not an easy task and can be dangerous if you do not know what you are doing.

You need to use the right tools to inflate the tire. This can be done with a local air pump at a gas station, or you can use an air pressure gauge and portable air compressor to get the job done.

The process starts with removing the valve stem from the wheel, then connecting the inflation hose. After that, you can begin pumping air into the tire by turning on the inflator.

If you have never done this before, a few things can go wrong. It's best to call for help from someone who knows what they're doing. Follow these steps to fix your tire.

Check The Tire’s Steel Bead

The steel bead is the first thing to do when you notice your tire is completely flat. If this bead or belt has pulled away from the rim, you likely need to seek professional help to repair your tire.

When this happens, the tire gets warped, restricting your ability to access the valve stem. Without the valve stem, inflating the tire is impossible.

Locate The Tire’s Valve Stem

If your steel bead is intact, you should have no problem inflating your tire. You should locate the tire valve stem and remove the valve cap.

Connect The Compressor Pump

Once you remove the valve cap, connect the air pump or compressor pump to your valve stem. This will start inflating your tire, and if you use an industrial pump at a gas station, it will give you live PSI readings.

Close The Valve Stem

Once the tire reaches the desired PSI level, you can disconnect the compressor pump and put the valve stem cap back. This keeps your tire sealed to preserve tire pressure while driving.

We recommend taking your tire for inspection after inflating it to ensure there is no serious damage.

How Long Does It Take To Inflate A Completely Flat Car Tire?

The time it takes to inflate a completely flat car tire is dependent on the type of tire and the size of the tire. The current PSI level also matters, and the method for inflating the tire impacts the time it takes.

It generally takes about five minutes to inflate a completely flat car tire. If you are using an industrial size compressor at a local gas station, it could be even quicker in as little as three minutes.

Completely flat usually means the tire is at 0 PSI, and this could also create a problem accessing the valve stem. Assuming you have no issues connecting the pump, it won’t take more than five minutes.

Is It Safe To Inflate A Completely Flat Car Tire?

Car tires are designed to be inflated to a certain pressure, usually around 32 psi. This will vary depending on the tire type and vehicle.

If you see a tire that has been completely deflated, it may not be safe to inflate it again because the tire could burst or lose its shape. For a tire to lose all of its air, there is likely a leak or puncture that should be fixed first.

You should also check your rims to make sure they are intact. Driving on a completely flat tire means the rims likely endured added pressure that could have caused some severe damage.

Is A Car Tire Ruined If It Goes Completely Flat?

If you have experienced a completely flat tire, don’t panic yet because it is still possible to salvage the tire.

You should bring your tire for inspection at a local repair shop to get a professional opinion. Typically, a puncture of one quarter inch or smaller can be patched unless the damage is more severe.

If your tire has multiple punctures, but they are small, patching is not recommended unless they are more than 16 inches apart.

However, more than two punctures mean the tire is ruined because there will be a lack of balance with your tire when driving.

It is best to get an opinion from a mechanic about the current condition of your tire before making the final decision on whether it is ruined or not.

Should You Replace A Completely Flat Car Tire?

The first thing to consider is whether the tire has been damaged beyond repair. If it has, then you should replace it with a new one.

The problem with flat tires is you likely need to replace more than one tire, depending on the tread depth of the other tires. You will notice uneven driving if you replace only one tire and the other tires have a tread depth lower than 4/32.

If this is the case, you can usually replace the tire parallel to the one that is flat. So if your front driver’s side tire is completely flat, you can save some money and only replace the two front tires.

How Long Can A Car Sit On A Completely Flat Tire?

Allowing your car to sit on a completely flat tire is risky because it can cause damage to the wheel and the rim. This can also ruin the tire and eliminate any chance of getting it repaired.

The maximum amount of time you should allow this to happen is 24 hours. After that, the risk of damage increases significantly.

If, for some reason, you cannot get it repaired that quickly, it is best to use a jack to raise the vehicle off the ground to take pressure off of the flat tire and exposed wheel and rim.

When you allow it to sit there for too long, the steel bead in the tire will corrode, and the rim will absorb too much pressure and begin to bend. Avoid this as best as you can and address the issue right away.

Flat tires are one of those problems that everyone experiences and no one wants to deal with. No matter when it happens, flat tires are always inconvenient, and they may even be difficult to handle. But what about repairing flat tires? How long does it take to fix a flat tire? How can mechanics tell when a tire can be patched and when it needs to be replaced? What are the signs that your tires need replacement soon? 

Don’t worry; we’ve got you covered with this article. We’ll cover how long it takes to fix a flat tire, repairable and non-repairable flats, and signs that your tire is worn out and likely to go flat soon. 

Can All Flat Tires Be Repaired?

No, not all flat tires are repairable. Tire patches only work in a fairly narrow range of situations, usually when the puncture or leak in your tire is small, smooth, and easy to locate. Other kinds of damage like rough tears, large punctures, and unidentifiable leaks may not be patchable. In fact, attempting to patch some types of damage may not just fail but also leaves your tire (and wheels) vulnerable to additional damage when the patch fails.

What Kinds Of Tire Damage Can Be Repaired?

Usually, if your tire only has one small, damaged section, like a nail puncture, your tire can be patched successfully. Even if your tire has multiple damaged areas, it might still be repairable as long as the damage is at least 16 inches apart. 

Punctures also need to be in the tread area of your tire to be repaired. Wall punctures and punctures to other areas of the tire aren’t repairable because the non-tread area of your tire isn’t as sturdy and durable. 

However, most other kinds of damage are considered non-repairable since a repaired tire will always be an increased safety risk. That means sidewall damage, large rips or tears, and tread separation are all non-repairable kinds of tire damage. Any of those problems may cause a flat tire, so if you’re wondering how long does it take to fix a flat tire, you should first ask yourself if your tire can be repaired at all. 

How Long Does It Take To Fix A Flat Tire?

Fixing a flat tire isn’t usually a difficult job. Most tires, if they are repairable, can be repaired quickly and easily. Most mechanics and tire shops can perform simple repairs, which is good since you only need to get your car to the nearest shop after a flat.  

However, you don’t ever want to rush a flat tire repair. Rushed repairs, or repairs that aren’t designed to last, can leave you in a worse situation than when your tire went flat in the first place. That’s why most mechanics don’t recommend DIY flat tire solutions; they aren’t as reliable. 

For most kinds of repairable damage, it takes about 40 minutes to an hour to repair the hole. That gives enough time to locate the damage, evaluate it, repair your tire if possible, and test the repair. 

How Are Flat Tires Repaired

Repairable tires usually have one small hole, somewhere in the tread of the tire, that’s smooth-sided and unlikely to tear further. That’s the kind of repair we’ll focus on trying to answer how long does it take to fix a flat tire.

Finding the Hole

The first step, of course, is locating the hole in the tire and making sure it’s in a repairable location and of a repairable size. What sizes are repairable doesn’t necessarily increase as your tires get bigger. That’s because tire repairs can only hold if they are relatively small, and the larger the hole is, the less stable a repair is likely to be. 

Clean the Area

The next step is to clean out the area around the hole. Flat tires are repaired with tar, so it’s important to make sure the tar bonds with the rubber of the tire instead of debris or dirt in the hole.

Scraping and Scoring

Scraping the inside of a hole in your tire might seem counter-productive, but it’s an important part of the repair process. Scoring the inside of the hole provides extra texture for the tar to bond with, making the finished patch a lot stronger. 

Sealing the Inner Liner

Tires have several different layers, and the inner layer is just as important as the outer tread. A good tire patch helps seal the inner layer, helping maintain air pressure without bubbling the tire and preventing future flats from leaks. 

Plugging the Hole

The last step in setting a patch is inserting tar into the rubber to fill the hole. The tar has to be able to reach all sides of the hole and bond with them, which is why the scoring step is so important. The patch also has to cool and set so that it’s roughly the same hardness and flexibility as the surrounding rubber; otherwise, it would crack quickly after you got back on the road. 

It’s also important to make sure the patch has similar heat resistance to the surrounding rubber. If it doesn’t heat up and cool down at a similar rate, the tar will shrink and expand at different rates, putting strain on the edges of the patch and making it much more likely to break.

Do Store-Bought Patching Kits Work?

There are quite a few different options for DIY tire patching kits that you can buy at most auto parts supply stores. However, these patching kits are rarely reliable and can be unsafe. Plug-only or patch-only repair kits don’t offer the strength of professional tire repair services. String plug repair kits are usually a little more reliable, but they still don’t offer the strength of a professional patch. 

Spray on sealants and other alternatives might be good for getting your vehicle to a mechanic or a tire shop, but they aren’t good for long-term fixes. Many sealants are only good for a few miles, which means they are best used as a short-term solution, especially when a spare tire isn’t available and a tow isn’t practical.

RunFlat Technology

The literal translation of the word RunFlat (Ranflet) into Russian means "driving on flat tires." This technology allows the vehicle to continue moving when the tire is completely depressurized (for example, due to a puncture). Different tire manufacturers refer to this technology in different ways:

The main differences between RunFlat tires and regular tires
  • reinforced wide bead ring
  • heat resistant base compound rubber
  • Reinforced heat resistant sidewall rubber compound
  • frame construction (presence of reinforcements)

RunFlat mechanism

The basis of RunFlat technology is a reinforced sidewall of the tire, which supports the weight of the car when the pressure is completely lost. Reinforced sidewalls continue to hold the RunFlat tire on the rim and support the vehicle's weight after a puncture and complete loss of pressure. It should be noted that all safety systems such as ABS, ESP, DSC, CBC, etc. remain in working order.

How long will a RunFlat tire remain serviceable after a loss of tire pressure?

All manufacturers guarantee that the tire, after loss of pressure, is able to travel another 80 kilometers at a maximum speed of 80 km/h. As practice shows, the real figures are much higher than the declared ones.

Differences in RunFlat technology from different tire manufacturers
  • composition of the technological sidewall mixture
  • mileage and runflat speed

Prerequisites for Run Flat tires
  • Tire pressure monitoring system
  • the presence of a system of exchange rate stability

Without a pressure monitoring system, running RunFlat tires is extremely dangerous. The fact is that the driver will not be able to fix the moment of pressure drop in the RunFlat tire and will continue to move without limiting himself in speed, making sharp maneuvers.

Which rims are required for RunFlat tires and can tires be changed seasonally?

All manufacturers of runflat tires accept their installation on standard rims and allow tire changes every season without any negative consequences for the tires or rims themselves.

Do I need special tire fitting equipment to install RunFlat tires?

Enough qualified installer and equipment equipped with a "third hand"

Are RunFlat tires repairable?

Repair is possible only on the tread part of the tire.

Benefits of RunFlat tires
  • Puncture safety
  • Mobility, safety margin
  • Better driving
  • No spare wheel needed

Shortcomings of RunFlat tires
  • Harder tires
  • More expensive than conventional tires on average by 15-25%

How can you notice a decrease in tire pressure?

We recommend that all vehicles equipped with RunFlat tires use the Tire Pressure Monitoring System (TPMS). It will help the driver to notice a puncture and deflation of the tire.

Can RunFlat tires and related systems be fitted to any vehicle?

Technically, Run Flat tires can be installed on any vehicle. However, we recommend installing them only on vehicles that require Run Flat tires. In addition, we highly recommend using the TPMS Tire Monitoring System with them.

Where can I install run flat tires on my car?

RunFlat tires can be installed at many specialized tire shops. Resetting the air pressure (resetting) in monitoring systems should be done in car repair shops.

Can run flat tires be patched if they have been flat?

If the RunFlat tire has been driven for at least a short time after a deflation, we recommend that you replace such a tire with a new one. In the event that a normal small puncture mark is found on the surface of the tire and the tire is not flat, it can be repaired using the usual technology for tubeless tires. The most optimal solution is to replace the tire, since its strength deteriorates after the patch is applied. If a puncture is seen in the shoulder area or on the sidewall, the tire cannot be repaired.

Tires with speed indices V/W/Y are generally not recommended for repair.

How long can I safely drive on RunFlat tires after they puncture and deflate?

On Nokian RunFlat tires, you can drive without pressure with a full load of the car for 50 km and with one driver for about 150 km. The maximum speed is 80 km/h, on slippery roads (on ice, snow) the maximum recommended speed is 50 km/h.

RunFlat tires are heavier than other tires. Does their use affect fuel consumption?

Although RunFlat tires are slightly heavier than regular tires, they do not require a spare tire to be carried, which affects the overall weight of the vehicle, so the impact on vehicle behavior or fuel consumption is very small.

Tire side cuts are not dangerous

Driving safety depends directly on the condition of the car wheels. Maneuverability, driving stability and comfort are associated with it. This element, which is in direct contact with the road surface, must be in perfect condition. Even minor damage and changes in pressure inside the chambers lead to serious imbalances, maneuverability and stability. This determines the importance of checking the condition of tires and their timely repair in case of damage. If a puncture is a fairly simple problem that a beginner with some skills and a special repair kit can handle, then a side cut is a much more serious problem.

The actual question is, how long can you drive on a flat tire?

With certain tire damages (microcracks, punctures, cuts, tread abrasion), the pressure inside the wheel decreases in different ways.

In the event of a puncture, there is often little time to get to the nearest car service, although it is preferable to call a mobile tire fitting team. 24-hour workshops are engaged in the rapid elimination of any problems on the road. It should be remembered that prolonged driving on a flat tire is a factor that reduces comfort and causes danger. This is especially true in turns, when the maneuverability of the vehicle is sharply reduced. Another problem that running on a flat tire will cause is the deformation of the disc and itself.

With a side cut, the danger increases even more. Such mechanical damage, in contrast to a puncture, leads to a break in the cord threads. Because of this, structural strength is lost. The best repairs will not restore its strength and integrity. Therefore, any tire repair can be taken as a temporary measure. The best solution is a replacement. This is especially true for high speed driving. With increasing load, any collision with a small obstacle, such as a curb, or a wheel falling into a hole, can cause a break.

Cut damage types

The following categories of damage are distinguished:

  1. Along the threads. Relatively easy option, recoverable.
  2. Across the cord. Dealing with such damage is complicated.
  3. Combined forms of injury. The cut affects both transverse and longitudinal threads. Such damage cannot be repaired.

Flat tire.

What to do?

In case of any damage, it is necessary to stop immediately in order to properly assess the situation. Any damage to the tire is felt instantly due to the sudden release of pressure and the ensuing loss of maneuverability. Often the car immediately begins to skid onto the side of the road or the oncoming lane. In this case, it is important to immediately level off the traffic and stop in a safe place, away from the road, but on a smooth and firm surface, where you can lift the machine to change the wheel. Stopping, you need to make sure that the car is not rolling. To do this, stop it with the engine off and raise the handbrake. It is also important to turn on emergency lights and put up a warning triangle if the stop occurred directly on the roadway. According to the regulations, it must be installed 100 meters behind the vehicle on an expressway or highway and 50 meters on a road outside the settlement. In a densely built-up area, the sign is placed directly behind or on the vehicle. In addition, a reflective vest should be worn.

After that, you need to do the following:

  1. remove the jack and spare wheel from the boot;
  2. jack up the car and remove the damaged wheel;
  3. move this wheel under the threshold of the car for greater safety;
  4. fix the spare wheel in the correct way, carefully checking for any slack;
  5. put the jack and the damaged wheel in the trunk.

Having decided to repair a puncture or cut yourself, you need to prepare tools and materials:

  • Alcohol to degrease the surface.
  • Raw rubber.
  • Building hair dryer or iron.
  • Sandpaper.
  • Rubber patch (preferably reinforced to compensate for damaged cords).

Having prepared the necessary, you can begin to repair. It consists of the following actions:

  1. Remove the wheel and place it on a level surface.
  2. Sand the damaged area with sandpaper.
