How to put air on a car tire


How to Properly Inflate Your Car Tires

Your car's tires play many valuable roles in the safety and function of your vehicle — from helping you navigate twists, turns, and stops like a pro to carrying the full weight of your car. That's why it's important to pay special attention to these essential components.

Fortunately, maintaining the proper tire pressure on your vehicle is one of the easiest yet most effective ways to care for your car tires. Learn how to check air pressure and inflate your tires with this helpful guide.

Why is Tire Pressure Important

Underinflated tires can not only reduce fuel efficiency, but it can also run the risk of getting into an accident, losing proper steering control, damaging various components of your vehicle, and more. If you notice that your tire's air pressure levels have dropped, it's best to prioritize inflating them as soon as possible.

How to Check Tire Pressure

Checking your vehicle's tire pressure is a relatively simple task. You'll want to start by purchasing a tire gauge. These vary in price depending on the type you choose (i.e., digital, basic, etc.) but can usually be found for well under $40. It's also essential to keep a tire gauge on hand, as some gas station air hose gauges are not always accurate. Many modern cars and trucks also display the tire pressure for each tire on the dashboard. Once you have your tire gauge in hand, it's time to determine the proper pressure for your vehicle. 

    Find the correct inflation level. To do this, you can either look for the recommended pressure on the sticker within your driver's-side door jamb or consult your car owner’s manual. This is the tire pressure specification when the tires are cold, meaning not driven for a few hours.

    Remove the valve stem cap from your tire. Some cars and trucks have green valve stem caps with an “N” on them - this means the tire is filled with nitrogen instead of air (air is mostly nitrogen). If your tires have these green valve stem caps, you can find some special stations that dispense nitrogen, but be aware that you can use normal air as well. The inflation pressure specifications are the same regardless if the tire is filled with air versus nitrogen. 

    Connect your air pressure gauge to the tire’s valve stem until you receive a reading.

    If the pressure level number seems unrealistic, remove the gauge and try again. This time, ensure that the indicator is connected firmly to the valve stem.

    It's not always possible to tell if a tire is underinflated by giving it a quick once over. So, check your PSI levels with a gauge each month and after extreme temperature changes. You'll also want to check your pressure levels when your tires have had time to cool down since air expands within your tires while driving.

    How to Inflate Car Tires at a Gas Station

    Filling your tires with air at a gas station is relatively simple. Bring your tire gauge and some spare change since some are coin-operated and are not always accurate in their pressure readings. Try to make this the first stop if you are running errands so that your tires are still relatively cool from sitting for a few hours. Then, follow these steps:

    1. Park your vehicle close to the air dispenser so that you can comfortably reach each of your tires with the hose.
    2. Remove the valve stem caps from each tire.
    3. Use your tire gauge to check the air pressure in each tire.
    4. If the pressure is low, begin by adding air (one tire at a time) with the hose. 
    5. Stop periodically to ensure you haven't overinflated your tires. If you do overinflate, release some of the air slowly until you reach the proper amount.
    6. Replace tire valve caps once you've gotten them to the appropriate pressure levels.
    7. Enjoy the ride, and continue to monitor your tire pressure regularly.

    How to Inflate Car Tires at Home and On-the-Go

    1. Find a level surface under the shade.
    2. Remove the valve stem caps from each tire.
    3. Use your tire gauge to check the air pressure in each tire before starting. Remember that the tire temperature and air pressure will rise as you drive.
    4. If the air pressure is low and you have access to an air compressor at home, firmly press the air-hose onto your tire valve stem. You should start to hear air entering the tire. If not, confirm that the air hose and your tire’s valve stem are both securely connected.
    5. Try not to overinflate your tires. If you do, slowly release some of the air until you reach the correct amount of air.
    6. Replace the caps.

    While our tire technicians are happy to check your tire pressure for you any time, it’s also something you can do yourself. To prevent over- or under-inflation and the possible tire failure that comes with them, follow these steps:

    1. THE RIGHT AIR PRESSURE: Your vehicle's manufacturer specifies the "right amount" of air for your tires; look for it on the door edge, door jamb, glove box door, or fuel door. It is also mentioned in the owner's manual of your vehicle.
    2. TIRES SHOULD BE COOL: Even if you’ve only driven a short distance, your tires will get hot. Always allow your tires to cool down before checking their air pressure. (NOTE: If you must drive a distance to get air, check and record the tire pressure first and add the appropriate air pressure when you get to the pump. It is normal for tires to heat up and the air pressure inside to go up as you drive. Never “bleed” or reduce air pressure when tires are hot.)
    3. UNSCREW THE CAP: Locate the low-pressure tire and turn the valve cap to the left.
    4. CONNECT THE TIRE GAUGE: Press a tire gauge firmly against the valve.
    5. START THE AIRFLOW: To reach the recommended air pressure, add air.
    6. DON'T OVERFILL THE TIRE: If you happen to overfill the tire and need to release air, use your fingernail or the tip of a pen to press on the metal stem at the center of the valve. Then, using your tire gauge, recheck the pressure.
    7. SCREW THE VALVE CAP BACK ON: Replace the valve cap by tightening it to the right.
    8. ADD AIR TO EACH TIRE: Proceed to fill the rest of the tires, including the spare. (NOTE: Some spare tires require higher inflation pressure.)
    9. INSPECT THE TIRES: Visually inspect the tires to ensure that there are no nails or other objects lodged that could poke a hole in the tire and cause an air leak.
    10. INSPECT THE TIRE SIDEWALLS: Check the tire sidewalls for any gouges, cuts, bulges, or other anomalies.

    NOTE: Air pressure in a tire goes up (in warm weather) or down (in cold weather) 1–2 pounds for every 10 degrees of ambient air temperature change.

    The optimum air pressure for each tire on your vehicle is determined by the engineers who assisted in the design and production of your car. Proper tire pressure and inflation aid in optimizing the tire's and vehicle's driving performance, grip on the road while driving, and overall ride quality. Maintaining your vehicle’s tire pressure to the recommended pressure is critical to your vehicle’s ability to stop, start, and turn corners.

    There are a few different places listed below to find your recommended proper tire pressure around your vehicle.

    • Vehicle’s Owner’s Manual
    • Driver’s Side Door Jamb Placard
    • Glove Box Placard
    • Gas Tank Placard

    How to properly inflate a car tire / What to consider?

    Summer tires in Krasnodar at wholesale prices in stock and on order.

    Car tire is responsible for driving safety and comfort. It needs to be kept in working order. This is a prerequisite for long and safe operation. Not all drivers know how to pump up a wheel, we will analyze the nuances of this work in more detail.

    Why is it important to keep the tire pressure correct

    Tire pressure is an important parameter, it is he who is responsible for the main technical characteristics of the wheel. The car manufacturer calculates this parameter in advance and indicates it in the recommendations.

    If a tire is underinflated, this will lead to increased fuel consumption in the first place. This is due to a decrease in the rolling coefficient. Uneven grip with the road surface also occurs, leading to a decrease in traffic safety, this is felt in the form of more difficult driving. Tire wear increases, with a strong drop in pressure, the rim of the disc can cut the sidewall.

    It is also not worth pumping tires. The tire will wear unevenly, the middle part of the tread will suffer. Increased pressure can provoke an explosion and complete destruction of the tire on the road. In addition, the stiffness of the wheel will increase, and the braking efficiency will decrease.

    How often to check tire pressure

    Pressure checks must be carried out at least once a month. If there are sudden changes in temperature outside, it is necessary to check the parameter every two weeks. Be sure to check the pressure before every long trip.

    Visually inspect tires in the morning. If there are doubts about the quality of the pump, it is worth checking the pressure, if necessary, pump up the tire. Checking and pumping should be carried out on all wheels, different tire pressures can lead to loss of vehicle controllability.

    Be sure to check the condition of the spare wheel.

    Where to find the correct tire pressure for your vehicle

    Tire pressure is determined by the car manufacturer, he finds out through tests to what extent the rubber can be inflated. The data must be indicated in the documents for the vehicle.

    For greater simplicity, additionally indicate the parameters on the plate. It can be found on the A-pillar of the car or on the inside of the gas filler flap. In rare cases, a plate with the main technical parameters may be on the door. It remains to find a plate on your car and see to what pressure to pump tires.

    When you can pump the wheels

    There are certain pumping rules. They include not only data on how much air to pump into the tire, but also when to do it. The main requirement is to inflate the tire only after a long parking. The tire heats up while driving. According to physical laws, temperature directly affects gas pressure. Accordingly, immediately after the stop, the indicator will not be accurate.

    It is necessary to wait until the temperature of the air in the tire is equal to the outside. It takes 3-4 hours for this. After waiting so long, you can accurately measure the pressure. It is most convenient to do pressure measurement and pumping in the morning, after overnight parking.

    How to inflate a tire with your own hands

    Inflating a car tire is not difficult, but a beginner may have a few questions. We will analyze the stages of the process, in the end you will know how to properly pump up the wheel. To work, you will need a pump, you can use a foot or compressor. Now there are compressors that run on the cigarette lighter. If the pump does not have a pressure gauge, this device will also be needed.

    Let's walk through how to inflate a tubeless tire step by step.

    • We put the car on the handbrake. It is advisable to choose a flat place.
    • We take out the pump and pressure gauge. If the compressor is electric, we connect it to the power supply. Usually the connection is made through the cigarette lighter, just insert the tip of the cord into the cigarette lighter.
    • Unscrew the protective cap from the nipple of the tire. The cap must be placed carefully to the side so as not to lose.
    • Connect the hose tip to the wheel. To do this, the tip is simply put on the nipple, at the beginning you will hear the sound of escaping air. This is fine. Insert the tip completely.
    • After the handle of the handpiece is turned at an angle of 90°. So we fix the hose on the nipple.
    • Look at the manometer. It shows the pressure in the tire, if it is not enough, turn on the compressor. We are waiting for the pressure gauge to show a normal parameter.
    • Detach the tip. This must be done carefully, but quickly enough.
    • Screw on the previously removed cap.

    Further, all the described procedures are repeated on the remaining wheels, including the spare. Now the car is ready to drive.

    If the pump is foot operated, all steps are the same, except for the power connection. The air supply is carried out by setting the pump piston in motion, this is done by foot.

    Inflating a car tire is a simple job. This can be done by every car owner, even with no experience at all. The main thing is to know the basic rules, they are simple, it will not be difficult to fulfill them. But save time on a trip to a car service.

    How to inflate a car tire?

    This question, of course, is relevant only for beginners, both in driving and in the automotive business in general. An experienced driver in response to the question “How to pump up a tire” will grin and answer:
    - How, how. Take it and pump it up.
    Since this question does not represent any difficulty or mystery for an experienced driver.

    So the car has wheels. Wheels have tires. These tires need to be inflated from time to time. To do this, you need to know what the optimal pressure should be in the tires. Keep in mind that the front tire pressure may be slightly different from the rear tire pressure. However, an indicator of the proper level of tire pressure is available in the passport. Get into the habit of at least visually inspecting the wheels before each exit from the parking lot or garage - have they been let down? And if it even seemed to you that one wheel was “squeezed” more than the others, do not be too lazy to check its air pressure level. This means that you must have a pressure gauge in the glove compartment. And if the pressure is less than it should be, the wheel should be pumped up. Experienced drivers - and you probably noticed this - kick before leaving

    wheels. And by impact they can determine whether it is worth pumping up the wheel or not. As for you, if you took the pressure gauge in your hands, check, just in case, the pressure in all wheels. Reduced pressure in tires while driving will create uneven adhesion to the road surface and contribute to tread wear. Uneven distribution of the load, which necessarily happens with a difference in tire pressure, will lead to a violation of the stability of the car while driving. You will feel it by the fact that the steering wheel will begin to “lead”. In this case, you should stop and pump up the wheel. In addition, insufficiently inflated tires lead to the fact that the engine begins to "eat" gasoline. Do you need it? Therefore, you should get into another habit: to carry a compressor or at least a pump in the trunk of your car along with another tool. In particular, to replace the wheel in the event of a tire puncture. Because today's habit of not having any tool in the trunk at all is a bad habit.

    It is better to pump the wheels with a compressor. They appeared in wide sale at the very beginning of the 90s of the last century, but failed after two or three pumpings. Now the quality of compressors has improved somewhat. In fact, each compressor has a built-in pressure gauge, so you can safely control the level of pressure in the wheel. What steps do you need to take to pump up the wheel with a compressor? Unscrew the cap from the tire valve. Put the nozzle of the compressor hose on the valve and see what the pressure is in the tire. If it is below the norm - and you learned it by heart - then you should definitely pump it up. Next, you connect the compressor to the cigarette lighter socket (after removing the cigarette lighter itself) and turn on the compressor. After the pressure gauge has shown the norm, you turn off the compressor and disconnect the hose from the tire valve. Experienced drivers then spit on their fingers and smear the surface of the valve with saliva. If the saliva begins to bubble, then the nipple is bleeding air. In order to stop this process, you take the valve cap and its reverse side, which has a pin with a groove, twist the nipple. When the bubbling of saliva stops - which means that the bleeding of air has stopped - you screw the cap on the tire valve and you can continue to move.
