How to Use an Air Compressor to Fill a Tire

There are several ways to inflate your car’s tire by yourself or with the help of your mechanic. In the absence of your mechanic, knowing how to inflate your car’s tire is convenient in emergencies where your car gets a flat tire. The following tips could come in handy in case you get a flat tire and are on short notice or planning a long drive or road trip:

Always Check Your Tire’s Pressure

Before leaving the house for work, vacation, or just driving around the neighborhood, it is essential to check that your cars’ tires have just the right amount of pressure. The tire pressure of one vehicle differs from another, and you should therefore pay attention when checking the pressure. However, it is nothing to worry about since you can get your car’s pressure information in the car manual

The average pressure for car tires ranges from 32 to 35 per square inch, while the pressure for a large truck is around 100 per square inch. Besides the tire’s pressure, you can check its temperature since it is best to inflate a tire when it is cold.

A hot tire might indicate higher tire pressure due to air expansion, and a cold tire will give a more accurate reading. A tire gauge is convenient for checking tire pressure and predicting how much more pressure your tires need.

Prepare Your Equipment

Once you have checked the pressure of your car tires and determined that they are somehow inflated, get your equipment ready. Get ready by selecting a high-voltage power source, then plug in your air compressor that should have a voltage of about 12.

Checking the tire’s pressure helps you decide what type of air compressor to get for your car, and in most cases, a small air compressor will do the job for you. A small air compressor that keeps the pressure between 100 and 150 per square inch will be sufficient.

Attach an air hose onto the compressor before switching it on to start the motor and get the compressor ready to pump air into your tires. Positioning your equipment is also vital as you should place the air compressor near your car tires. At the same time, you should tightly connect it to the power source.

Inflate Your Tires

Before allowing the compressor to accumulate air, you must check to see if it is running on the correct circuit and voltage to avoid blowing the compressor.

For a smaller car, a two-prong plug can be used for the air compressor, which is usually of small volume two, and for a large truck, using a three-prong plug would be more convenient. A portable air compressor will most probably have tires, and this will help you quickly move your equipment around.

  • Activate the safety position on the nozzle, fasten the hosepipe to the valve system, and turn on the compressor. It would help if you fastened the quick coupler at the end since it aids the compressor to push air into the valve, which is usually small in size.
  • Carefully remove the stem cap on your tire before attaching your hose and safely store it in prominent areas like your pocket to help you quickly find it after you are done inflating your tires.
  • Please wait for your tires to inflate. The duration they take varies depending on their size and how flat they were when you started inflating them.
  • Observe the gauge on your air compressor to get guidance on how much air you need to inflate your tire. Some gauges automatically stop inflating your car tire once the required amount of air is attained. Using a digital inflator will save you the trouble of figuring out how much air your tires require since they give accurate readings.

You should stay vigilant when inflating your tires. This vigilance helps prevent the overinflation of your tires.

Detach the Air Compressor

Once you are satisfied that your tires are fully inflated with air and fit for the road, you may detach the hose from your tire. Before detaching the hose, push down on the tire gauge to release excess air if the tire happens to be overinflated.

Remove the hosepipe from the compressor. The hosepipe removal might be accompanied by a hissing sound that is perfectly normal and, therefore, no reason to be concerned.

Replace the tire’s stem cap on the tire after removing the hose. You can then detach the air compressor from the power source, give it a few minutes to cool before storing it safely for future use. Your car is then set to go for that road trip or that drive around the neighborhood with no flat-tire worries unless it becomes a puncture, then that is a whole other problem by itself.

We often perceive car service as a complex thing to perform. This perceived complexity may lead us to rely exclusively on our mechanics for even the tiniest car problems. Ironically, we usually find that we can solve the said problems with ease.

The suddenness of experiencing a flat tire at the most inconvenient time forces us to learn how we can solve this issue by ourselves. This article will help you inflate your flat tire next time it happens, and you cannot get hold of your mechanic. It will also save you some coins while at it!
