What Size Air Compressor For Truck Tires You Need


what size air compressor for truck tires

Do you need to know about what size air compressor for truck tires you should use? Read this now, and you will get your right answer.

An air compressor is a mechanical device that transforms potential energy from the compression of air pressure. We need an air compressor for different purposes. We may need it for airbag lowering kit, vehicle painting, inflating tires, and so on.

But all the size of the air compressor is not perfect for all types of work. There are some definite size and considering matters that one must know before using the compressor in their vehicle.

Here, we provide the elaborated information that can help you to select the right size. So, keep reading.

Standard Air Compressor Sizes For Truck Tires

You must prior to some considerations while knowing what size air compressor for truck tires will be perfect. They are

  • The PSI
  • The CFM
  • Number of gallons
  • Inflation speed

By keeping these things in mind, you have to measure the right size. It’s not that much hard. Just read it sincerely, and you will know by yourself quickly.

The PSI

PSI (Pounds per Square Inch) refers to the measure of the pressure that needed relative to each square inch of area. Here the pressure is measured in pounds.

As the air compressor will compress air from high pressure, this measurement of PSI will decide how much force it will provide and, consequently, how much energy converted into the compressor.

Most of the typical truck tires need, on average, 40 to 50 amount of PSI. The large truck tires need 50 to 70, and for high-duty truck tires, you need 80 or more than that. But if your tire has some recommendations, then you should go with that choice.

The CFM

CFM (Cubic Feet per Minute) means the measurement of volume in cubic feet unit applied in each minute. The rate of the volume per minute is the CFM number.

The CFM number is directly interrelated to the PSI number. It depends on how much pressure is applied, and then the volume is gained for desiring HP(Horse Power).

The CFM number also follows the famous Boyl’s law in Physics. The law is

Here,

P1 = The pressure that was applied at the beginning that is the tire

P2 = The stress you get or the resulting pressure in the tank

V1 = The applied volume in the tire

V2 = The consequent volume in the tank

So, In the above formula, by putting the value of P1, P2, and V2, you can easily know the amount of  V1 you need to apply that is the CFM measure.

Still, if you want a suggestion, then we can say if your PSI is 90, then the CFM will be 15, and if your tire PSI is 100 or more than 100, then the CFM can be ten or less.

The more PSI, the less CFM results in quick compression.

Number of Galon

You can think of the number of gallons from the air tank. In the air tank, the bigger the tank size, the number of gallons.  The tank size does not matter most. It is mainly for the fast working procedure and less compression time.

Again the more massive the tank size, the more expensive it is going to be. On average, it can be said that a tank of 20 gallons can result in 90 PSI pressure. But mostly 80 gallons are the professional’s choice. More than that is also preferable. But less than that sometimes can’t even fill at least four tires.

Inflation Speed

While sizing the air compressor, you must not forget about the inflation speed for the tires. Tire inflation much depends on the given PSI and the loads on the tires. The more PSI means more tire inflating.

So, be aware of the inflation power and speed of the tires and, according to that, provide the pressure.

These are the considerations for choosing the right size of air compression. The air compressor does not work alone it works in harmony with the parts mentioned above.

Don’t Forget the Gauge

But don’t forget to have a pressure gauge to check reading. It’s a very crucial one to have. Whether your applied pressure is right measured or not, whether you have over-pressurized your tires or not, etc.- keep them under your observation always.

If your air compressor company does not provide a gauge, then have a dashboard for monitoring. Most of the companies offer a panel single or dual.

Final Words

Air compressor works concerning different facts. So, to know what size air compressor for truck tires, you should have explicit knowledge about the size of the parts.

In this article, we have cleared out all the measurements for truck tires compressor size.

Read it and be sure of the air compressor size-related matters.
