What Size Air Compressor for Truck Tires?

Air compressors have a wide range of applications such as inflating tires, powering other tools, etc., making them versatile tools. However, when it comes to inflating truck tires, you need to choose the right size air compressor to ensure that you can inflate your tires quickly and efficiently.

In this article, we will discuss what size air compressor you need for truck tires along with some important factors to consider when making your selection. So, without any further ado let's take a look at it.

Factors to Consider When Choosing an Air Compressor for Truck Tires:

Tire Size and Inflation Pressure:

The first factor to consider when selecting an air compressor for truck tires is the size of your tires and the required inflation pressure. Truck tires are typically much larger than car tires and they require a higher inflation pressure.

The recommended inflation pressure for truck tires can usually be found in the owner's manual or on the tire sidewall. So it is important to choose an air compressor that can provide enough pressure to inflate your truck tires to the required level.

Air Compressor Capacity:

The capacity of an air compressor is measured in gallons and refers to the amount of air that the compressor can hold in its tank. The larger the tank, the more air the compressor can hold and the longer it can run without needing to refill.

For inflating truck tires, a compressor with a tank capacity of at least 20 gallons is recommended.

CFM Rating:

CFM stands for cubic feet per minute, which is a measure of the volume of air that the compressor can deliver. The CFM rating of an air compressor is an important factor to consider when inflating truck tires because larger tires require more air to be inflated quickly.

A compressor with a higher CFM rating can deliver air more quickly and efficiently, which can save you time and effort.

Duty Cycle:

The duty cycle of an air compressor refers to the amount of time that it can run continuously without overheating or needing a break. For inflating truck tires, a compressor with a duty cycle of at least 50% is a nice choice.

A compressor with a higher duty cycle can run continuously without needing to stop, making it more suitable for frequent use.

Power Source:

Air compressors can be powered by electricity, gas, or diesel. If you need to use the compressor in remote locations or for extended periods of time, a gas or diesel-powered compressor may be more suitable. However, electric compressors are generally easier to use and require less maintenance.

Hose Length:

The length of the air hose that comes with your compressor is also an important factor to consider when inflating truck tires. If you have to inflate tires that are far away from the compressor, you may need to purchase a longer hose. But using a longer hose, you will face a drop in pressure compared to a short hose.


Finally, it is important to consider the accessories that come with your air compressor. Some compressors come with additional attachments such as a tire chuck or inflator nozzle, which can make inflating truck tires easier as well as more convenient.

Choosing the Right Size Air Compressor for Your Truck Tires:

Based on the factors discussed above, the ideal size air compressor for inflating truck tires would have a tank capacity of at least 20 gallons with a CFM rating of at least 10 CFM. The PSI can range from 40 up to 135 depending on your tire requirements.

However, it is important to keep in mind that the size of the air compressor you need will ultimately depend on the specific size and inflation requirements of your truck tires.

If you have larger truck tires or need to inflate multiple tires at once, you may need a larger air compressor with a higher CFM rating.

Conversely, if you only need to inflate one or two tires at a time, a smaller compressor may be sufficient.

It is also important to note that different types of trucks may have different tire sizes and inflation requirements. For example, a heavy-duty truck may require a larger tank and a higher inflation pressure than a lighter truck.

Make sure to check the owner's manual or tire sidewall for the recommended tire size and inflation pressure for your specific truck.

Frequently Asked Questions (FAQ):

Can I use a regular air compressor for truck tires?

It is possible to use a regular air compressor for inflating truck tires, but it may not be optimal as regular compressors typically have a lower CFM rating and lower maximum PSI than those designed specifically for inflating truck tires.

This means that it may take longer to fill a truck tire using a regular compressor, and it may not be able to inflate the tire to the desired pressure.

What is the maximum PSI for truck tires?

The maximum PSI for truck tires varies depending on the size and type of tire. Generally, light truck tires have a maximum PSI of around 30-80 PSI, while heavy-duty truck tires can have a maximum PSI of up to 120 PSI or more.

How often should I check the air pressure in my truck tires?

It is recommended to check the air pressure in your truck tires at least once a month or before any long drives. This helps to ensure that the tires are inflated to the correct pressure, which can improve fuel efficiency, tire wear, and overall safety.

What air pressure should truck tires be?

The air pressure for truck tires depends on several factors, such as the weight of the truck, the load it's carrying, and the manufacturer's recommendations. It's important to consult the owner's manual or the tire manufacturer's guidelines to determine the appropriate air pressure for your specific truck and tires.


Choosing the right size compressor for truck tires requires careful consideration of several factors, including tire size, inflation pressure, tank capacity, CFM rating, duty cycle, power source, hose length, and accessories.

By selecting an air compressor that meets your specific needs, you can ensure that you can inflate your truck tires quickly and efficiently without wasting time or effort. If you found this guide helpful, then share it and have a great day.
