What Size Air Compressor Do I Need To Inflate RV Tires?

Inflating RV tires is an essential part of maintaining your recreational vehicle's safety and performance. However, selecting the right size air compressor for this task can be a bit tricky especially if you're new to Rving.

In this article, I will discuss everything you need to know about choosing the right size air compressor for inflating your RV tires so without any further ado let's take a look at it.

Why Is The Correct Tire Pressure Important For RVs?

Maintaining the correct tire pressure is essential for any vehicle but it's even more critical for RVs. RVs are large and heavy vehicles that require a lot of power to move so keeping the tires properly inflated is crucial for maintaining fuel efficiency and stability on the road.

Overinflated or underinflated tires are more prone to blowouts which can lead to dangerous accidents.

What Pressure Should I Inflate My RV Tires To?

The recommended tire pressure for your RV will depend on the manufacturer's specifications and the weight of your RV.

You can typically find the recommended tire pressure in your RV owner's manual or on a sticker located inside the driver's side door. It's essential to follow these guidelines as closely as possible to ensure your RV is safe as well as performs well on the road.

What Size Air Compressor Do I Need To Inflate RV Tires?

The size of the air compressor you need will depend on the size of your RV tires and the amount of time you're willing to spend inflating them. In general, RV tires require a lot of air to inflate them properly, so you'll need a compressor with a specific CFM (cubic feet per minute) rating.

To determine the appropriate size of air compressor for your RV you'll need to consider three main factors: the volume of air the compressor can deliver and the pressure it can achieve and its tank size.

Volume Of Air:

The volume of air a compressor can deliver is measured in CFM and it's essential to choose a compressor that can deliver enough air to fill your RV tires.

Typically, you'll need a compressor that can deliver at least 2-4 CFM to inflate RV tires quickly as well as efficiently and it can go higher depending on your tire requirements.


The pressure a compressor can achieve is measured in PSI (pounds per square inch). Most RV tires require a pressure between 80 and 120 PSI so you'll need a compressor that can achieve this pressure.

Tank Size:

When it comes to inflating RV tires, the tank size of an air compressor is an important factor to consider. The tank size determines how much compressed air the compressor can store which affects the amount of time it takes to inflate the tires.

For inflating RV tires, it is recommended to use an air compressor with a tank size of at least 3-6 gallons and this is because RV tires require a significant amount of air pressure and this tank size will allow the compressor to maintain a steady airflow without constantly cycling on and off.

A larger tank size also means that the compressor can handle multiple tires without needing to stop and refill the tank which can save time and effort.

However, it's important to note that a larger tank size also means a big and heavier compressor which may not be practical for those who need to transport it frequently.

Factors To Consider When Choosing An Air Compressor:

In addition to the volume of air and pressure there are a few other factors to consider when choosing an air compressor for your RV:


If you plan on taking your RV on the road you'll want a compressor that's portable and easy to transport. Look for a compressor that is portable or it may come with wheels or handle for easy maneuverability.

Noise Level:

Air compressors can be quite loud so consider the noise level when choosing a compressor so look for a compressor with a low decibel rating if noise is a concern for you.

Power Source:

The power source for an air compressor that can inflate RV tires depends on the type of compressor you have as small portable air compressors may run on 12-volt DC power which can be supplied by your RV's battery. It's important to ensure that your power source can provide enough power to run the compressor as well as inflate your RV tires to the required pressure.

Duty Cycle:

The duty cycle of your air compressor is also important as the duty cycle refers to the amount of time your air compressor can run continuously before it needs to shut off to cool down. If you have larger rv tires you may need an air compressor with a longer duty cycle to ensure that it can inflate your tires without overheating.

Frequently Asked Questions (FAQ):

Can I Use A Regular Air Compressor To Inflate My RV Tires?

It is possible to use a regular air compressor to inflate your RV tires but it may not be powerful enough to provide the necessary PSI and CFM. Using a regular air compressor could also take longer to inflate your tires which can be inconvenient.

How Often Should I Check My RV Tire Pressure?

It is recommended that you check your RV tire pressure before each trip and at least once a month during the season. It is important to keep your RV tires properly inflated to ensure your safety while driving.

What Is The Recommended Tire Pressure For My RV Tires?

The recommended tire pressure for your RV tires can vary depending on the type of tire and the weight of your RV. You can find the recommended tire pressure in your RV owner’s manual or on the tire itself.

Is it Necessary To Inflate My RV Tires To The Maximum PSI Listed On The Tire?

No, it's not necessary to inflate your RV tires to the maximum PSI listed on the tire. Instead, you should follow the manufacturer's recommendations for the appropriate tire pressure based on the weight and specifications of your RV.

Can I Use A Tire Inflator Or Air Pump Designed For Car Tires To Inflate My RV Tires?

While it's possible to use a tire inflator or air pump designed for car tires to inflate your RV tires it's not recommended as these inflators may have a low CFM rating and may not be able to inflate the larger and heavier RV tires efficiently. It's best to use a compressor with a certain CFM/PSI rating specifically designed for inflating RV tires.


Choosing the right size air compressor for RV tires is essential for maintaining your RV's safety and performance. You'll need a compressor with a specific CFM rating along with a proper tank size and the ability to achieve the necessary pressure.

Other factors to consider include portability, noise level, power source, and duty cycle. By selecting the right compressor you can ensure your tires stay properly inflated and your RV performs well on the road. If you find this guide helpful then share it and have an amazing day.
