How to Inflate Dual RV Tires?

RVs provide you the opportunity to go wherever you desire and are packed with features and facilities that give you the environment of a second home. However, having an RV entails a considerable number of duties for you as well. One of them is ensuring that the tires are always suitably filled with air.

Have you ever inflated RV tires? Multiple people have thought about this matter however, the solution is more complex than simply adding air. It’s particularly vital if your RV has dual tires. The ideal method for inflating the dual tires will depend on how familiar and assured you are when doing it.

We’ll demonstrate how to correctly inflate dual RV tires in this blog. Additionally, we’ll go over the significance of tire pressure and the steps to manage it.

With that said, if you’re willing to begin learning, let’s start!

How Do Dual RV Tires Work?

Some people might be interested in the tires’ actual structure and working. These are generally employed for non-steering axles. They also work well for heavy-duty fleets. The fleet’s durability can be doubled and kept stable with the addition of dual tires on each side of an axle. In the case of a flat, you can still drive, since the other 3 tires of the axle will cover the damage to that one tire.

Dual tires are fitted on every wheel of an RV. Oversized RVs like Category A or Category C motorhomes frequently use them. Multiple advantages of dual tires include enhanced strength and control. Likewise, they assist in more effectively dispersing weight, which boosts the lifespan of your tires. Dual tires, also necessitate additional air versus solo tires. It’s essential to frequently monitor the level and add air as necessary.

When Do You Require to Inspect the Dual RV Tire Pressure?

You must need to inspect:

  • Prior to starting the day’s drive.
  • As soon as you refuel it, perform a visual inspection, a thump test, or a laser temperature gun inspection.
  • Every month while it is in the store.

How to Estimate the Inflation Pressure in a Dual Tire?

A regular check of the pressure is vital because even a slight reduction in pressure can affect how the RV performs. There are several methods you may use in estimating inflation pressure.

  • Operating a tire pressure gauge seems to be the simplest method. The majority of car equipment retailers sell these compact, portable gadgets. The gauge only needs to be inserted into the valve stem to get a reading of the present level.
  • Digital tire pressure gauge usage is an additional method of checking inflation levels. It operates similarly to a typical tire pressure gauge, however, it’s more precise. In addition, it is simpler to understand, which is beneficial when you’re not familiar with dealing with a standard gauge.
  • We can also visually inspect the tires when we don’t really have availability for the tire pressure gauge. Although this method isn’t as precise as utilizing a gauge, however, you will get a basic notion of whether the tires are adequately pressurized with this method.

How to Inflate?

Step-by-Step Procedure!
It’s important to do it correctly, so follow the steps given below:
Air Compressor
It is important to operate an air compressor with such a high adequate PSI capacity. Normally, dual RV tires should be inflated to a maximum of 120 PSI. Not every air compressor, though, have that capacity. Ensure your air compressor can produce at least 120 PSI if you want to utilize it.
Pressure Gauge
When you’re operating the air compressor, you will require a pressure gauge that is adequate for reaching the valve stem. You can watch the tire’s PSI with the assistance of the pressure gauge to prevent it from under or over PSI.
Outside Tire
Now it’s time to inflate RV outside tires. Take off the stem lid, connect the air hose and air chuck to the valves, and fill it with air. During inflating, don’t forget to examine the PSI levels. Attach the stem lid after that.
Inner Wheel
After that access the valve stem. It’s necessary to get because it is used to fill dual tires. Angled chuck use makes it easier to get the valve stem. These chucks are available in various sizes. To identify which is good for you, you might be needed to test some chucks. As an option, you might think about purchasing a valve stem attachment with several angles.
Chuck and Valve Stem
Before operating an air compressor, first, connect the chuck to the valve stem.
Inflate inner Tire
After that, minimize the lever of the compressor and inflate the air in the inner tire. Examine the inner tire’s present PSI rating after releasing the lever. Continue repeating the process till the needed pressure is reached. Move gently and gradually as you should not exceed the planned rating when trying to obtain it. Tires that are under-inflated will be heated up and increase the chance of a collision. The lifecycle of overinflated tires will be reduced, and the riding will be harsher. Early tire problems can result from either scenario.
Stem Lid
To avoid the lid shattering while replacing, carefully tighten the lid.

What Risks Do Overinflated Tires Pose?

Although it may look not like a big concern, it can be quite harmful.

  • It may lead to bursting the tire which results in death or injuries.
  • It minimizes the traction which makes it challenging to handle the RV.
  • These tires use more fuel which might be expensive for you.
  • Minimizes RV’s efficiency.

What are the Advantages of Tire Pressure Monitoring Systems (TPMS)?

Using a TPMS is an excellent approach for monitoring tire inflammation pressure. Here are some advantages of this system:

  • A flat tire is the most alarming situation that might occur while you are driving your RV. You’ll be aware right away if one of your tires is losing air thanks to a TPMS. So, you will have enough duration to fill the air as a result.
  • In addition to being inconvenient, flat tires can be costly to repair. So, the system saves your money by avoiding.
  • It also helps to prolong the lifespan of tires. Overinflated tires are less durable than properly inflation tires. An incredible method to extend the life of tires is using a TPMS.
  • They provide comfort. You will not be concerned about the tires going flat while driving because you’ll understand they are adequately filled.

Final Words

Dual RV tires require different inflation techniques than standard tires. It seems to be more difficult. Fortunately, you have numerous methods to add air to them. Many of them are simpler, so whether you pick the simpler one or the more difficult one is completely based on your preference.

It’s easy to fill up the tires of your RV, and you may do it at home or at a gas store. However, it’s vital to watch out for the overinflation of your tires. It might be risky for tires to explode if they are over-inflated. Before getting onto the roads, ensure your tires are inflated.

Knowing that you are aware of the steps and reasons to properly air dual RV tires, you should feel more at ease when getting ready again for a vacation. Simply, keep in mind to use a compressor with a suitable PSI, select the valve stem extender carefully, then don’t be scared in removing the tire for placing the inside valve stem correctly.

Now, you probably get the idea here, so go out to start enjoying your journey!


Air quality in camper vans ranges from 40 to 65 PSI. Applying this kind of pressure is improper. This is how the median figures show up. It represents how the majority of tires are inflated with PSIs of this level. You need to do it according to your RV.

Either one or both gauges might be off if you see a large variation between values (3 PSI and more). When they can measure within a range of one to two PSI, then they would be reliable.

RV tires must be filled to their maximum pressure while they are cool. The Specified highest speed of such tires must not exceed 65 mph. You shouldn't go more than 65 mph.

While putting air in your tires, you could run into some difficulties. Reaching the valve stem becomes the most frequent issue. It cannot be challenging to get to the stem if your dual rims are correctly positioned.

Yes, it's feasible and easy to do at the gas station. You just need to follow the guide to get the required results.
