Buyers Guide on the Best Portable Tire Inflator for RV
Choosing the best portable tire inflator for your RV may not be an easy to do the task. You have to know what factors to consider and understand so as to make the right decision. We have done the research and come up with important points you need to check for when shopping.
- Type of Compressor
Generally, there are two types of compressors; portable and onboard. Portable inflators are the most commonly used by owners of RVs and trailers. Just as their name goes, they are easy to carry around and can compactly fit in your RV without taking much of your space.
They come with a hose and cord that allows you access to each tire of your RV without having to move the inflator from one point to another. If you are out looking for convenience, then this is a must have for you.
On the other hand, on board compressors are those found on the underneath of your RV. They are put there permanently and cannot move. However, they are usually hard to install and are not compatible with most RVs. This is why most people prefer portable inflators.
- PSI Rating
PSI in full is pounds per square inch. This is what measures air pressure. It determines how much pressure can fill an individual tire at a given time. Notably, your inflator should be able to output higher PSI than that, which is recommendable for your tires.
The PSI rating goes hand in hand with CFM, which measures the rate of airflow. At 0 PSI, air flow tends to be higher. Besides, the higher the rating of CFM, the faster your tires tend to fill.
A good air compressor should be able to serve many purposes apart from only inflating car tires. When shopping, check if the inflator you plan on buying has any other additional functions and does not limit you to car tires only.
It should inflate sports balls, bicycle and motorcycle tires, balloons, and recreational toys. Therefore, it should come with extra fittings to handle other equipment with different nozzles other than those of car tires.
- Length of Hose and Cord
This is among the vital factors to consider as it enhances performance. Having a compressor with a hose that has a pretty good size ensures that it can reach all the tires on your RV when pinned on one location.
You do not have to carry it around with you every time you need to inflate pressure on a tire. This improves the convenience of your inflator and makes it easy to operate.
Getting an inflator featuring a compact and lightweight design is the ideal deal for you. Are you able to carry it around comfortably without experiencing fatigue? Is it small enough to fit in your RV’s storage compartment? These are some of the questions you should ask yourself before making a decision.

How does Portable Tire Inflator work?
A portable tire inflator’s primary purpose is to maintain air pressure on your RV’s tires to prevent any damages to them. Such damages include flat or worn-out tires. It is vital to always check your tires' pressure while on the road or even if your RV is parked.
A tire inflator usually has a tank that contains air full to the brim. Most of these inflators get their power from a 12V motor. Nonetheless, some inflators are cordless. Your choice of inflator solely depends on your car tires’ inflator needs, provided there is maximum performance.
The inflator has two main parts that push air into the storage tank; piston and cylinder. To ensure there is the maximum pressure, the piston will continually force more air into the tank. This will cause the inflator to stop pumping air into your tires, thus ready to get back to the road.
The air from the tank transmits to the tires through an air hose. You should always consider a lengthy air hose if you want to achieve efficient results. Connect this air hose to your car’s battery, and air will fill your tank according to the set pressure.
To understand how the inflator works, it needs you to know the CFM and PSI rating. At 0 PSI, the CFM will be higher. A higher CFM rating indicates that the inflator is more powerful and will yield excellent results faster. PSI ratings ranging between 100-150 PSI are the best.
How do you pump a portable tire inflator?
1. Ensure that you have a 12 volts inflator when inflating your tire.
2. Next, plug your inflator’s 12 volts plug into the socket of your car.
3. Now you can connect the inflators air holes to the end of the tire that you intend to fill.
4. Note that some tires may require the use of screw-type connectors in connecting the air hole to the tire's valve while, on the other hand, others make use of a rock lever connector.
5. You can tap your inflator so that you can begin filling.
6. When your inflator gauge reaches the maximum recommended type for that tire, you can turn the inflator off and disconnect the air holes as well as the 12 volts plug.
7. Always use a pressure gauge to ensure that the inflator does an excellent job.
What is the easiest way to inflate RV tires?
Using a portable RV inflator makes inflation of your tires a hassle-free task. The first thing to do is to remove the valve cup utilizing a screw and then store it away safely as you will have to put it back eventually. This curbs against any air leak from the tire.
You then need to attach a pressure gauge on the valve so as to measure the level of pressure on your tires. Most inflators come with pressure gauges, which makes it convenient. In the case that there is none, you will need to buy a separate gauge.
The next step is to start filling the air in your tire according to its needs, such as the type of tire. If you are unsure about the whole process, you can always read a user manual that comes with the inflator or you can google for instructions just to be sure.
After filling in air pressure to your satisfaction, you can then return the valve cap to its initial position on your tire. This ensures no dust enters the valve of your tire, which may eventually cause damage. Your car tire is now ready to go back to the road.During inflating, make sure you take into consideration the weight of the load and the number of axles of your vehicle. These two factors mainly affect the amount of air pressure you feed into your tires. Remember, you are not supposed to over inflate or under inflate.
How to check RV tire pressure
It is essential to regularly check the pressure of your RV tires so as to keep them in check. Each vehicle, ranging from a regular car to SUV to RV, has its own different pressure needs. They can never be the same.
Usually, manufacturers recommend the standard tire pressure or your vehicle, whether new or used. This helps you know the amount of pressure to inflate into your tire. Besides, tire pressure is dependent on factors such as weight of the load, number of axles, and type of tire.
Always check the pressure before and after adding more air so as to avoid overfilling or under filling. One can tell if a tire has enough pressure or not by just looking at it. However, this may not give you accurate results, forcing you to use a tire pressure gauge.
Most portable tire inflators come with an in-built pressure gauge that enables you to monitor your tires' pressure. With this, you are sure to get accurate readings. Most of them have between 3 to 4 readings to enhance their performance.Thus, you can quickly tell when your car tires need to be inflated and when the desired pressure is reached with the right pressure gauge.
How much should I inflate my RV tires?
This is a confusing question that many vehicle owners fail to get the answer. Most assume that the right pressure to inflate into their car tires is the one that has been recommended by the tire manufacturers. If your tire rating is 60PSI, then inflation pressure should be 60 PSI too.
That is never the case as your tires may still not be stable enough. So you have to determine the right PSI or your tire to be on the safe side. Depending on the weight your RV carries, the PSI rating is indicated somewhere on the tires or owner’s manual.
You should use the PSI rating on the sidewalls of your RV, which show the maximum tire pressure. Mostly it is between 40-65 PSI. Ensure that you do not inflate your tires to surpass the given pressure. Also, it should not be less than whatever has been recommended.
The number of axles on your RV and the weight of load largely determine the amount of pressure it will need. There is always a label showing what pressure your RV needs when it is fully loaded or when it is empty.If you stick to this information on the label, you will comfortably determine your RV's correct pressure.
