Best Portable Air Compressor for RV Tires – 2020 Top Picks

Before setting out on a road trip, it’s important to ensure that your RV’s tires are properly inflated.

If the tires happen to be under-inflated, you cannot wait until you’re at the gas station to restore pressure.

A buildup of excess heat as you drive can cause tire failure. Besides, too little air pressure can negatively impact the tires’ durability and may also affect your RV’s braking and handling systems. Over-inflated tires, on the other hand, can easily sink into loose sand, mud or trail dirt. It’s for these reasons that we review the best portable air compressor for RV tires.

What you need to know?

The quality of an air compressor boils down to its ratings. The first of these is the Cubic Feet per Minute value (CFM). It measures the speed at which air is delivered to the compressor tool. The higher the CFM rating, the more powerful the compressor. The other important rating is the Pounds per Square Inch (PSI). This gives the force at which air is delivered by the compressor. For RVs, a PSI of 40-90 can get the job done. Lastly, we have Horsepower (HP), which measures the work capacity of the mortar that drives the compressor pump. A higher horsepower translates to a higher CFM.

What to look for in portable compressors?

In addition to ratings, weight should be a major factor to consider before making a purchase. A portable compressor should be light enough to be carried around by hand. Let’s face it! You surely wouldn’t fancy dragging around a 100-pound device even if it has wheels. A compressor weighing 40 pounds or less would be ideal. Besides, lighter units are smaller and easier to store.

Does the tank size matter?

The tank size determines the maximum volume of air the compressor can hold, usually measured in gallons. Although a large tank is desirable, perhaps a smaller unit is preferable for use on RV and motor homes to facilitate transport. However, it’s important to ensure that the compressor has a high PSI. Here’s why. A compressor with a small tank and a high PSI recharges continually, thereby giving prolonged operation time.
