What Is an Off-Road Air Compressor?

An off-road air compressor is a portable and lightweight model that quickly inflates vehicle tires. These are essential tools for those planning to take their rigs off paved roads. 

Most serious overlanding and off-road enthusiasts have a portable air compressor with them at all times. Some even have onboard units installed on their truck or SUV. When off road its important to be self sufficient in the case of a flat, but most of the time they are used for airing down.

If we’re going to be off-road for more than a few miles we almost always air down our tires.

Pro Tip: When overlanding in remote locations, it’s critical to be prepared for any situation. In addition to an air compressor, make sure you carry these 11 top essentials.

Why Do You Need an Off-Road Air Compressor?

Its said that one of the best traction modifications you can make to your vehicle is simply letting air out of the tires. Airing down tires improves their traction by giving them a larger footprint and allowing them to smush into the terrain. Airing down also significantly improves the ride on rough terrain. However you cannot run with low tires at high speeds on the road, they will fail. Hence the need for a powerful air compressor to get you back to pressure before hitting the blacktop at the end of trail.

At the end of your overlanding adventure, you’ll likely want to get back on the paved roads to go home. However, driving on underinflated tires on paved roads can cause permanent damage. The tire temperatures will significantly increase and even result in a tire blowout. 

Having a quality off-road air compressor means you can quickly inflate your tires to the proper levels before hitting the road.

➡ Whether you’re on dirt roads or paved, an overland GPS can help get you where you need to go. Here are your 5 best options.

Onboard vs. Portable Air Compressor for Off-Roading

You’ll typically find two types of off-road air compressors. Whether you choose an onboard or portable air compressor largely depends on your vehicle and your needs.

Onboard

Many overlanders use onboard air compressors if they have room. They do take up space under your rig and cost more, but you can store more air. Onboard units can also help with air suspension and air horns.

Onboard air compressors are usually installed underneath the truck or SUV.

An onboard air compressor can do the same job as a portable one but faster. You can do the same job in as little as 1/3 of the time.

This may not sound like much, but you’ll likely save 10-15 minutes each time you need to inflate all of your tires. If you’re spending the entire weekend transitioning from off-road to highway driving, it’s a huge time savings.

Portable

A portable off-road air compressor is a fantastic option as well. This is a more cost-effective choice and great for those who need to inflate or deflate their tires on occasion. Because they’re portable, you can move them from your motorhome to your Jeep or from your daily driver to your overland truck and use them in various circumstances.

Portable air compressors don’t typically have large tanks. This means they’ll likely need to run harder and longer than air compressors that can store air in a tank. It will also take longer to inflate your tires since the compressor may need time to rest if you’re working it too hard.

A portable air compressor is easy to store and carry and can be transferred to your other vehicles as needed.

If you want to top off your vehicle’s tires, air up e-bike tires, or blow up an air mattress, a portable off-road air compressor is excellent to have. You can store it under a seat or hide it in the back of your vehicle, and it’ll be ready to do the job when you need it.

The onboard Oasis sounds great but what about water? It looks like driving thru standing water or even puddles and that thing is done for. It is waterproof?

Have a Grenadier on order and wonder about how to handle inflation after a beach trip. Portables seems slow not having a tank, would rather have a tank on board. Perhaps the answer is a tank storing air and use a portable to top off the tank as needed. hmmmm

Good morning, I really enjoyed this article on air compressors. I am interested in driving on the beach and would like more information about inflation and deflation of tires. My tires currently are 80 psi, what should I deflate them to for driving in the sand? I have heard down to 30-40 psi. Is that going to damage my tires? I am looking for some more information regarding this subject. Any help would be greatly appreciated.

I am planning on writing an article all about this, but its primarily going to depend on the weight of your vehicle. Some tires have inflation charts and will tell you. Running that low should not be a problem at all, in fact you should be able to go lower. Its just the operational speed that is a concern with the lower pressure. Driving too fast flexes the rubber too much and overheats them. The lower you go the slower you need to drive. Our 80PSI tires we take down to 20 in the front and 35 in the back on our 17,000lb overland vehicle. These are military tires and we have the speed/load/inflation charts for the tire.
