The best tire deflators can come in awfully handy for off-roaders. Tire deflators come in various forms and each allows drivers to quickly and precisely deflate or ‘air-down’ their off-road tires when required for enhanced grip, traction, and adaptability in challenging terrain. You can get the best automatic tire deflators or a more budget friendly option, but all will get the job done.

Though most motorists know that maintaining proper tire pressure is vital to safety performance and fuel efficiency, certain situations faced by off-road drivers require tires to be run at a low pressure, which makes the tires more flexible and grippy. With a tire deflator, drivers can quickly air down their tires to tackle a challenging obstacle or path, and then re-inflate later once the way is clear.

Tire inflators all do the same thing—but they work in various ways, and not all products are created equal. If you’re after a tire deflator kit, you’ve got numerous options at a wide range of price-points. Here’s a closer look at some of the best tire deflators currently available.

1. Editor's Pick: ARB E-Z Deflator

Topping our list of the best tire deflators is the ARB E-Z Deflator. For a few bucks more than the cheapest options listed below, the ARB E-Z Deflator features a stylish carrying pouch, solid construction, the backing of a well-known brand, and excellent owner reviews. With built-in corrosion resistance and special provisions for enhanced pressure-reading accuracy, even in varying temperatures, the ARB E-Z Deflator makes airing down your tires quick and exact. The fully-geared brass precision movement and 1-PSI increments provide a highly precise pressure reading in real time, too.

Just note that fully manual operation means you’ll need to watch the dial to stop the deflation process for each tire and that this product requires users to remove the valve core on each tire prior to use. This makes the deflation process faster. Owner reviews of the ARB E-Z Deflator are generally positive and point to satisfaction with the performance, ease of use, and quality for the price point.

2. Best Pre-Set Deflator - Staun Automatic Tire Deflators

Whether handling rocks, sand, mud or snow, these deflators make airing down a total cinch by simply screwing on the Staun tire deflator and then removing it once it stops deflating. Simple as that.

8. Potek Portable Power Source

After deflating the tires on your off road rig, you absolutely need to inflate them back up to the proper pressure for highway use to avoid damage, wear and ill handling. Enter the Potek Portable Power Source—which combines numerous functionalities into a single portable unit that takes up minimal space inside your truck or Jeep. Powered by your vehicle’s battery, the Potek Portable Power Source is a power bank, jump starter, safety light, and more in one convenient package.

The Potek Portable power source also features a built-in 150-PSI air compressor complete with built-in pressure gauge, for accurate inflation. Most owner reviews are in the 4 and 5 star range, citing solid functionality and a decent price as prime purchase considerations. Just note that inflating a tire may take some time, and that the unit is manual—meaning you’ll have to spend some time waiting for each tire to inflate, monitoring the pressure in the process. Further, some owners say the LED safety light isn’t bright enough to be useful.

What makes the Staun product better than any other like the ARB deflator?

Systems like the ARB deflator require you to air down your tires individually and monitor them in the deflation process so you can stop at your desired tire pressure. With the Staun deflators, you can just screw them onto your valve stem and they do all the work for you by automatically stopping when you get to your desired air pressure. Sure it takes some work on your part at home to set them to your pre-desired air pressures, but once they’re set, airing down is effortless and quick. You also take less chances of losing your valve core in the dirt, which can totally ruin your day if you don’t have a backup.

Do I need to check my tire pressures after using these products?

While some of these kits have built-in pressure gauges or allow you to pre-set your desired tire pressures, we still highly recommend keeping a good quality tire pressure gauge in the cab of your rig. It never hurts to double check your pressures to ensure that either your pre-set deflators or built-in gauges are still accurate.
