A reliable tire deflator is essential for airing down before hitting the trail. While you could use a stick to depress the valve stem, it doesn’t offer precision and could damage the valve core. Airing down offers a smoother ride, especially on rocky or bumpy terrain. With full air pressure, your tires are stiff, making every rock and bump more noticeable. Lower air pressure makes tires more flexible, allowing them to conform to the terrain and absorb impacts, resulting in a more comfortable ride.
The ARB E-Z deflator is one of the most popular options, backed by a trusted brand with decades of reliability.

When researching tire deflators, you’ll find many options, but the ARB E-Z Deflator is a solid choice to start with. ARB also offers a comprehensive recovery gear starter kit, ideal for those new to off-roading. The premium kit includes a Snatch Strap, Ultralight Snatch Block, Tree Trunk Protector, and two 10k lb 3/4-inch Pin D-Shackles. Off-roading and overlanding can be unpredictable, so being prepared with the right gear is essential for any adventure.

ARB Off-Road E-Z Deflator Overview
The ARB easy deflator tire gauge features a full geared, solid brass precision movement with bronze bourdon tube.
Wait, what is a bourdon tube? A bourdon tube is an instrument for measuring the pressure of gases or liquids, consisting of a semicircular or coiled, flexible metal tube attached to a gauge that records the degree to which the tube is straightened by the pressure of the gas or liquid inside.
There are many other types of air pressure deflators out there that feature plunger-type gauges.
These other gauges are likely to be affected by changes in the temperature, humidity or altitude.
The ARB E-Z deflator has been tested for accuracy before shipment.
Is it worth the extra money for this Air Deflator?
I think so, yes.
The ARB E-Z Deflator is a durable, high-quality tool that will last through your 4×4 adventures and beyond. It’s easy to use, comes with a sturdy case that fits small tools like a pocket knife or flashlight, and packs compactly. Unlike bulkier deflators, its small size makes it perfect for freeing up space in your 4Runner while still being tough and reliable.
The next best smaller option would be a set of Staun Deflators or Coyote Enterprises Deflators, however, those two options are on the pricey side. But, there are companies like Boulder Tools and others who make a cheaper version but some reviews suggest the ending PSI may vary.
Parts of the ARBÂ E-Z Deflator
- Internal Thread: Front portion that threads onto your valve stem
- Slide valve. Push forward to hold/read pressure & pull back to bleed air pressure
- Valve Stem Adapter Handle: Screws head of unit on two valve stem
- Valve Core Handle: Screw clockwise to insert valve, anti-clockwise to remove valve
How To Use the ARB E-Z Deflator
1. Thread on Valve Steam
2. Push Lightly & Turn to Remove Valve
3. Push in to Read Air & Pull Out is Release Air
4. Push in Lightly and Tighten Valve
5. Remove Unit
Once you’ve screwed on the internal threading to the valve stem using the valve stem adapter handle, move to the valve core handle. To lock the valve, slightly push the valve core handle in, then turn counterclockwise to engage the lock. After the valve is locked, continue turning counterclockwise to pull out the valve stem. Once the valve core handle pops out, slide the valve back to release pressure. Push it back in to read your tire pressure. It took me a minute to figure this out on the trail, so hopefully, this explanation helps you avoid any confusion.
Step By Step from the instructions: How to Use the ARB EZ Deflator
- Step #1: With the slide valve pushed forward, thread the valve stem adapter onto the valve stem in a clockwise direction.
- Step #2: Push the valve core remover forward until engages the valve and turn anti-clockwise to remove the valve.Â
- Step #3: When the valve core is removed it will push the cork remover out and the gauge will read the tire pressure.Â
- Step #4: Pull out on the slide valve to release air. Push in on the slide valve to stop air and check the pressure. Note, Gauge will not show correct pressure wall deflating.Â
- Step #5: Space when the desired pressure is released push the valve core remover in and turn clockwise until the valve seats firmly. Note do not over tighten the valve core.Â
- Step #6: Remove the unit by turning the valve stem adapter in an anti-clockwise direction. Ensure a valve cap is placed on the valve stem to prevent ingress of debris.Â
Caution: Do not exceed the maximum pressure on the dial. Accuracy can be impaired by dropping or severe jarring.
Warning:Â To avoid the possibility of an injury, eye protection should be worn when using this gauge or when attempting to d0 any tire repairs.Â
ARB Air Inflator
The ARB air inflator is an essential tool for re-inflating your tires after airing down. Unlike gas station inflators, which lack a gauge, the ARB inflator lets you monitor your tire pressure as you fill them, saving time and ensuring accuracy. This is especially convenient after a trail ride, as it eliminates the need to repeatedly attach a pressure gauge.
If you want to take your inflation/deflation to the next level, you can look at the MORRflate 4-way inflation/deflation system.
Going a step further with On-Board Air?
Onboard air systems, such as those offered by ARB, provide mounted air tanks for your vehicle, ranging from $150 to $500+. These systems vary in price based on features, with more advanced setups like CO2-filled PowerTanks supporting air tools and multiple pressure lines. While onboard air is a great addition for serious off-roading, it’s not necessary for everyone. Be sure to research and choose the system that fits your needs before purchasing.
I bought this deflator and I’m having hard time with it. I finally figured out how to let the air out, but reading the PSI’s was way off. The gauge would jump up and then back down. Nothing was the same. I used it a couple of times and decided to return it.
I gotta say, I had a bad experience with this deflator the first time I used it! I mistakenly pushed too hard on the core valve stem and broke it. The result was that the air rushed out of the tire when I removed the deflator. I had no way to stop it. I eventually had to change the tire. It was definitely user error on my part. I should have practiced at home first too. But I do wish the instructions had warned me more!
Tom, that’s a bummer. You may have better luck with a set of the Staun Deflators, similar to the Coyote Deflators, or even the upgraded version of the ARB analog deflator, the ARB digital deflator.
