What Is a Tire Deflator?

A tire deflator allows you to reduce tire pressure to a reasonable level to enhance tire stability on uneven surfaces and prevent bounciness. The common types of tire deflator are the simple nut and gauged.

Simple Nut Tire Deflator

A simple nut tire deflator usually comes in a set of 4 that you can screw on all of your tires to minimize air pressure at once, without having to move back and forth. It’s useful in a sense that it obviously saves you the time and effort figuring out if you’ve correctly deflated your tires because you can just automatically set it in advance, to the appropriate units Per Square Inch (PSI).

At a glance, it’s made from brass material and runs on spring. The brass body with plunger is inserted in the valve stem, while the valve stem’s pen-like structure sucks the air in and expels it out through the two holes.

Gauged Tire Deflator

As the name suggests, a gauged tire deflator reconciles two separate benefits that you can get from the simple nut design and typical scale. This is because it lets you reduce the amount of tire pressure while giving you a reading on the air drop level.

One good thing to note about a gauged tire deflator is the fact that many of its designs are known to drop tire pressure in as fast as 1 PSI per second. Although you need to give only the right amount of tightness because over doing it can force a large air volume to seep out.

Furthermore, many tire deflators of this type don’t provide an exact reading as most of their gauges are based on precision (or close estimation) rather than accuracy.   

1.  ARB Tire Deflator

When you’re very particular with getting the right amount of air pressure out of your tires, turn to ARB ARB505 E-Z Deflator Kit.

What makes this tire deflator special is the fact that it consists of tick marks under the 10 scale which gives you an accurate measurement of PSI below it.

This is because most tire deflators don’t have such a feature, making it difficult to obtain such measurements.

Plus, it provides you with the combined benefits of a unit tasker and a pressure gauge which eliminates the hassle of using such gear separately.

ARB Tire Deflator
Pros:

  • Capable of performing very accurate measurements under and above standard scale.
  • Resists rust.
  • Affordable.
  • Quickly decreases tire pressure.
Cons:

  • Practice using on several tires of various 4x4s to check valve stem compatibility.
  • Practice deflation process to achieve desired results.

2.  Boulder Tools Tire Deflator

If you hate the idea of setting your tires’ PSI every now and then, getting the Boulder Tools Tire Deflator Kit is a wise choice.

This tire deflator easily secures your particular PSI preference that you no longer have to reset it every so often, which saves you time, especially if you need to get back on the trail. But if you don’t like waiting for a few minutes before deflation stops, check out the 1-minute deflation trick.

After you’re done deflating your tires, you don’t have to worry about potential air leaks as long as you take advantage of its 360-degree swivel chuck tip.

It also has a rubber cover that prevents slipping accidents and protects it from damage.

Boulder Tools Tire Deflator
Pros:

  • Easy to setup.
  • Affordable.
  • Effectively reduces tire pressure in a uniform way.
  • Reasonable design and functionality.
Cons:

  • Storage case is only made from hard plastic.
  • Gauge isn’t 100% accurate.
  • Takes 10 minutes for deflation to end.
  • Whistles loudly if not secured properly.

3.  Staun Tire Deflator

When the waiting game is never a part of your tire deflation itinerary, trust Staun Tire Deflator to make things quick and easy.

This tire deflator is remarkable in a sense that it automatically airs down your tires and abruptly stops when it reaches the required PSI.

Best of all, it comes in 4 pieces to help you easily deflate all your tires at the same time. This is very convenient especially if you usually experience back and knee pains for bending too long a period.

It is also easy to adjust as long as you stick with its instruction manual.

Staun Tire Deflator
Pros:

  • Small leather pouch says a lot about portability.
  • Available in 3 models based on your 4x4ing preferences.
  • Increases your productivity during idle time.
Cons:

  • Most expensive of all tire deflators.
  • Verify tire pressure via test drive before embarking on an actual trail.

4.  EZdeflator Tire Deflator

If you’re looking for a tire deflator with a perfect union between budget-friendliness and functionality, the EZdeflator Universal Tire Deflator Kit fits the bill.

This is because such a tire deflator is very inexpensive at only $19.95 yet it delivers a deflating efficiency that almost matches its high-end counterparts.

The nuts can be stored in a case specially designed with holes to secure them in place and reduce the possibility of unnecessary bouncing.

Moreover, it has a minimum PSI of 6 which is also below the usual range of 10.

EZdeflator Tire Deflator
Pros:

  • Most inexpensive of all tire deflators.
  • Comes with a lifetime warranty.
  • Also automatic like Staun tire deflator.
Cons:

  • Setup takes 30 minutes.
  • Gauge isn’t 100% accurate like Boulder Tool tire deflator.
  • Needs petroleum jelly to boost accuracy.

5.  Grit Performance Tire Deflator

In terms of the fastest air down time, the Grit Performance Rapid Tire Deflator Off-road Kit easily brings home the bacon.

What makes this tire deflator standout from its competitors is its unique no-valve-core design that lets you speed up the air expelling process, which only takes 15-20 seconds.

And if you happen to suddenly come across the need to deflate your tires somewhere dark, you’ll still be able to do so because its gauge is luminous.

Furthermore, its bronze tube and brass deflator are rust-resistance for improved longevity.

Grit Performance Tire Deflator
Pros:

  • Shortest air down time.
  • Includes valve core replacement if necessary.
  • Storage bag is made from hard shell for a good amount of protection.
  • With lifetime warranty like EZdeflator tire deflator.
Cons:

  • Instructions can be hard to follow.
  • Gauge lens is only made from plastic.

Difference Between a Tire Deflator and Tire Inflator

Never get confused with the function of a tire inflator and tire deflator. The simplest explanation to both is that the former is used to increase tire pressure but the latter is used to decrease it. However, to help you fully understand it, it’s best to know when each is used under certain circumstances and who benefits from them.

  • A tire inflator is used when you travel on roads and highways. Due to the high volume of motorists and varying speed limits in such places, deadly collisions often happen and increasing your tires’ pressure makes your vehicle’s brake and steering responses quick.
  • A tire inflator is used to prevent overheat. When a tire has insufficient pressure on regular surfaces, it has a tendency to flex which leads the way to further heat generation. If the tire is inflated at a recommended level, it won’t happen and your tires’ lifespan is preserved.
  • A tire inflator is used to prevent your tires from snapping. Don’t get us wrong but if you often put too much load on your vehicle’s cargo area, you need to amp your tire pressure based on its maximum load number, unless you don’t mind frequently buying new tires.    
  • A tire deflator is used to improve traction on soft or uneven ground. If you’re an off-roader who enjoys a ride on the dunes or snowy fields, you have to air down on your tires’ pressure to keep your tires afloat, since soft surfaces can easily sink them.
  • A tire deflator improves tire stability during rock crawling. If you’re an off-roader who’s after the ideally slow yet steady climb on steep, rocky trails, decreasing your tires’ pressure makes your tires bendable and follow rock shapes, which reduces the risk of a rollover.
  • A tire deflator keeps your tires in running condition during racing activities. When participating in off-road racing events, decreasing tire pressure whenever you need to also maximizes performance and keeps you safe.

Conclusion

A tire deflator is one of the 4WD accessories that off-road enthusiasts should have. This is because regardless of your 4×4 build, it lets you maintain your tires’ solid grip on surfaces which can otherwise tip you upside down and lead you rolling to your doom.
