Getting tire deflators speeds up the process of getting your tires to the best PSI for riding trails and offroading.
If you pick up some automatic tire deflators you can have a set PSI you like your tires at and just screw them in. Then walk away – they’ll stop when they get to the right pressure. It’s a simple process that takes a bit of pressure off you(bad pun).
Let’s take a look at the best tire deflators available:
1. ARB ARB505 E-Z Deflator, Orange
ARB’s EZ deflator is a simple solution for offroaders.
This kit has an adjustable brass hardware gauge and includes a carrying bag. It’s one of the most popular options and for good reason, ARB is a well-known brand and their products just work.
You won’t break the bank either. If you want a simple setup and don’t mind it taking a bit more time than an automatic deflator. But, when we say “a bit more time” it isn’t much, maybe 3 or 4 minutes max. This is a great choice and value overall.
2. Staun Automatic Tire Deflators (Standard Duty 6-30 PSI)
The Staun Automatic Tire Deflators are well.. automatic. That’s the point.
You can adjust these to the PSI of your choosing, then just set and forget. They have 3 different models covering PSIs between 1 all the way up to 55.
If you’d like your tires to be anywhere in that range and want an automatic option, you can get that with these. They’re made in Australia from solid brass. These are on the higher end of the price bracket than most competitors.
But, the big benefit is you get four solid pieces and you don’t have to rely on any hosing or valves. While other kits with more parts could wear down over time, you won’t have the same issues here. They’re a great for a compact solution that will last a long time.
The product we’ve linked to here covers the 6-30 PSI range, make sure to select the range that suits you best on the product page.
3. Boulder Tools All New Heavy Duty Rapid Tire Deflator Kit with Valve Caps, Valve Cores & 4-in-1 Tire Valve Tool
Boulder Tools has a very affordable tire deflator kit. If you are looking to save money and you’re not too keen on automatic deflators, this will do it. It does have a very solid construction, but it also has a lot of parts.
For simplicity sake, it might not be the best but they have a solid reputation and top it off with a 1 year warranty. It comes in a handy carrying case with plenty of extra parts. The tire pressure gauge is a handy way to keep track of your progress.
4. BILLET4X4 TRAILHEAD Tire Deflators
Do you guys think Billet wants you to know their products are made in America? We do, and suddenly we’re feeling very patriotic.
Their automatic tire deflators can get you from 1 to 55 psi. The deflator kit includes a pressure gauge and a nice pouch in addition to the hardware.
Calibrating these can be a bit of a pain, but really it’ll just take a few extra minutes. You’ve got to set it, and check it that it deflated to the PSI you wanted. For each one of these this process requires a bit of work with a real tire. An air pump will be handy so you can keep refilling until you get it just right.
How do tire deflators help?
When you’re driving around every day on paved roads, it helps to have your tires pumped up to the recommended PSI. It saves you gas, and it’s easier on your car. Once you decide to go offroad and start dealing with uneven surfaces, deflating your tires gives them a bit more slack to sink into something.
For an example, let’s imagine you’re trying to drive over a large branch. Your tires are pumped up though, and when you can’t make it – they start to spin. As your tires rub against the branch there is no give, and they do not conform to the shape of the object they’re trying to move past.
In the same example, let’s imagine you have properly deflated tires. You approach the branch and instead of your tires spinning against the object – the slack provided by less air allows your tire to “grip” the form it needs to overcome.
As you can see this is a huge advantage when it comes to offroading.
Automatic tire deflators are neat, but they do cost quite a bit more than single piece kits. The Billet deflator kit is our favorite when we considered overall value.
A quick note about automatic deflators is that you don’t necessarily need 4 of them. By the time you put all four on your first tire might already be deflated. They can be bought individually and we’ve seen some offroaders suggest that they only needed two. It’ll be more affordable to buy a couple instead of a set.
Let us know if you pick up something from this list and how it worked out for you. Good luck on your search.
