6 Best Tire Deflator Tools for Airing Down Off Road With Ease

6 Best Tire Deflator Tools for Airing Down Off Road With Ease

You want to waste as little time as possible on an off-road adventure. Unfortunately, if you’re going to set tires up for success against rough and loose gravel surfaces, you’ll need to use a tire deflator tool. You can end up in a sticky situation if you head out for an overlanding adventure without a tire deflating tool.

Today, we’re sharing six of the best tire-deflating tools that make it easy to air down your tires while off-roading. Let’s get started!

Why Do You Need a Tire Deflator?

If you do almost all your driving on solid road surfaces, you likely won’t need to use a tire deflator. However, a tire deflator comes in handy for those who like to take their vehicles off-roading on surfaces with loose gravel. 

Airing down your tires in these situations helps to increase the surface area between the tire and the road surface. This increases traction and can help vehicles avoid getting stuck when driving on loose road surfaces.

Tire deflators help you to quickly and easily reduce tire pressure. Some versions of tire deflators will monitor the air pressure and stop letting air out once they reach a specific pressure. This can help you avoid deflating your tires too much and causing a flat tire.

How Does a Tire Deflator Tool Work?

There are a few types of tire deflators. The three types are pre-set screw-on tire deflators, e-z tire deflators, and primitive tire deflators. They do the same job, but how they do it is different. 

Pre-set screw-on tire deflators screw onto the valve and put pressure onto the valve core. This releases air from the tire, pushing a spring inside the deflator. Once the air can’t overpower the spring, the tire deflator closes and stops the air from leaving the tire. These deflators can take some time as they slow down while the tire pressure lowers the tire.

E-Z tire deflators remove the valve core to allow an extremely fast flow of air from the tire. These deflators will enable you to remove 1 PSI per second. However, if you’re not careful and watching your tire pressure gauge, you’ll let too much air out of your tires. So make sure you’re paying attention when using this method.

Finally, if you don’t have one, you can use some primitive tire deflators. All you need to do is press in on the valve core with a sharp object. You can use a screwdriver or rock to press in on the core and let the air out of your tires. You’ll want to frequently check how much pressure is in the tire to avoid removing too much air. Be careful not to damage the valve stem when using this method.

#1 Staun Automatic Tire Deflators

They screw onto your tires and reduce the air pressure to the pre-set level between six and 30 PSI. However, they come with a premium price tag ($100) compared to other options.
