Why Do You Need to Deflate Your Tires?

As mentioned, reducing the pressure in your tires while off-roading is one of the best performance gains you can get. Why? Well, imagine a basketball. A fully inflated basketball bounces like crazy while a partially deflated basketball hardly bounces at all. In this case, your 4×4 vehicle is the basketball. More air in your tires leads to a bouncier ride. 

What Is a Tire Deflator and Why Not Just Deflate Yourself?

A tire deflator allows you to easily and quickly reduce tire pressure. That first part, easily and quickly is key here. You can deflate your tires without tire deflators – just put a stick in the inflation valve and watch the air come rushing out. But there’s a problem with this : using a stick will take a long time and you have no idea how much pressure is being released without continuously checking your pressure back and forth with a pressure gauge. If you’re in a bind, sure, deflate the pressure on your own, otherwise pony up the $50 and get a set of deflators.

Two Types of Tire Deflators: Nut Tire Deflators & Gauged Tire Deflators

Let’s discuss the two types of tire deflators you’re going to encounter: nut tire deflators and gauged tire deflators. 

Simple Nut Tire Deflator

Simple nut deflators are easy to use but lack a pressure gauge.

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. The beauty of them is that you set the desired pressure on the nuts before hand, screw them in your tire, and watch as your tires automatically get deflated to the target PSI.

Gauged Tire Deflator

Gauged tire deflators have a built in pressure gauge that allows you to accurately and visibly watch your tire pressure decrease to a give PSI. They also have the added benefit that you can use them to see the PSI of your tires even when not deflating them. 

What Tire Pressure Should You Decrease To When Offroading?

Alright, so the million dollar question: what pressure should you decrease your tires to? There are a lot of variables used in deciding the desired PSI, but here’s a some general rules of thumb for the optimal PSI of your tires according to terrain.

Terrain Type Tire Pressure
Regular Roads 30-38 PSI
Firm Dirt & Normal Gravel Track 28-36 PSI
Rocks 22-28 PSI
Rough Gravel Track 26-32 PSI
Sand 15-18 PSI

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.


A tire deflator is one of the 4WD accessories that all off-roaders 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.
