Best Tire Deflators & How Do They Work
Quick Answer – Best Tire Deflators:
On the long distance journeys in your overlanding rig or truck, you will come across special circumstances where you need to deflate your tires. Beaches, sandy tracks, and trails are a few areas where you will need a reduced tire pressure to counter the loss of traction.
In these situations, you will need the best tire deflator available to get your tire pressures to be at the right levels quickly to get you and your rig across the challenging terrain.
Tire Deflators – Why Are They Essential For Overlanding Adventures
In the soft sandy ground, a fully inflated tire will sink down when you attempt to drive your truck or rig through it. The point of contact between the tires and sand is narrower, making it easier to sink into soft ground.
Sunken front tires always have a raised wall of sand in front of them. When you try to accelerate, the tires keep pushing against these berms with little or no success.
Due to the loose nature of sand particles, tires dig further into the ground when pushed, increasing the size of the wall or berm of sand in front of them. Ergo, we get stuck for good.
When you deflate a tire, it flattens and lengthens at the point where it touches the ground. This increase in contact area or footprint of the tire. A tire with a longer footprint will not dig as deep into the sand as a fully inflated narrow tire.
It is common belief that a deflated tire get wider, but the truth is, the footprint actually gets longer, but not wider.
Advantages of deflating a tire are many and go beyond just getting us unstuck. Some of the other benefits include:
- Fully inflated tires end up with a lot of wheelspin, which can lead to wearing down of the tires and track damage. Deflating the tires helps avoid this.
- Sharp objects are a dime a dozen in offroad tracks. They can and will puncture fully inflated tires. Softer and flatter tires have less chance of getting punctured as they roll over them.
Now, there are several ways to get your tire pressure down. If you want to go full Flintstones, you can use a sharp stick or stone to open the pressure valve of your tire and let some air out. In a pinch, this is a useful trick.
But when you are overlanding, sand and loose dirt/gravel is an everyday adversary. You need something from the “Jetsons,” an advanced tool that gets the job done quick, clean, and under total control. Enter the Tire Deflator.
With the best tire deflator, we get several crucial advantages over the sticks and stones approach:
- It is a unique tool designed to work with tires, so there is minimal chance of damage to the valves.
- A tire deflator saves you a lot of time. Using one is as simple as one, two three. You don’t have to hunt for that perfectly shaped stick!
- It removes the guesswork from the equation. The best deflator will tell you the exact PSI of the tires, and allow us to deflate it to the precise pressure level we want.
- They are also incredibly compact. When going on overlanding adventures, we have to travel as light as possible. And the best tire deflator is compatible with this philosophy.
Tire deflators come in two basic designs:
- Pre Set Screw On Tire Deflators – relatively simple devices where you set the level of PSI you want to reduce in advance before connecting to the tire.
- Fast Tire Deflators With Gauge – these are bigger and come with a pressure gauge that allows you to adjust the PSI level on the fly.
