How to Deflate Your Tyres

Staun tyre deflators are by far the quickest and easiest way to reduce tyre pressure - say goodbye to the hassle of fiddling around with keys, matchsticks or poor quality devices.

Basically all you have to do is screw a deflator onto your tyre valve stem and then leave them to do all of the work - YOU DON’T EVEN NEED ANY TOOLS TO USE THEM!

Deflators are supplied at a preset pressure

The deflators are supplied at a preset pressure, however you can adjust this pressure to your desired level. It is not necessary to reset them again unless you wish to change the psi that you want to reduce your tyre pressure to.

Exactly how much you reduce your tyre pressure depends on a variety of factors, such as how much weight your tyres are supporting. Additionally the softness of the surface that you are travelling on will also affect how much you need to let your tyres down. Through trial and error you can find your personal preference and determine what tyre pressure suits you.

Staun Tyre Deflators do not have a minimum start off pressure so you do not need to bring your tyre pressure back up in order to reduce it further. Simply turn the adjusting cap anti-clockwise to further reduce your tyre pressure. If they do not start automatically you can manually start them by lifting the pin. Please check your product header card for individual pressure settings.

The Staun Tyre Deflators need to be screwed on using the finger grip located at the base of the deflator body. Do not use the adjusting cap or lock ring to fix the deflator to the valve stem. For a comprehensive demonstration on how to install the deflators onto your tyres please view the video above.

This model comes preset at 7 psi and has an adjustment of 2 psi per half turn and 4 psi per full turn of the adjustment cap. It also only requires 2 psi above its preset pressure to start automatically, but can be manually started by lifting the pin as little as 1 psi above the preset pressure.

Staun Tyre Deflator - Standard (6-30psi)
SCV5

This deflator has been designed to suit most 4WD deflation needs. Suitable for beach or bush pressures it comes preset at 18psi and is accurate to within 0.25psi.

It has an adjustment of 3psi per half turn and 6psi per full turn of the adjustment cap. Requiring 12 psi above its preset pressure to start automatically, they can be started manually by lifting the pin at as little as 2 psi above its preset pressure.

Staun Tyre Deflator - Heavy Duty (15-55psi)
SCVHD

The heavy duty deflators are distinguished from the standard by having an extra exhaust hole.

This deflator is designed to deflate to and from higher pressures. It is also accurate to within 0.25psi. Designed for use in the light to heavy trucking industry, it is also suitable for agricultural and farming equipment.

This model comes preset at 35psi and has an adjustment of 4psi per half turn and 8psi per full turn of the adjustment cap. It requires 20psi above its preset pressure to start automatically or can be manually started by lifting the pin at as little as 2 psi above its preset pressure.

Staun Tyre Deflator - Camper Trailer Pack (4 at 6-30psi and 2 at 15-55psi)
SCV5/HD

This unique set comes with 4 Standard deflators and 2 Heavy Duty deflators. Designed to suit those who tow camper trailers and vans off road and on the beach. While your 4WD tyres are deflated to your preferred pressure, the trailer would normally deflate to different pressures based on the weight of the trailer/van.

This set allows you to deflate your 4WD and trailer at the same time without having to adjust your 4WD deflators to deflate your trailer/van. Your 4 Standard deflators are preset at 18psi and the 2 Heavy Duty deflators are preset at 22psi.

I was extremely pleased with the performance of these Tyre Deflators! It's so simple and quick to air down now. Now all I do is walk around to each tire and screw on the Staun deflators, when the air stops releasing I know the tires are done. Besides that each tire is 100% exactly the same pressure as the rest.
