Airing Down with the
Staun Tire Deflators
|
Click to zoom |
 At the trail head,
one of my common preparation routines just before hitting the trail
is to air down to a desired tire pressure for the terrain. Typically I'd go from one
tire to another with an air gauge and letting the air out, checking the
pressure, letting more air out and so on until I hit the pressure I wanted ...
on each tire. Later after a long day of 4-wheeling I'd air up before
hitting the road home. On some trips where there was that pressure to hit
the trail immediately, and I always felt like I was rushing around, trying to
air down, disconnect the sway bar, lock the hubs, put gear in the cab with me,
get the drinks in the handy cooler, get the camera ready ... all kinds of stuff.

 Airing
down took up most of the prep time because was stuck at 4 tires,
letting air out and checking the pressure. As my offroad
tires got more serious and I got more serious, my tire pressures got lower.
That just meant I spent more time at each tire airing down. In the winter,
that meant cold air on the fingers. I hated that. Maybe I'm getting
lazy as I get older but I finally broke down and spent a few bucks on the Staun
Tire Deflators. |
| When I considered buying these I figured it would be nice
to screw on a set of these, do the rest of the prepping while they aired the
tires down to their pre-set pressure, and stopped. When I bought them, I
found that these Staun Tire Deflators were pretty impressive little tools.
Their brass construction and leather pouch gave them some substance and a heavy
duty feel. The leather pouch is nice, keeping them safe when stashed. |
 The
most impressive thing about these tire deflators is the fact that they are
easily adjustable to the tire pressure I wanted to run and are accurate down to
.25 psi. That's 1/4 of 1 psi. My digital tire gauge isn't that
accurate. They weren't cheap, costing about $55. for the set of 4.
But when I compared it to deflators that didn't stop at any air pressure and
just kept deflating until I got back to the tire to check the air pressure,
well, why bother? Even the cost of those wasn't cheap. So I figured
if I was going to buy something, I might as well get something I'll appreciate.

 Using
these Staun Tire Deflators couldn't be easier. I just
screw them on and walk away. The pre-adjusted spring loaded pressure
regulator stops releasing air when it gets down to the desired pressure.
Then you take them off. That's it. No more crouching down with an
air gauge or holding the valve stem in with a stick or the pressure gauge.
Adjusting them to the pressure you want to air down to is
just as easy. To do so, you do the following: 1) Deflate a tire down to
your preferred tire pressure. 2) With the lock ring and the adjuster cap wound
down , you screw the Staun Tire Deflator onto the valve stem. 3) Loosen
the cap counterclockwise until the deflator pops open and air begins to release.
Then immediately tighten the cap to the position where the air stops releasing.
4) Turn the lock ring up to meet the adjuster cap. Don't turn the adjuster
cap, just screw the lock ring tight up against it. Do this for each Staun
Tire Deflator and that's it. They adjust at about 3 psi per half turn of
the adjuster cap.
Once I started using these Staun Tire Deflators, I find
they were well worth the money. Beside the cool factor of airing down
without hovering over a tire, they are quick and effortless. Just be sure
that when your buddies borrow them (you know they will), you get them back. |

Available in three ranges: |
|
Light Duty |
0-10 psi (code SCVLD) |
|
Standard |
6-30 psi (code SCV5) |
|
Heavy Duty |

Camper Trailer Pack |
4 at 6-30 psi and
2 at 15-55 psi (code SCV5/HD) |
Light Duty - 0-10 psi (code SCVLD)
This deflator has been designed for those who require lower pressure ranges with
extreme
accuracy. Suitable for competitive Rock Crawlers & Dune Buggies who deflate to
as low as 4 - 5
psi with bead locks.
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.
Standard - 6-30 psi (code 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 7 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.
Heavy Duty - 15-55 psi (code SCVHD)
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 8psi 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.
Camper Trailer Pack - 4 at 6-30 psi and 2 at 15-55 psi
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.
How to Deflate:
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!

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 through 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 from the finger grip located at
the base of the valve. 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.
