Tyre Deflators

NachaLuva · Post by **NachaLuva** » Sat Jan 14, 2012 4:19 pm

I just bought a set of tyre deflators similar to the Staun brand:
http://www.ebay.com.au/itm/220879431...84.m1439.l2649

Seem good enough but as with them all only go up to 30PSI

Then today I found these:
http://www.ebay.com.au/itm/290654480...84.m1423.l2649

They go up to 40PSI so I could have one set to 36PSI so at the end of a trip when I air back up I could air up to say 40 then using the deflator go down to 36PSI (36 hot = ~34 cold). Accurate, quick & easy

What do others think?

I can't help with your question but wouldn't it be best to just air up then check with a pressure gauge to find you 34psi?

I have the exact same set of tyre deflators but mine were $7 on ebay. I jsut don't know how to set them. I usually go too low with 1 tyre and have to pump it up. haha
They are quick at going from mid 30's to 15 ish. By the time all 4 are screwed on the first one is almost done.

the onyl use ive found with these sort of things is that its not using a stick (that usually breaks inside the valve stem) and gauge etc

id say keep the 40s on all the time

meanwhile, what we really need is an auto tire de/re flating system to be used while the vehicle is moving =D

Sounds like you want to turn a single step job into a two-step job. And deflators aren't very accurate. I have a set identical to that in your first link and if i calibrate all four deflators off the same tyre, they're lucky to get the other three tyres within 2 psi.

Whatever tickles your bits.

I have just one set (of 4) and use 2 of them at 20PSI and the other 2 at 12PSI (just need to make sure you mark them so) and use the tyre gauge on the compressor when inflating.. you can get away with a few PSI difference, as long as you check them at the next service station tank fill.

+1. Controllable from inside the cabin

Thanks Dane. for my purpose they don't need to be accurate. I will set one to say 15PSI, another to 20, another 25, last one to 36PSI.
So if I want to air down to 20PSI I pull out that one deflator & use it on all four tyres. It wont really matter if it airs them all down to 14 or 16PSI as long as they're all the same.

When airing up you still need to air up past the desired pressure & back down with an accurate gauge. The gauges on compressors are so inaccurate plus they're analogue.

It just saves having to fiddle around with manual deflating, then checking, then deflating some more, etc. it makes it easier. see above

$7!!! Damn!

I'll try to find instructions for setting them

Lol

Instructions as promised:

How to Use
1. Deflate a tyre to your preferred deflation pressure. eg 20psi
2. With the locking ring and adjusting cap wound down, screw your tyre deflator on the valve stem making sure it is clean and the thread is in good condition.
3. Loosen the cap (anti-clockwise) until deflator pops open, then immediately tighten cap to the position where air stops exhausting.
4. Turn lock ring up to adjust cap and tighten.
Your tyre deflator is now set to your preferred deflation pressure. Adjustments to your deflators can be made at the rate of 3 PSI er half turn of the adjusting cap.
Once the tyre deflator is set to your desired psi (20psi) it will automatically shut off and stop releasing air out.

Like the hummer's did.
You could inflate/deflate and check temperatures of all 4 tyres from the cab.
That would be cool.

I bought a cheap knock off set of stauns...
Very dissappointed.
I've set them all, but they end up at different pressures, they are never consistant, even after resseting and double checking, and arent that quick anyway?
I can almost do it quicker with One good quality gauge doing one tire at a time than what all 4 of the cheapies do, so i'm quite annoyed with my 25 dollars

But I've seen the genuine ones in action and they seemed far quicker and more accurate, so one day i'll spend the money,

As for setting them to 36PSI to reset your tires after inflation, get a compressor with a more accurate gauge?
the gauge on my compressor is accurate so i know mine are always set right?

If i'd paid $7 i may not have been so dissappointed.....

I still like my cheap option of finding a stick

But a set of deflators setup with each one at a different PSI setting sounds like the go.

I've also found my portable compressor's gauge to be quite accurate

Cheers

Just went out & set them. Was easy peasy to set!

But I found they dont deflate very well...cheap eBay knockoffs

Oh well. I can either get another type which may work better ($50), or get the genuine straun ($60-$100) or I could just put up with em. Or go back to my stick!
