Trail tire repair kit and Staun deflaters

I've used this ARB deflator for a few years and have been happy with it. It's not automatic or anything, so you have to manually use it. It's pretty quick, a lot quicker than what I was previously doing, pushing the valve core in with a pointy rock. 😀

It was only $40 though when got it.

I used the Currie/ARB Deflater for many years before switching to Coyote deflaters. I much prefer using the Coyotes.

That is a great idea - I’ve ordered a set to try out.

I use the Stauns, and they work well and stay accurate for me. Mine are set at 10, and when I use them they always wind up within a half pound or so at worst. I have never had one stick and under inflate. But the trick I have found is that they have to be maintained - specifically they have to be clean. Dirt or debris impact their function. So once every year or two I pull them apart, clean and lightly lube them with silicone spray, and recalibrate. For me, the time savings during air down is worth the effort.

All that said, depending where I wheel I am generally going less than 10. So I use the Stauns to get to 10, and then use a digital Powertank air chuck to drop the rest of the way.

Why 2-step it instead of just pulling the core?

That's what I use, though mine says Currie on it. Same exact deflator, it really works well. And it's FAST!

Mine would only vary by a couple of pounds. 4psi would be pretty damn obvious even to a newbie! There has to be some operator responsibility while operating these beyond the norm. Just sayin!

Of course it’s obvious.
That’s not the point. If I have to monitor the ultimate psi for a preset deflator then a deflator that has a preset is pretty much useless.

How do you mean? Just yanking the core - and get to a pressure how? Or do you mean using somwthing like the ARB?

Yeah you have to use a gauge. I bet it's quicker than what you're currently doing. And easier as your auto-deflators aren't good enough to trust, basically negating all benefit.

Listen to the air coming out when you pull the stem and you can tell when it's getting close to target pressure once you've done a tire or two.

I get the value of auto -deflators if you don't have to watch pressure manually. If you still have to end up doing that I'd rather not use them at all.

No, I don’t have to use a gauge. As I said they drop to 10 consistently, and I do trust that they do so. That’s what I wheel at unless I’m doing something crazy - that’s when I get out the gauge to quickly drop the last few pounds.

Quicker and how much time I spend doing it are two different things. With the deflators I spend about 1 minute putting them all on, and then do something else until all four are done - and I can the take them off at my convenience.

I have an ARB pull the core deflator as well. It is a lot faster than the Stauns - but you have to stand there the entire time. I spend much, much more time actually doing it that way.

But the fastest ever was when I ran Powertank monster valves on my old Spyder Locks. They were crazy fast to deflate and inflate.

Been using Shaun Deflators and a Longacre Tire Presure gauge with built in deflator valve for a long time. Keeps my friends from seeing my Buttcrack for extended periods when I was using a Currier Deflator.

Wonder what people would say if Rough County was the only one that made a Core style Deflator

I can trust my daughter (9) to deflate with my coyotes, I don’t trust her with my ARB deflater. Something to be said about simplicity. Mine are all consistent also.

On @Mr. Bills recommendation, I picked up a set of the Chuck Mates (the $30 version) from Amazon to give them a try.

So I pulled out my Stauns, and screwed on the clips:

IMG_7298.JPG


At which point I remembered that I had lost one at the trailhead for Pritchett back in the Spring - more on that later... :rolleyes:

They are definitely easier and faster to install compared to screwing on the Stauns, the clip is very solid, secure, and leak free. So on that point the Chuck Mates delivered.

Since it is roasting outside already this morning, I though a quick side by side comparison in the A/C would be a nice diversion...

IMG_7301.JPG


So I verified my front and rear pressures to be 25psi, threw a regular Staun on the front, a Staun with the clip on the back, set them both off and hit the stopwatch.

My first observation was that to my ear the regular Staun (first in this clip) sounded like it was flowing more air than the clipped version in the rear:



Sure enough the regular Staun clicked off first - at 8:32. And here is the pressure (recall that I have my Stauns calibrated to 10 psi):

IMG_7302.JPG


The clipped Staun completed at 10:27 - taking just about 2 minutes longer. And this was the pressure:

IMG_7303.JPG


A pound high. As I said previously, unusual for it to be off that far. I pulled the pin on the Staun to make sure it had just not clicked off early for some reason, but it immediately shut down again.

To test if I had a problem with that particular Staun, I pulled the clip and repeated the test using the same deflator. It completed in 8:23, and here was the pressure:

IMG_7304.JPG


Back to normal.

So, with the clips the Stauns are significantly slower (almost 25%), and the pressure is off. I can't understand the pressure being off, but perhaps the lower volume flow allowed it to click off earlier? No idea. Perhaps if I recalibrated the Stauns with the clips installed it would correct the issue - but to drop another pound at that flow rate would also increase the deflation time.

So they are going back (since these were the $30 version, not worth keeping). Yes, easier and quicker to install, but only marginally so, and not worth the time and accuracy penalties.

But now I need to solve my original problem - I'm down to three deflators. I've heard a couple of folks recommending the new Coyote's, and even through I'm quite happy with the Stauns, I may order a set of the Coyote's and give them a try.

Oh, and yes I had time to do this on a Tuesday morning. What dafuk have I done with my life....:oops:

Thanks for testing that. I've had those exact clips in my cart on Amazon for a long time as I'd seen Mr. Bills mention them before. I'd hate to slow down my airing down anymore. I'll remove them from my cart.

However, I can't recall when I've had anybody else waiting on me to air down so I'm less concerned about air down time than I am air down time.

I use the auto deflators as well, I bring them into work to calibrate the pressure releif with a large pressure tank set to 10 PSI. The biggest take I see, is how you screw them on/off... don't screw them on using any of the moving parts, use the barrel that attaches directly to the valve, and they should stay in calibration for a long time.

I have used Stauns for many years and noticed within the last couple of years they have not been consistent in lowering the pressure. As a result, I went to my ARB deflator. I like your idea of basically giving them a little maintenance. I'm going to try that and see if I can get them all back to being consistent.

@NashvilleTJ

Thanks for running that test.

I expected that it would take a bit longer to hit the target pressure with clip-on chucks attached to my Coyote deflators, and that was my impression when I used them, but I never timed the process. I've never been in enough of a hurry for it to matter. The purpose was convenience rather than speed.

I haven't had any issue with accuracy. I do not recall that the chucks changed the target cut-off pressure, only that the valves still closed at the same pressure consistently. Since it is my practice to check and equalize any differences in tire pressures a few minutes later regardless of the deflation tool, it hasn't been an issue. In any event, I think those versed in "best practices" would agree that recalibration should be expected when an appliance such as an automatic deflator is modified.

I can't believe that Chuck Mate is getting $30 for a set. I paid $20 or so and thought that was robbery. The cheaper option I linked earlier in this thread looks like the same product. They are also available from McMaster-Carr.

I will forward the link to your test to Harry Lewellyn at Coyote Enterprises. He will be interested. I spoke to him about the Chuck Mates before I ordered mine. He couldn't think of a reason not to use them with Coyote deflators and asked me to send him my impressions. I'll send him yours as well.

BTW, I have two sets of Coyote deflators - the original version without clip-on chucks that I keep in my Jeep and the new Vortex version with the Chuck Mates that I keep in my Sprinter, set for different pressures for the front and rear axles.

Regardless of brand, brass automatic deflators must be periodically cleaned and maintained.


Here are the cleaning and maintenance instructions for Coyote deflators:

I just dropped on to Amazon and searched for the Stauns. 99 bills! I don't recall them being that high when I last picked them up - but that has certainly been a while.
