Tire Deflator Options

Can’t seem to find reliable info on TW covering all the options out there for deflating tires. Hopefully folks who know their stuff can chime in.

I currently use an ARB E-Z Deflator knockoff, but I’d like something I can leave on the valve and set and forget at the trailhead.

Someone in the DFW forum posted this new concept, but why stop there? For $120 it should provide a kinetic-powered bluetooth actuator so I can press a button on my phone and all 4 tires will drop to my preset PSI.

Will this do?

 

$6, don't over complicate this, all 4 tires in 1 minute.

 

i use some cheap staun knockoffs from Amazon and they work great. takes some fiddling to get them set to whatever pressure you want but is consistent once i set them good.
plus they came in a 6 pack so i have 4 set for most trails and then 2 set for super low for super slow stuff

 

Just don't buy the Smittybilt valve deflators. They're unbelievably inaccurate when set accordingly.

 

Trailhead deflators have worked for me for years reliably. Can get them at Walmart too. Takes time to set up but worth the time.

I've been running these for about 15 years now with no issues. I like them because you can check the psi with them on and do multiple tires at once.

Same.

I've got similar stauns knockoffs. They work great. They're slow, but yo just stick them on and walk away.

Use that time to pound your trails beers (kidding) or whip out the map and discuss the route. Technically you could drive with them on, but I don't see a reason to do that. It increases the chances of ripping a valve out, too.

I set them at 18 psi. If I need to go lower, I just do it the old fashioned way with a stick or a small rock, lol.

 

I have a knock off set as well and they SUCK. I've tried to set them multiple times and they are still extremely inconsistent. Seems like YMMV with these knock offs.

 

I don't, and won't, run auto deflators so have no personal experience but people I trust who are very experienced claim Coyote is the way to go. They claim they are somehow better than Staun.

This, though. Been airing down with ole reliable for the last 10 years. Way faster than my buddies fancy dancy deflators and octopus hose setups

 

Another cheap version...

Long ago I went to the hardware store and auto parts store for an air chuck, gauge, radiator drain petcock and a few brass pipe fittings. In about ten minutes I had a quick deflator that’s now over thirty years old.

I wonder how much it would cost today. Still much less than what’s offered today I’d bet.

 

I've got Coyote deflators and love them. Solid design, American made. Pretty quick too. When I first got them I checked the setpoints and they were all nailing my requested 18 psi setpoint over and over. I changed it around myself and they give repeatable results without loosening.

IIRC the differences between Coyote and Staun are faster deflation, wrench flats to snug up your settings, come with a second pack of springs to cover high and low pressure settings instead of buying another model Staun, and I believe Coyote also OKs screwing them on at the trailhead and taking off, removing them at the first opportunity (just be mindful you've got chunks of brass hanging off your valve stems).

 

I got these, they work OK. I haven't used any of the other brands, but one thing to know is that they use a spring that is actuated by the tire pressure. So let's say that you set the deflators to 10 PSI, once the tire gets low on pressure, the air is released at a much slower rate until it gets to the 10 PSI. This is fine for me, just something to be mindful of before purchasing. What I did was set my deflators to about 7 PSI, that way the spring is easier to push and deflate quicker to 10'ish PSI. I put each one on, and by the time I get the 4th deflator on I am ready to remove the first installed deflator. Highly recommend

 

Stauns

 

Wow that's quite the price tag
