Airing Down

I'm looking to grab some automatic tire deflators, anyone have any recommendations?

It will ultimately depend on your current wheels. Some aftermarket wheels will have less accessibility due to placement of valve stem.

Universal ones like teraflex will work with all valve stems, but if your valve stem has ease of access, there are valve core removal deflators like staun, and arb.

I have used both the Staun Deflators and the ARB E-Z Deflator.

If "automatic" is what you want, the Stauns very popular and very easy to use once you've calibrated them. They come in a pack of 4, just screw them on the tires and wait until they automatically shut off at the PSI that you've calibrated them for. They're really great, that is until they eventually get dirty or corroded, and then they no longer stop at the desired PSI, and you end up having to air back up to the desired PSI. I've tried opening them up and cleaning them, but they never get back to new, and become unreliable. At that point, either replace them, or move onto something else, which is what I did.

I now use the ARB, and have been so for about the past 5 years or so. It's not automatic, but it's more reliable. You can only do one tire at a time, but they deflate much faster than the Stauns, so in the end it takes about the same amount of time. You have to screw it onto each tire one at a time. It removes the valve core, allowing the air to come out much faster. Use the attached pressure gauge, which is quite accurate and reliable/durable, and manually stop at the desired PSI. My first one eventually got dirty or corroded and difficult to use after 2 or 3 years, but when I contacted ARB for advice, they immediately sent me a brand new one. Great customer service.

Reason not to manually air down?

Hi, sorry to go off on a tangent, but anyway . . . ..

I'm a brand new Jeep owner, I've just signed up for a Jeep Jamboree, excited to try out the capabilities. I don't know of anywhere locally to drive off-road so this may be like a once-a-year thing for me.
I was planning (for airing down at the Jamboree) to just let air out a bit at a time manually and keep measuring with a tire gauge (or the one in the dash menu, but not sure how real-time that is).

Any reason not to do this manually, is it just a convenience thing for those of you who probably air down and up a lot more often?

Thanks.

This is what I do, I only off-road a few times a year and didn't feel the need to spend the extra money. A relatively cheep 12v compressor from Menards and a $1.49 tire gauge. Suits my needs fine

I bought the Curry deflator a week ago or so.
I tried it out over the weekend, it works great but I was surprised how long it takes to drop 15 psi off a big tire.
I guess I'm used to mountain bike tires:).
I am happy with the deflator though, nice to have the built-in gauge.
