Air Compressor/Inflator for the 4Runner

I'm using this Smitttbilt deflator:

Smittybilt 2823 Rapid Tire Deflator (R.A.D.)

$35 SmittyBilt R.A.D RAPID AIR DEFLATOR - SB2823

https://www.amazon.com/dp/B06WP6R917

It works well, but it's more work than the automatic type mentioned above. The one benefit I see is that I can put the tires at whatever pressure I like for the situation.




This style is very popular, as you just set them up and then screw them on to deflate.

Staun Automatic Tire Deflators (Standard Duty 6-30 PSI)

$100 Staun Tyre Deflators | The Australian Original Tire Deflator | Automatically Airdown Tires to 6-30 PSI

The downside being that you're stuck with whatever PSI you set them at. One smart Idea I read was to set 2 up for a typical easy trail pressure (maybe 25-ish PSI with stock size tires), and set 2 up for a lower pressure for more difficult terrain and maximum flotation.

 

I use this Viair Tire Deflator. It's not as fast as an Arb style that removes the valve stem but I feel a little more in control with it.

It's a little finicky but does the job.

I had previously bought a generic Chinese Arb style (Arb is also made in China) deflator off of Amazon. It was garbage. Didn't work.

 

I use the teraflex deflator, identical to the arb

 

This *is* a good idea. Gonna use it. Thanks.

 

You're welcome!

Do you have a set of those style deflators? Just curious which brand and how you like them?

 

Thank you for the deflator suggestions! I really appreciate the variety of solutions that you all are using. Now I'll go navel gaze on this for a bit, until after xmas when I can buy myself toys again!

 

Stan's? Staun's?

Well-machined.

Work great on the bench and in the driveway. Haven't tested them out in a dusty, dirty environment yet.

what mounting plate did you use

 

Has anyone experienced issues with reduced valve stem life due to frequent use of the ARB-style deflators? I wonder how many valve core removal/replacement cycles the valve stem threads cam take.

 

I think thread wear is a non issue. The valve cores have O-rings. I think the O-ring would be the point of failure. FWIW I keep a couple of spare valve cores with my spare fuses.

 

I had an ARB twin with an intermittent internal short. Sometimes it would work, sometimes not. ARB is not the be-all end-all.

 

I'm less concerned about going through a bunch of cores as I am about wrecking the threads on the valve stem side. Then I'd be stuck with not only the cost of a TPMS valve, but also mount and balance. It's probably too much of hypothetical question, since I don't expect a tire to go much beyond three years, but cross-threading a core just once could be unfortunate.

 

Yes, cross threading would be bad. I was answering your comment about removal/replacement cycles.
