    Airing down tires for traction is an old trick that is used by many looking to gain traction. Airing down each tire on its own, and then airing it back up can be faster with a 4 way setup.

    I recently made this setup based on the following video.



    with a slight change, I made the Gauge and airport assembly removable so that it would be easier to protect the digital pressure gauge. Not shown is the 2 extra male threaded barbed adapter or the hose clamps. and quick release chuck and extra fitting

    updated parts list from video decription

    50’ 3/8 air hose http://amzn.to/2tCWsek

    Cut into 7 pieces

    2: 12’
    2: 8’
    2: 3’
    1: Leftover section

    4: standard bore lock-on air chucks http://amzn.to/2tCZShe
    3: 3/8” T hose fitting http://amzn.to/2tx0xQN
    1: ¼” brass shut off ball valve http://amzn.to/2seaQ8D
    1: ¼” brass barstock female T http://amzn.to/2seuP77
    1: Pressure gauge with 1/4” fitting http://amzn.to/2tz3WxZ
    5: 3/8” barb with ¼” female fitting http://amzn.to/2szLVvu
    15: ¼” to 5/8” hose clamps http://amzn.to/2txf7HZ
    2 : ¼” Female NPT Plug http://amzn.to/2seaI99
    1: 1/4-Inch Universal Brass Coupler with 1/4-Inch Female NPT

    and the extra cut to desired length for you gauge and fill assemble


    Start by threading the locking tire chuck on to the ends of the two 12 foot hose section, I mocked everything up with out teflon tape first.

    20181227_194018.jpg
    On one end of the 3 foot hose, push in your barbed 1/4" male fitting and secure with a hose clamp, and then attach a locking tire chuck.

    20181227_194922.jpg

    20181227_195044.jpg

    Attach the the 12 foot hose to the base of the barbed T as shown above, and the 3 foot hose to the leg of the T as shown .
    20181227_195751.jpg

    attached the 8 foot length to the other end of the barbed T fitting.


    Now repeat with the the remaining 12 foot, 3 foot, and 8 foot piece to make 2 of these assemblies.

    20181227_195959.jpg

    Join the left and right side hose assemblies together with your left over Barbed T.

    I then took the left over hose section cut it in half. and added to the T

    At the other end I added the 4th barbed 1/4" male adapter

    20190106_145337.jpg and a Male quick release air fitting

    This completes the heart of your 4 way Inflate / Deflate system, The Brains of the system is up next.
    the control valve, gauge and air fill /discharge port.

    20181227_200615.jpg

    assemble as shown above and tighten all connections to ensure a airtight seal.

    20181227_205016.jpg


    add your pressure gauge, and your 5th 1/4" male threaded barbed adapter, and your quick release air chuck. Line the face of your gauge up so you can read it while using the valve.


    20190101_162443.jpg

    before attaching to your tires you will want to make sure the valve is in the off position or you will start to loose air right away. 20190101_162507.jpg

    20190101_162520.jpg

    20190101_162641.jpg

    lay out your hoses and attach to your valve stems..

    20190101_162720.jpg

    When turn you gauge on and set to PSI, press and release to change settings. press and hold to turn off.
    Open the valve and watch your pressure drop. once you reach the desired pressure close the valve, turn the gauge off. and remove the tire chucks.

    To inflate just add your air source to the airport before you open the valve.

    Super cool! I’ve been thinking about doing this since I saw that other video. Thanks for the write up.

    (Yes I deleted my question)

    I made one too after seeing that. Mine is a little different but it works in a similar fashion.

    That's pretty slick.

    Though, one would have to assume your compressor would need to be up to the task of filling all 4 at the same time?

    The compressor puts out a given CFM. Whether it goes 1 tire or 4 at same time does not change the overall CFM. The bigger benefit in time is airing down, as you can air down 4 times faster.

    How long does it take to air up on that compressor? It's the single version right? I like the idea of it since it costs a little less and is smaller.

    Thanks!

    Any decent compressor will work.

    It takes the same amount of time to inflate all 4 as it takes to inflate 4 individually. It is the same volume to air up. I did not time it but I estimate the inflation time of my four 315s from 17 to 32 psi takes about 7-8 minutes with my arb single.
    The biggest advantage is that I do not have to crunch down to deflate/inflate each tire so I just light up a cig and ignore other people's groans and envy. Hahahha. Also, deflate/inflate leaves me with perfect psi match in all 4 tires.
    Yep, the single arb works great.

    Whooo! Those bore-lock chucks are pricey! That said, i want need them and added them to my shopping list. Thanks for the write-up, my system needs a bit of a refresh and this is just the motivation I needed!

    I have a chuck on the front and rear bumper, and have two hose assemblies but a very similar reason for doing this - envy of others ! :tonguewink:

    The place is called Princess Auto, here in Canada. But you can find all the parts on Amazon.
    You need the "normally closed" chucks.

    Everyone runs matched tire pressures front and rear? I typically adjust for load just a bit. I guess a two tire setup may be better for me.
