Don't know for sure, but that tire looks like a 315/70R17 BFGoodrich KO2, with a load rating of 2,915 lbs. and a max pressure rating of 65psi... Don't know for sure what specific year your Toyota is, but looking it up online - a new Toyota Tacoma SR weighs 3,915. If you take 3,915 pounds and divide it by 4 (tires) it averages out to 978.75 each tire has to support - statically. If you take 2,915 pounds and divide it by 65psi - That's 44.85 pounds of support for each '1' psi air pressure. Then take that 978.75 required weight support and divide it by 44.85, to get a 22psi per tire MINIMUM air pressure to support your vehicle statically. Now take into account that while driving, even off-road on rough trails - While you may be driving at slower than freeway speeds, your vehicle will transfer MORE THAN 978.75 pounds on any particular tire(s) as you drive through, accelerate, brake and/or stop going through turns. With all THAT said - Airing YOUR tires down below 22psi while offroading can lead to premature wear on the low-end of the anxiety technicolor dreamscape to tire failure on the high-end of the WTF Was I Thinking Trouble Code. As an aside - I respect that you went to the trouble to install a quick-disconnect on all four corners and use short hoses instead of a ridiculous rat's nest of 20 foot lines - - AND that your tires are actually MORE than twice the height of your rim's diameter. (I 'HATE' those Brodozers. Those Pavement Princesses. Those Wannabe Mud-Terrains... It's the smell, if there is such a thing. I feel saturated by it. I can taste thier stink and every time I do, I fear that I've somehow been infected by it. It's repulsive, isn't it?) The only OTHER thing(s) I might suggest is that you purchase or fabricate a set of dust/dirt/mud cap for those Female Quick-Disconnects you have in each fenderwell - -And that ARB compressor, while being water-resistant is not water-proof.
Interesting point. Weight distribution is not 50/50, but I think I get what you saying. I go down to 12 psi in the rear; my rear is very light. The tires are E-rated too, so they aren't deforming much at 12 psi. I spent my whole afternoon thinking about why max load rating of a tire divided by max psi would yield lbs 1 psi can support. Can you elaborate on why this is? I'll certainly continue to think about it and get back with you.
@@jdesigns7239i mean CTIS, i have similer system like yours i just need the rotray or hub (installed on wheels) in order to inflate or deflate while driving check please the footage at 12:29
@@Saleh900 That’s a video of a semi. I have no idea where to find hubs like those. I know there is a company making add on CTIS like that, for the 4x4 industry; tho I don’t recall the name.
@12:11 in the video I show a system diagram. To deflate you would add a dump valve by the interior gauge. I use Apex tire deflators each tire individually is like 10 seconds so it is a fairly painless process and so didn’t see the point to adding deflate abilities to the system.
No, but @12:11 in the video I show a diagram of the system. Draw yourself a diagram to help work out what fittings you'll need. I used 3/8" air hose with push connect fittings; I'd try to stay away from NPT fittings where possible bc they're expensive and more prone to leak. Use bulkhead fittings to mount through things.

Do u know where to find wheel rotary or hub to inflate or deflate ?
Im not sure what your asking. Whats a wheel rotary.

Very cool, I am looking to do the same but also want it to deflate all 4...can you do that?

desicant air dryer.
great content!
Where did you get the rubber covers for the air couplers
Amazon; its called a 'coupling dust cap'
Did you use 3/8 O.D. air line?
correct
How are you do you have a parts list yo can show share with us.
No, but @12:11 in the video I show a diagram of the system.

You need to buy my Marine Corp trailer, camper m353? Pretty sure.
But I'm already building a camper lol.
You don't want it?
Your camper would fit inside it. I’ve had my fun with it. A marine built the hitch you won’t believe it
How can I send you photo?

Bitchen setup, great content !
