    At the end of the day, it really boils down to the output of the compressor. All the tanks are just temporary air...

    If you are indeed going with aev flares, you pretty much need 40’s. Anything else just will look odd as hell.


    I kinda remember seeing a pic of a set of 37’s with the aev flares and no lift. Still looked roller-skate ish.

    Yes CFM is important and why I chose the same unit. But on my little 35s, it took 8mins per tire coming from 20 to 60psi without the tanks and 3 minutes with the tanks. That is 20 minutes, not a deal breaker, no, but something to consider if it is 7-9 minutes per tire with 40” tires then you will be airing up for 30-40 minutes.
    If I leave my compressor off, the tanks can almost do 2 tires 15lbs when full. If space would allow, I wanted to run bigger and longer tanks on the frame, but I could not get them to fit just right.

    Am messing up the OPs build thread so we can revert to the On board air thread I had last year if need be.

    Ahhhh, so the amount in the tanks is actually filling nearly two tires....that must be why it takes less time with tanks. Definitely worth it for the time savings i suppose. Shit, might as well add a few more tanks hahahahah.

    The problem with your thinking is that proper inflation pressures change with tire size and there would never be a reason to run 60 psi unless you were max towing.

    Stock: https://tirepressure.com/lt285-70r17-tire-pressure

    39" KM3: https://tirepressure.com/39x13-50r17-tire-pressure

    40's: https://tirepressure.com/40x14-50r17-tire-pressure

    For example, if your vehicle was distributing 2755 lbs per corner:

    Stock tire = 50psi
    39" KM3 = 29 psi (30 psi for 2855, so I'm guessing)
    40's = 25 psi

    problem with my “thinking”??
    I run 52 lbs daily as I carry 600lbs in gear and mods.(check out my build thread. Watch out you might learn something;) ) I air up to 60 when towing. That day I am referring to, I was only testing and running a stop watch. This is my 3rd truck with on board air and I learned as I went. Though it is not my first rodeo neither, there is still plenty to learn from this forum.

    Yep, a big problem. You don't understand how tire inflation tables work. It's science, not some dark art. The drivel spewing from your fingers would be comical if people didn't listen to you and follow suit.
