do you supply air to your trailer before pre-triping it?

    if not you should. you won't know if you have an air leak if you don't
    it seems like every time i forget to push in the trlr supply before PTI i end up with a trlr with an air leak. this time it is coming from where the auto-inflate comes out of the hub!!

    Always, and with air suspension, you need to make sure it airs up as well.

    I try to make sure I always do this, but I have forgotten on an occasion or two.

    As I recall, all brakes are supposed to be released to do a proper PTI aren't they?

    Mind you I don't think I've ever chocked the wheels and crawled under the truck like is done during a level 1 DOT inspection, but that's what the law says we're supposed to do.

    If y'all don't supply air to the trailer BEFORE pre-trippin' it,
    you should DURING pre-trippin' it. :yes2557:

    If y'all supply air to the trailer AFTER pre-trippin' it,
    y'all didn't do a proper pre-trip. :biggrin_25512:

    25(2)+2 is correct about air-suspension/air-ride.
    If there's a problem with the leveler valve, y'all need to
    know that right away.
    If it's not workin' correctly, your trailer will be a-leanin'
    to one side. And that'll get'cha an out-of-service.

    And don't forget to DRAIN THE CONDENSATION outta
    the air tank(s).

    My trailer is always aired up. I generally do not pull the red knob unless I need to drop my trailer.
