This is an update to our video How To Inflate High Pressure RV Tires. If you haven’t already seen it, this one won’t make sense. You can watch it here:

How To Inflate High Pressure RV Tires

UPDATE! If you want to avoid the time and effort of assembling a system like this, check out the new way we inflate our tires:

Inflating RV Tires the Easy Way

After using our air compressor setup for nearly a year, we wanted to improve it a bit. The way it’s been, it required 2 people – one to add air to the tires, and one to pump the brakes when needed.

If you’ve watched our original video, you’ve seen that adding air to high pressure tires from the RV’s on-board compressor can be trickier than you’d think. Since a diesel RV’s air system cycles up and down between about 90 and 120 PSI, it can actually remove air from your tires when the system is on the lower end of that range.

When the pressure is on its downward cycle, the only way to get the compressor to restart is to reduce the pressure far enough. We used to have to pump the brake pedal to accomplish that. Now, with our modified setup, one person can reduce the pressure right from the air chuck. Check out the simple modification we made to see how we did it. Just two inexpensive parts added into the system did the trick.

      Hi Duane. I’m sorry, but it’s been so long since we created this system that I can’t remember the exact parts I used. Also, we haven’t use this method in the past couple of years, having switched instead to an improved method, which we outlined in a follow-up video. That does require a considerably more expensive purchase, but if you’d like to see it, you can check it out here.

      If the Viair compressor is more than you want to spend, freezing the frame in the above video during the close-ups, you can see how we pieced it together with parts that mostly came from the plumbing department at a home improvement center.

  1. For those disinclined to assemble their own tire pressure filling system from parts, your favored manufacturer makes an equivalent assembled product with either a digital or an analog gauge. No gate valve is needed because an air release button is built into the air gun body.

    Other manufacturers offer both a straight or a 90 degree locking valve clamp and usually for considerably fewer dineros.

    1. Hi Steve. I’m sorry, but it’s been so long since we created this system that I can’t remember the exact parts I used, and we’re away from the RV visiting family for the next couple of months, so I can’t even check the set-up to see if I can get details on them. I’ll try to inspect the set-up when we get back to the RV to see if there are markings on the fittings that I can list for you. If you don’t want to wait that long, if you watch both the videos and freeze frame during the close-ups, you can see how we pieced it together with parts that mostly came from the plumbing department at a home improvement center. If you haven’t already assembled something by mid-July (when we’ll be back at the RV), drop me a note and I’ll see what info I can pull off the parts.
