Airing up tires with compressor

Will this work?
Amazon extender
Could be awkward screwing it on the inner tire, impossible on the outer.

It's been maybe 15 years but I've found 12 volt compressors that you can set the turn off pressure, and walk away while the tire is filling, and go back when it turns off.
I've used and it works.

If you have Tire Man or Borg or other long solid metal custom formed valve bodies installed on all of your wheels it will be quick and easy to add or adjust air pressure with any kind of air chuck and beauty disks in place. As said above, it takes some time and technique to fill a tire to 80 psi with a 120lb rated compressor. Let the pressure build up to over 100 psi before attempting to add air. Gas station air hoses are often not able to fill RV tires to 80 psi or are set for car tires at 32 psi. Many of us use 65 psi in front tires and 75psi in the rear duals.

That straight-on dual-foot chuck is what we need for RV use, either air chuck or air gauge, if we are not using custom valves or extenders. The ones where both feet are angled don't connect all that well. The foot is also bigger, making it harder to get past some wheel simulator holes.

Harbor Fright offers this little air chuck that snaps in place. Needless to say the valve stem has to be where you can reach it. I love those things but:

1. Don't use it on Bike Tires! Slow getting it off and you'll blow the tire.

2. Sometimes the wheel covers on cars prevent getting it in place

So have an alternate chuck in your stuff.

With tools like that long air chuck and a corresponding air gauge, you CAN check and air your tires without extenders (which I don't recommend) or custom valves (which I heartily recommend). Ordinary 2-inch METAL valves, with Air-Through Caps (see V2B, Gator, Crododile, Amazon and NAPA have them), you can get right in there and do your thing. I just wanted to be able to do ours anywhere, anytime, with anything that was on the end of the air hose.

I have similar to this...clips on - then no hands inflation except to push the button..

Available any auto parts outfit, Walmart, etc, or on line.

I have a clip on with a gauge built in. It is hard to get to 80 lbs on a 120 lb compressor.

Something like this. Stays on by itself when filling. Bend over stick on, watch gauge on tank, pull off when aired up. I think I have a smaller one about 8 or 10 inches long, not 14 inch that link shows.

I gotta ask:
Under what conditions do you think you will need to air up a tire all the way from ZERO PSI while out on the road ??

It looks like this won't display images in the .tiff format. I'm working on it. The question remains, just without illustrations.
