Airing Down DRWs

Cant recall the person I talked to but im sure any of them there can help you. I think it was called a stv, "on the hose"...

Thanks for posting. Have never seen those extra valves before.
Do you have name of the person you spoke to?
I broke hose fitting years ago and have CF sitting in my garage since at the time single hose was not available.
Now with new dually I might try to work on those again.

Airing down and especially up can be annoying, so consider that for straight driving with 4WD you might not need it.
I tried that, while pulling 3000 lb Airstream and was OK on wetter sand close to water, but got stuck on turn in dry stuff.
I wonder how the airing down with crossfire works AISURFFISH ?
The manufacturer says the system have blow valves, that will close when the air goes away too quickly.

notice the additional 2 valves below




Mine were specially made there is a special valve right before the pressure sensor that allows you to air down the inner tire one at a time it's the same valve that you would install if you had electronic sensors that you needed to add on the valve stem..
I was able to speak with someone at the factory and they took care of it no extra charged for the additional valve or any of that really good people to deal with.

I air down the hose prior to the large round valve/sensor.. but I air up on the single middle valve stem

We have not had any issues rubbing..
You will need a way to air down and up the inner tire.. I use the cross fire system..
Search the motor home forums on hoses to connect to inner tire.

There was another similar thread on airing down not long back.

Consensus of opinion was touching not a major concern at the very slow speeds you'll be using on the beaches.

Rubbing for a short distance at very low speeds shouldn't cause a problem. I wouldn't make a habit of it but it's better than getting stuck.
