Tire pressure / dually / TC
RAM 3500 dually that will soon have a TC on it. It's a question of what should the rear tire pressure be and I'm wondering what you run your dually at. The camper should be around 4-5k pounds. I'm ...

I don’t have a TPMS, it was an option at the time of purchase, but the original owner decided not to have it.

Without a TPMS, most of this conversation doesn’t apply to me. Plus I have been away for a little bit.
I’m just as confused as when I started. However, buying a crossfire with a little less pressure does seem to make sense. I just don’t know if I should get 65, 70, 75, or 80psi.
I’m leaning towards 70psi cold.
I’m also concerned that Kaytag1 had a slow leak and the crossfire didn’t isolate the bad tire. If I recall on a slow leak it should isolate at 5psi drop and a quick drop at 10psi.
On the other hand this is the first I’m hearing of the crossfire failing.
I can’t thank you all enough for responding. Thanks for your time and expressing your experiences.
In short, if you have 5000lbs in back air them up to 75-80psi. 4000 lbs 65 or so should do it, but erring on the high side loaded down will not hurt a thing.
I think the inside tire hotter thing is a sales pitch. Maybe briefly on a hot day on a big downhill, but the few psi won't make a difference. That's bunk.
Good luck with the new rig!
