The problem isn't with the tire or it's air pressure. As I mentioned in your other thread, the chains need to be shortened.I have a problem when I put the chains on the back tires after I put on the tightner.
I'm thinking it pulls the chain to tight or the tire needs more air.

Before you cut anything, you need to fix whatever is going on here. Your cam is on all wrong and appears to be held together with some sort of twisted wire?OK how do I shorten the chain? What end do I start at.
The hook that you have the wire on is installed wrong. That hook is the "cam". It's supposed to go completely through the last link in the chain and hook back onto the chain. You really need to watch some of those videos carefully. This is something that is better explained visually. New chains aren't going to help if they're installed incorrectly like the current ones are.The twisted wire is to keep the chains they do damage when they come off.
I wish I had cams on the chains you turn up and hook into a link. In the Spring I will buy new chains for the tire size.
14.9-28's should be good at 12-20 psi depending upon the load being carried.
Being liquid filled …
Shouldn't12psi with liquid filled is asking for leaks around the bead imo
Or even worse the bead unseating loosing your fluid.
