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.
