This is a picture of a tight turn with the wheels cocked under pressure, all of us do it but usually don't see the wheels.
I try to 'unload' the tires when I turn, backing up and then turning again. I did this for the picture.
Monday, Sue and I have to jack up the trailer and pull two wheels, take them to the tire shop and get the new ones changed, then the other side of the trailer. There is a strip joint across the street, I think I will let her pull the wheels while I have a couple of cold ones...
