Back rear tires are wobbly due to uneven air in
Be ready, this is a little bit of a dirty job, have rags handy..
What you need to do is coax the tube back inside the tire, without damaging it. Use hands only, no screwdrivers or other tools.
Sometimes letting all of the air out helps, some air back in helps...but you need to wind up with the tube fully inside the tire and NOT at all in the tire bead to rim area. This is where the add air helps...
When you achieve the above steps, you need to ensure that the tire bead (the part that actually touches the wheel) is even and seated all the way around. INSIDE and OUT... Then add air and often check that the tire bead is still correctly located inside the wheel. (What happens is the bead goes deep into the rim on one side, and that allows the tire to go clear past the wheel on the other side...Just center everything..)
Then blow the tire up to the correct pressure. I think you want to be a little on the high side, as the tires need to be able to roll with low resistance, and that takes pressure.
I hope this helps. Check all of the other tires for issues and pressure and cruise on.
