I always go back and undo the last thing I did when there is a problem like you have. that way you are not chasing your tail trying to figgure out just what the problem is. When you make too many changes at one time then you always have a problem trying to figgure out just where the problem may lie. Like Belair says what about your front brakes? Jack the car up and turn the wheels and if they don't spin with the same amount of ease then there could be a clue.

Trying to stop a pull to one side by adjusting air pressure differenly from side to side, is not the way to do it. A low tire will pull to one side, and they sometimes look full when they actually have only 12 lbs in them.
