Calibrate Speedometer

Trying to calibrate my speedo for the new tires and im not sure its doing anything. I adjusted the revs per mile to what the new tires are and my GPS is still showing 4-5 mph higher than speedometer. Original tires revs per mile was 649 i think and my new tires are 579...
Any advice would be much appreciated.
