You may have burned something in the esc. You need to remeber when you change tire/wheel size your basically changing your final gear ratio. So by all rights you should have re geared for those bigger wheels and tires.

I assume this is a brushless ESC/motor? There is no "reverse" set of FETs, direction is controlled by the order in which the coils are energized. That's weird.
And like Jason said, depending on the size tire, you should gear down at least 1-2 teeth.
