I mean really even if it has a center diff you want the same size tires unless its 2wd. A differential lets each side turn at different rates, like left and right wheels, so when your turning the outside wheel can turn faster than the inside. And when your racing you want the front wheels to pull you out of a corner, not the rear wheels pushing cause your more likely to spin out. But a 2 speed is basically a locked center. So the front and rear tires have to spin at the exact same rates, vs the diff will let the front whells spin faster than the rear, thus pulling.

If you have a 2 speed or a center slipper and you say have the rear wheels bigger than the front. The front wheels will have to skip and turn faster than the rears. It will put stress on the drive train and isnt good for it.

And if you have a center diff you will be constantly spinning it which will put a lot of wear on it. Im sure it would work, but wouldnt be good in the long run i bet.
