I believe ABS works on the acceleration of the wheels, not the
speed. (Accleration being the rate of change of the speed.) The
tire diameter should not effect this per se. The tire diameter
would effect the rotating moment of inertia of the tire/wheel
assembly, but this should be no more than switching tire types like
snow to regular tires.
I think the ABS should work with any tire/wheel. I also think
that the tire stores would be aware of this and the aftermarket
wheel market would shrink as more cars and trucks get ABS.
Drive Safe,
