Speaking from experience, it will cause the wheel speed readings to differ slightly. At highway speeds, the ABS computer will see it as slipping wheels, and cut the engine power until the condition is corrected. Trust me, it is no fun coasting down to forty mph on the highway in a seventy mph zone. How do I know this? My wife's 2006 Vue had that happen when the tire people installed the wrong tires on the back of it (I did not check their work either). We got out on the highway, in the leftmost lane, going seventy five mph, and all of the sudden, with no warning, the throttle quit working until it slowed down to somewhere around forty mph. That is an experience that I do not need again.
So in short, stay with tires that match in size and load rating all the way around.
