Sorry Mac but I think you'll find this is incorrect. The computer takes into account the difference in rotation speeds between the front and rear wheels and uses this information to make decisions about ABS operation. So if you fit different sized wheels you have to re-program the ECU to take account of this, otherwise you bugger up the ABS operation.
