Back again, checked tire diameters and they are the same. Had trouble and could not remove ABS sensor, got clip off ok but was afraid of breaking the sensor, seemed like it was in there pretty tight. One thing I did notice that I did not check when doing front breaks was that the rears are in dire need of adjustment, there is no drag at all so I am back to find out how to adjust them and what tips I can find on removing sensors without destroying. I'll keep you posted, any comments/advice in the mean time will be greatly appreciated.
