ABS actuation occurs from a detected "slip" during braking. It does this by monitoring the wheel speeds to determine is one wheel(or two rear wheels for the 3rd channel in the 240) sees a sudden drop in wheelspeed during breaking. So having a different diameter wheel of the same size all around would not upset this system at all. Staggered set-ups have the potential for doing so, but it depends on the threshold set by the manufacturer and the actual differences in tire diameters. There will usually be plenty of slop built in to account for uneven tire wear and to prevent premature activation. My G35 will see a moment of lock-up before the system kicks in. having a larger difference in diameter may cause the ABS to kick in faster though. There are a lot of variables that the manufacturer would only be able to answer though. Minor differences should be fine in just about any system though.
