ABS problems
It sounds like you have a wheel speed that is going out. But check your tire pressures. I am also assuming you have the same tire size all around.
circumference seems to be where the pain comes in) the
ABS doesn't care. I think the sensors are the best bet, an
intermittent connection or a loose mounting position.

Assumming you have no wiring issues, I would say you probably have a wheel speed sensor on the way out. Keep in mind the front sensors are incorparated into the hubs and if one is going bad, it will also effect the wheel speed sensor.
JimmyBlue,
The actual difference in tire circumference between tires is 6%, but if you take into acount turning 3% is about as much as you can safely go without setting a fault.

The tire sizes you use in your example will definately set a fault.
