ABS will only tolerate so much difference between front and rear wheel speed before activating (with the brakes) or throwing a code.

Speedo' and the odometer will both be off... Do a minimum 10 mile run using a good GPS unit or measured miles on a highway to get the differential between milage reading of new tires and old... My snow tires are about 5% larger in circumference than the regular tires so I note that when I compute my fuel milage...
