Lower than it actually is. Your speedometer is measuring the number of rotations of the axle. Since the diameter of your tires is larger, the circumference is larger, and thus, you travel a greater linear distance on each rotation.
Greater distance/same number of rotations=greater velocity

B- lower being that there is more surface area to the larger tire.

the same as the original tires...but you will be moving faster because you have a larger tire.
