That would be very naughty of the manufacturer on a 2012… the wheel speed sensor would be connected to a computer and speed PID reported on the canbus, the computer should be calibrated to the trim level of the car (and the wheels that it came with) to report the correct speed.

Having said that manufacturers often overestimate speed by ~5% to prevent being blamed for speeding offences.
