I see where you are coming from... What you seem to be describing is a "passive TPMS" system where the computer uses wheel speed to "calculate" if there is a low tire. But I'm 100% sure the Raptor uses a "direct TPMS" system that is not tied into the wheel speed sensors. In other words, the valve-stem mounted sensor in the Raptor tire measures the tire pressure directly and transmits the pressure information via radio waves to the receiver located in the Smart Junction Box.
