Abstract
A method of detecting a deflated tire on a vehicle by comparing the rolling radii of the tires by comparing angular velocity speed signal values from wheel speed sensors provided on each of the wheels wherein whenever the tires are re-inflated or changed, a semi-automatic standardization procedure is initiated by the driver to enable the deflation warning system to automatically recalibrate the relative wheel speed signals.
