FIELD: transport.
SUBSTANCE: invention relates to the device and method of signalling about abnormal tire air pressure under unusual conditions, for example, with the shift of load on vehicle or with anti-skid chain applied onto one wheel. The proposed device incorporates an appliance designed to compare the wheel running speed of appropriate tires and to pinpoint which particular wheel runs at lower speed compared to the others.
EFFECT: higher accuracy of signalling about abnormal tire air pressure.
