Process and device for detecting a condition of a tyre tread without pressure of a vehicle hired, design element of security, tyre and wheel ".The process of detection of a condition without pressure of a pneumatic tyre of a vehicle, said tyre being mounted in a wheel, such that: captures is a magnitude f ( 244 ,T) that varies with the angular displacement of the wheel in time; producing signs of measure that vary with the angular velocity of the wheel d 244 (T) / dt; it is a characteristic quantity of the spread ofSigns of measure; shoot an alarm when the characteristic quantity satisfies a given ratio.
