ABSTRACT:
A method of detecting a deflated tire on a vehicle by comparing the rolling radii of the tires by means of comparing angular velocity speed signal values C1, C2, C3 and C4 from wheel speed sensors on wheels 1-4 at the left-hand front, the right-hand front, the left-hand rear and the right-hand rear wheel position respectively, comprising the step of calculating an error value DEL' in normal driving by processing the four angular velocity speed signal values C1-C4 in a central processing unit (10) which subtracts the sum of the signal values from one pair of diagonally opposite wheels from the sum of the signal values from the other pair of diagonally opposite wheels and expressing the results as a percentage of the mean of the sums
