摘要：A device for evaluating the deformation of vehicle tires running along theground comprises: means (10, . . . , 32, 34, 40, . . . ) for measuring the length (1.sub.1) of afirst chord of said tires (1), said first chord extending along a first direction at a firstdistance from said ground; means (40) for calculating a theoretical length for a secondchord of said tire located at a second distance from the ground as a function of thelength of said first chord and of said first distance from the ground; means (10, . . . , 37, 40,. . . ) for measuring the length (1.sub.1) of said second chord of said tire (1) situated at saidsecond distance from the ground; and means (40) for comparing the theoretical lengthof said second chord with the measured length of said second chord, and for generatingan output signal representative of said comparison.
