Vehicle tires as well us sytem and method for measuring the deformation of vehicle tires

The radial inner and outer tracks of pair of tread side walls (2), has several magnetic sectors angularly arranged at different radial spacings and the sector transitions which separate the adjacent sectors, radially extended at varying angles with respect to the radius of tire (1). The sectors of outer track are held at greater spacing than the sectors of inner track. Independent claims are included for the following: (1) deformation measurement system for vehicle tire; and (2) deformation measurement method of vehicle tire.
