Abstract
A method for obtaining the distance travelled by a tire comprises fixing a sensor, to the right of the crown with a radial position Rc, capable of generating a signal proportional to the acceleration experienced; rolling the tire at a rotation speed W, subject to a load Z; acquiring, after a time T, a first signal Sigcomprising the acceleration amplitude in the direction normal to the crown, wherein the values below a threshold N represent less than 40 percent of the length of the first signal; identifying a reference value V, being the square root of the average value of the first signal Sig; and determining the distance travelled D during the time T from the following formula: D=A*T*V, where A is proportional to the square root of the rolling radius of the tire.
