Abstract: The present invention concerns a method for measuring the wear of a tire (2) having tread pattern elements interconnected by grooves, which is mounted on a wheel fitted on an automobile having a chassis and a suspension system (1), the method including, when the vehicle (13) rolling or at rest, the following steps: at a given moment a reference value is measured, which is representative of the distance between, on the one hand, a first point fixed on the suspension system (1) or a second point fixed on the chassis facing the tire (2), and on the other hand the top of at least one of the tread pattern elements opposite, ii) in a first case, at the given moment a reference value is measured which represents a distance measured between the first or second point and the bottom of one of the grooves opposite, or, alternatively, in a second case, another reference value is measured subsequently, which represents a distance measured between the first point and one of the tops, and iii the value measured in i) is com
