1. A tire for a two-wheeled motorized vehicle, of a motorcycle type, comprising a tread that is connected by two sidewalls to two beads, each bead comprising a circumferential reinforcing bead wire, said beads being intended to come into contact with a rim on which the tire is intended to be mounted,
the tire comprising an indicator system that comprises a plurality of cavities formed on the surface of the tread, each cavity having a maximum depth of less than 1 mm and an average width of less than 3 mm,
the cavities being arranged in a plurality of circumferential sets of cavities, wherein each circumferential set of cavities represents a different camber angle of the tire,
each circumferential set of cavities comprising a plurality of cavities that are distributed circumferentially in a circular arc, wherein two adjacent cavities are spaced apart along the circular arc by a circumferential pitch of between 1 mm and 10 mm,
the circumferential sets of cavities being arranged in a specific radial pattern, the radial pattern being defined by a radial pitch that corresponds to the spacing in the radial direction between the circular arcs of two adjacent circumferential sets of cavities, the radial pitch being between 1 mm and 10 mm,
wherein the cavities of the circumferential sets of cavities have depths and/or average widths that increase with a corresponding positioning of a tire camber angle; and
wherein two adjacent cavities are spaced apart along the circular arc by a circumferential pitch of between 1 mm and 8 mm.
