The present invention relates to a tyre (1) for a heavy-duty vehicle for urban use and aims to improve the visibility of a sidewall wear indicator (6), and therefore the reliability of the measurement of the residual thickness of the outer sidewall layer (2). According to the invention, with at least one sidewall (2) comprising, on an outer sidewall face (21) in contact with the atmospheric air, at least one wear indicator (6) that is recessed with respect to the outer sidewall face (21), every wear indicator (6) has an open section (61) on the outer sidewall face (21) containing an inscribed circle (7), the diameter (D) of which decreases continuously as the sidewall (2) becomes worn, and every wear indicator (6) has a non-smooth inner wall (62) comprising a distribution of elements (63) that are raised or recessed with respect to the inner wall (62), and/or a texture (64) that is raised with respect to the inner wall (62), such that the inner wall (62) contrasts visibly with the outer sidewall face (21).
