Abstract: A solid tire (4; 8) is described comprising two or more circular layers overlapped in a radial direction. At least the outermost layer is made of elastic material and consists of an external portion or tread (16). The solid tire (4; 8) furthermore comprises at least one layer for indicating excessive wear (10), arranged in a predefined position inside the outermost portion or tread (16). The layer for indicating excessive wear (10) is made in a colour different from the one of the external portion or tread (16). The layer for indicating excessive wear (10) is made with a specific compound of materials. This specific compound of materials makes the layer for indicating excessive wear (10) easy to see. This specific compound of materials also makes the solid tire (4; 8) less hysteretic, and therefore less subject to the development of heat, when compared to similar solid tires.
