Abstract

A two-wheeled vehicle tyre (1) includes a tread portion (2) including a tread rubber (9). The tread rubber (9) includes a cap rubber (9c) forming a tread surface (2a) and a base rubber (9b) disposed radially inwardly of the cap rubber (9c). 300% modulus (M300c) of the cap rubber (9c) is greater than 300% modulus (M300b) of the base rubber (9b). Loss tangent (tan δc) of the cap rubber (9c) is smaller than loss tangent (tan δb) of the base rubber (9b). The tread surface (2a) includes a crown region (Cr) centered on a tyre equator (C) and a pair of shoulder regions (Sh) located axially outwardly of the crown region (Cr), and a thickness (tc) of the cap rubber (9c) in the crown region is greater than a thickness (tc) of the cap rubber (9c) in each of the shoulder regions (Sh).
