A tire 1 comprises a tread portion 2 comprising shoulder blocks 3 and crown blocks 4. The shoulder blocks 3 each has a ground contacting surface (3t) comprising an axially outer portion 6 extending axially inwardly from one of tread edges (Te) and a steeply oblique portion 7 extending axially inwardly from the axially outer portion 6 with a larger inclination angle with respect to the tire axial direction than the axially outer portion 6. The crown blocks 4 each has a ground contacting surface (4t) comprising a first oblique portion 10 inclined oppositely to the steeply oblique portion 7 and a second oblique portion 11 extending from and obliquely and oppositely to the first oblique portion 10. In a development view of the tread portion 2, longitudinal directions of the steeply oblique portion 7 and the first oblique portion 10 intersect at an angle from 70 to 110 degrees.
