In a tire cross-section including a tire axis under a 5% inner pressure condition where the tire is mounted on a standard wheel rim with 5% of a standard pressure but is loaded with no tire load, the tread portion (2) has a profile which includes a first profile (21) including the tire equator, a pair of second profiles (22) extending axially inwardly from the tread edges (TE) and a pair of third profiles (23) connecting the first profile (21) and the respective second profiles (22).
