The shoulder blind grooves extend axially inwardly from one of the tread edges and each having an axially inner blind end. The shoulder main groove extends circumferentially of the tire on the axially inside of the axially inner blind ends of the shoulder blind grooves. Each shoulder blind groove is provided with an axially inner shallow part, an axially outer deep part, and a sloped part therebetween having a depth gradually increasing from the shallow part towards the deep part, and having an axially outer end positioned at a distance from the tire equator which is 42.5 % to 45 % of the tread width. |
