TIRE

In a tire, a main groove is formed in a step shape including circumferential extending portions extending in a circumferential direction at positions where positions in a width direction differ. Inclination directions of a second lug groove and a shoulder lug groove in the circumferential direction with respect to the width direction are opposite to one another. In the second lug grooves, two types of the second lug grooves having differentinclination angles with respect to the width direction are alternately disposed. The second lug groove opens to the circumferential extending portion located close to the second lug groove among the circumferential extending portions included in respective center and shoulder main grooves formed in step shapes. A shoulder lug groove opens to the circumferential extending portion located close to the shoulder lug groove among the circumferential extending portions included in the shoulder main groove formed in the step shape.
