PURPOSE: To provide a high wet skid resistant performance and well restrain partial abrasion by applying the constitution that a land section forms a row of many blocks divided with open sipes having both ends open to right and left main grooves, respective blocks are extended along the open sipes, and also the land section has closed sipes having both ends terminated in the blocks. CONSTITUTION: The tread 1 of a pneumatic tire for a heavy load has a plurality of meandering main grooves 2 extended in a peripheral direction, and a land section 3 divided with the main grooves 2. Also, the section 3 has sipes 4 and 6 extended along a direction intersecting the main grooves 2. The main grooves 2 are continuous with meandering width (w) equal to or less than the width (v) thereof. Also, a row of many blocks 5 is formed in such a state as divided with the open sipe 4 having both ends open to the right and left main grooves 2 of the section 3. In addition, the blocks 5 are extended along each open sipe 4, and has a closed sipe 6 having both ends terminated therein. |
