Abstract: The present invention is directed to provide a pneumatic tire capable of effectively preventing large collision noise due to simultaneous collision of plural blocks of respective rows with a road surface. Six rows 9, 10, 13 of blocks on a tread surface 1 are defined by five circumferential grooves 2, 3, 4 continuously extending in a tread circumferential direction in a zigzag manner, a plurality of lateral grooves 5, 6, 11 extending in a tread widthwise direction between the circumferential grooves adjacent to each other and between the outermost circumferential grooves 4 and respective tread side edges e. Five circumferential grooves 2, 3, 4 comprise narrow circumferential grooves 2, 4 and a pair of wide circumferential grooves 3 disposed on each side of the tire equator line and having a width greater than that of the narrow circumferential grooves 2, 4. The lateral grooves 5, 6 are inclined with respect to the tread widthwise direction. Each of the blocks 7, 8, 12 of the block rows 9, 10, 13 has a polygon planar contour shape with six or more sides such that a minimum length of the block in the tread widthwise direction is situated in an end portion of the block in the tread circumferential direction and a middle portion of the block in the tread circumferential direction has a length greater than the length of the end portion in the tread circumferential direction. Leading edges 7a, 8a, 12a of the blocks 7, 8, 12 of each rows 9, 10, 13 when the tire is rolling under load are spaced from each other in the tread circumferential direction.

Abstract: A valve for a safety tire is provided which allows air to be separately supplied into an inner air chamber and an outer air chamber of a tire having a double structure and which allows air to be separately released from these air chambers. A first hollow stem 22 of a valve 20 includes a hole 34 communicating with an inner air chamber 14, and a hole 35 communicating with an outer air chamber. A valve core 41 is disposed in each of the holes 34 and 35. A detachment-restraining adapter 105 is screwed into the hole 35 at a side opposite to the side at which a tire is disposed. As a result, air supply and air release for the inner air chamber 14, and air supply and air release for the outer air chamber 15 can be separately carried out using a simple structure.
