Abstract: A wheel tread part 2 of a tread is constituted of a longitudinal main groove 3 formed in a circumferential direction via a center of a width direction, a plurality of longitudinal subgrooves 4 formed on both side parts of the longitudinal main groove 3 in the circumferential direction, and a plurality of traverse grooves 5 formed in a width direction to intersect the longitudinal main and subgrooves 3, 4, and divided into a plurality of blocks 6. Each of the plurality of blocks 6 is provided with a one-end-open sipe 9, and formed so that rigidity in the width direction can be higher in an end a of a center side region compared with an end b of a shoulder side region. Since the rigidity of the end a of the center side region is higher, a reaction force is generated in accordance with a steering angle from the start of changing the same.

Abstract: A pneumatic off-the-road (OTR) tire has a plurality of central and shoulder lugs. The central lugs are arranged in a circumferentially continuous row and extend across the equatorial plane (EP). Each central lug is similar in shape and orientation relative to each circumferentially adjacent central lug. The tire is conformed having a tread package that effects a low net-to-gross ratio of less than 40% as measured around the circumference of the tire. The low net to gross tread pattern is incorporated into a relatively low aspect ratio OTR tire for construction and industrial applications.

Abstract: A method for changing the residual aligning torque (RAT) of a pneumatic tire by forming angled sipes in certain of the tread blocks in at least a pair of circumferentially extending ribs, each rib being located on an opposite side of the mid-circumferential plane of the tire. The sipes in the tread blocks in one of the ribs are formed at an inclined angle opposite to the inclined angle of the sipes in the tread blocks in the opposite rib. The RAT can also be changed by varying the depth and width of the opposed angled sipes.

Abstract: A pneumatic tire for use on iced and snowed road surfaces has a tread surface. The tread surface has a plurality of main grooves extending in a circumferential direction of the tire and a plurality of lateral grooves extending in a width direction of the tire. Blocks are defined by the main grooves and the lateral grooves. The blocks have a ground contact face which has a plurality of pairs of sipes comprising a left sipe and a right sipe extending in the tire width direction. The plurality of pairs of sipes are placed in a predetermined interval in the tire circumferential direction. Each of the left and right sipes of each pair extends from a width-directional center portion of the ground contact face of the block toward each way of the tire width direction so as to open its outer end to each side face of the block.

Abstract: In a pneumatic tire, a block unit includes a center block and side blocks separated by a communication groove. Aspect ratios of the center block and the side blocks are approximately the same. The center block and the side blocks are arranged such that a longitudinal direction of a rectangle relating to the aspect ratio of the center block and longitudinal directions of rectangles relating to the aspect ratios of the side blocks are approximately orthogonal to each other. Size ratios of a short side of the rectangle relating to the aspect ratio of the center block and the long sides of the rectangles relating to the aspect ratios of the side blocks are in a range equal to or more than 0.90 to equal to or less than 1.10.

Abstract: A pneumatic tire including sipes that have at least one ends positioned within blocks. The sipes are arranged such that each of the sipes meanders from the one end to the other end thereof to form a meandrous shape, and as the depth of the sipes increases, the meander width of the sipes gradually increases from their openings to at least the 80%-worn position of the blocks. The sipes each have a sipe length L, which is defined as a center line length between an intersection of a center line passing the center of the meander width of the meandrous shape with a first straight line and an intersection of the center line with a second straight line, the first straight line being orthogonally drawn to the center line from the one end of the sipe and the second straight line being orthogonally drawn to the center line from the other end of the sipe at the same depth position of the sipe, the sipe length L gradually decreasing as the sipe depth increases. The ratio L80/M0 of the sipe length L80 at the 80% worn position to the opening length M0 of the sipes is in the range of 0.8 to 0.95, and the ratio M80/M0 of the actual length M0 of the sipes at the 80% worn position to the opening length M0 is in the range of 1.0 to 1.15.
