摘要： A pneumatic tire in which a sipe, which is substantially parallel to a contour line of a trailing edge of a ground-contact configuration, is formed in a trailing edge region of each block at shoulder sides of the pneumatic tire. From a time of step-in to a time of kick-out of a block, the effect of shearing strain which is transmitted to a trailing edge from a preceding trailing edge portion is mitigated, and movement of the trailing edge of the block with respect to a road surface is suppressed. Accordingly, wear at the trailing edge of the block, i.e., heel-and-toe wear, is suppressed, and noise caused by heel-and-toe wear is reduced.

摘要： A high efficiency all terrain bicycle or motorcycle tire having a tread design in which spaced tread blocks are arranged in circumferential rows and overlapped to allow a smooth shift in load from one tread block to another in different circumferential rows with a minimum of casing hysteresis and at the same time provide a low rotating mass, low rolling resistance, high cornering adhesion with high consistency across differing types of ground conditions, high motive and stopping traction. The tread blocks in the different rows have shapes, spacings and orientations which createa plurality of tortous paths for flow of material without excessive constricting of flow in any one spot.

摘要： An asymmetric directional tread for a tire is disclosed. The tread has a plurality of ground engaging tread elements separated by grooves. The grooves include one wide circumferentially continuous groove having a width W, a plurality of circumferentially continuous grooves of an intermediate width between greater than 1/3 and 3/4W, at least one narrow circumferentially continuous groove having a width 1/10 to less than 1/3W located between a lateral edge and a circumferentially continuous groove of a greater width, and first and second sets of laterally extending grooves. The first set extends from the outboard lateral edges to an end location within 5% of the tread width from the equatorial plane. The second set extends from the inboard lateral edge to an end location within 5% of the tread width from the equatorial plane.

摘要： The tread design of a radial pneumatic tire for ground vehicles is characterized by lateral or transverse grooves on the shoulder ribs having an incline from the normal to the contact surface in one direction and the lateral or transverse grooves in the center of the tread width being inclined in the reverse direction. Improved wear rates with uniform wear is obtained on a drive axle with proper tire rotation. A reversed direction of rotation on the non-drive axle results in more even wear with potentially less vibration and noise.Lateral grooves are inclined form approximately 20 to 30 degrees and leading edges of some tread blocks have acute angles while other tread blocks have trailing edges with acute angles. The resultant distribution of longitudinal tangential stress on tread blocks is improved.

摘要： The present invention relates to a radial tire and a radial tire-rim assembly. The radial tire (1) has a pair of beads (2), each bead having a bead core (3) and a bead apex (5), a carcass (4), with both edges thereof folded back around said bead core and fastened to said bead core, a tread (6), a belt layer (7), and an aspect ratio smaller than 60%. The tread is wider (in the axial direction) than the maximum width of said carcass and the edges of said tread are positioned within a range of 50-100% of the height of the cross-section of the carcass. This structure provides the tire side with rigidity and permits the tread to deform so that is supports the weight of the car and runs safely even when the tire pressure is decreased. The radial tire-rim assembly is characterized in that the bead of the radial tire has a toe (9) extending inward (in the radial direction of the tire) and is further provided with a hump groove (10) corresponding paramently,, the rim (20 ) has an annular groove (22) and hump (23) which fit into the toe and groove, respectively. These arrangements prevent the bead from separating from the rim when the tire pressure is decreased or at a time of sharp cornering.

摘要： A vehicular tire having a tread configuration that provides a cornering stiffness in one axial direction that is greater than the cornering stiffness in the opposite axial direction. The difference derives from an asymmetrical configuration of the tread. The tread is provided with a plurality of circumferential ribs that define circumferential grooves therebetween, the ribs having walls on one side that define a relatively flat continuous surface facing in one axial direction to provide a relatively rigid rib edge and on the side that faces in the opposite axial direction, an irregular configuration to provide a rib edge of less rigidity.
