Abstract: A groove bottom of a circumferential groove formed in a tread surface is provided with a protruding stripe extending along an extending direction of the circumferential groove. The protruding stripe is provided with a top head portion protruding toward a tire outer circumferential side, and a base portion which is narrower than the top head portion and connects the top head portion and the groove bottom. If a small stone is pinched, the top head portion is inclined around the base portion, and the protruding stripe is deflected as a whole, thereby generating a reaction force on the basis of a deformation restoring force.

Abstract: The present invention provides a heavy load pneumatic tire capable of effectively preventing a river wear from generating while preventing a crack or a stone-biting from generating in a sipeing end. In a heavy load pneumatic tire in which a tread portion has a rib pattern formed with ribs divided by main grooves which are continuous in a circumferential direction of the tire, at least one of the main grooves that is located on the outermost side in a widthwise direction of the tire is provided at its groove bottom with a projecting stripe which is continuous in the circumferential direction of the tire, and the ribs adjacent to an inner side of the main groove are provided with closed sipeings arranged at substantially constant distances from each other.

Abstract: A pneumatic tire includes a plurality of protrusions on a bottom of each of the grooves. The height of the protrusion is variable in a profile of the protrusion in a circumference direction of the pneumatic. The protrusion has at least one peak portion that protrudes away from a center of the pneumatic tire. The pneumatic tire further includes a connection member between the protrusion and an adjacent one of the lands, the connection member having a first end toward the land and a second end toward the peak portion, a height of the first end from the bottom of the groove being larger than that of the second end.

Abstract: An opaque article having a surface and substantially asymmetric striae extending along the surface. A portion of the striae reside in a first area and have an orientation. Another portion of the striae reside in a second area and have an orientation substantially opposite the striae in the first area. The first area striae and the second area striae create an optical contrast therebetween at a wide range of viewing angles and illumination angles. The opaque article can be a tire. The striae can reside at numerous locations on the tire, including, for example, the sidewall, tread ribs or blocks, and stone ejectors.

Abstract: A radial tire for heavy duty vehicles has a tread surface provided with at least a main groove (4) extending in the tire circumferential direction, a slot (9) with a slot width (HS) of 3 to 6 mm, and siping (11). A groove bottom (3) of the main groove (4) is in a zigzag form, and a groove upper edge line (8) of the main groove (4) on the tread surface has outer and inner groove upper edge line (M1, V1) repeated alternately and each extending in the tire circumferential direction. The distance (hu) in the tire axial direction between the outer and inner groove upper edge lines (M1, V1) is smaller than the deflection width (hl) of the zigzag groove bottom. The groove wall of the main groove (4) has hill protrusions (6) each having an inclined groove wall part (5) extending from the external angle portion (M) of the zigzag groove bottom to the outer groove upper edge line (M1). The slot (9) is formed in the inclined groove wall part (5) with the depth (DS) in the tire axial direction from the inclined groove wall part (5) increasing gradually inward in the tire radial direction. The siping (11) is formed in the inside wall (10) of the slot (9) with the depth (DC) in the tire axial direction from the inside wall (10) being constant or increasing gradually inward in the tire radial direction.
