摘要： In a pneumatic tire, one end of a first lug groove opens to an edge of an inner second land on the ground contact edge side, and at the other end terminates within the inner second land. One end of the second lug groove opens to the edge of the inner second land on a equatorial plane edge side, and the other end terminates within the inner second land. The first and second lug grooves are alternately arranged in the circumferential direction. In a region on the outer side in the width direction, a circumferential main groove on the equatorial plane side defining the outer second land has a bent shape with an amplitude in a lateral direction, and includes an acute angle bend bending at an edge on the equatorial plane side. The outside second land includes a lug groove opening to a position facing the bend.

摘要： In a stud pin, a flange contour shape of a lower flange is an anisotropic shape in which, among imaginary rectangles circumscribing the contour shape, the smallest rectangle includes short sides and long sides having different lengths. The flange contour shape includes first recess portions on each of portions of the flange contour shape extending along the short sides, the first recess portions being curved toward a centroid of the flange contour shape, and the flange contour shape includes a second recess portion on portions of the flange contour shape extending along the long sides, the second recess portions being curved toward the centroid of the flange contour shape. A body contour shape of a body portion is a polygonal shape including vertex angles in a same number as the first and second recess portions, and the vertex angles are disposed facing the first and second recess portions.

摘要： A pneumatic tire includes two circumferential main grooves disposed in the region on one side of a tire equatorial plane as a boundary and a land portion defined by the two circumferential main grooves. The land portion includes a circumferential narrow groove extending in the tire circumferential direction and sets of a first and a second lug groove extending in the tire lateral direction through the circumferential narrow groove. The first lug groove includes an end portion that opens to the edge portion on one side of the land portion and another end portion that terminates within the land portion. The second lug groove includes an end portion that opens to the edge portion on the other side of the land portion and an end portion that terminates within the land portion. The first lug groove and the second lug groove are alternately disposed in the tire circumferential direction.

摘要： A pneumatic tire includes a carcass layer, a belt layer, a tread rubber having a cap tread and an undertread, a pair of side wall rubbers, a pair of rim cushion rubbers, and an earthing tread that is exposed to a road contact surface of the tread rubber and that penetrates the cap tread and the undertread to contact the belt layer in an electrically conductive manner. The earthing tread includes a widened portion having a cross-sectional area that widens toward a contact surface with the belt layer at the contact portion with the belt layer. The widened portion of the earthing tread has a profile shape that bulges outward in a tire width direction.

摘要： The present technology provides a pneumatic tire having a strip-shaped sound-absorbing member bonded on the inner surface of the tire includes a plurality of belt layers, two or more belt cover layers, one or more belt edge cover layers, and a thread rubber layer. The thickness of the tread rubber layer is substantially uniform in the region X where the sound-absorbing member is located so that the difference between the thickness t1 at an end of the sound-absorbing member and the thickness t0 at the position of the tire equator is equal to or less than 0.5 mm. The thickness of the tread rubber layer is smaller in the region Y where the belt edge cover layer is located than in the region X so that the difference between the minimum value t2 of the thickness in the region Y and the thickness t0 ranges from 1.0 to 4.0 mm.
