摘要： Provided is a studdable tire that can exhibit excellent on-snow performance as well as on-ice performance.
A studdable tire 101 has a tread portion 102 to which a stud 103 is mounted. The tread portion 102 has a designated rotation direction R. The tread portion 102 includes a plurality of blocks 105 and a lateral groove 106 which is adjacent to each block 105 on a rear side in the rotation direction. The lateral groove 106 includes a gently-tilted portion 107 that extends at an angle of not greater than 30 degrees relative to a tire axial direction. The stud 103 is mounted to at least one of the plurality of blocks 105. The stud 103 includes a body embedded in the block 105 and a pin portion 120 that projects from the body in a tire radial direction. The body has a top flange 111 formed in an outer side portion in the tire radial direction. The top flange 111 includes a tapered portion 111A in a planar view. The top flange 111 is disposed such that the tapered portion 111A is oriented toward the rear side of the block 105 in the rotation direction R.-

摘要： A tire has a tread having a first tread edge, a second tread edge on the opposite side, and multiple inclined main grooves formed such that each inclined main groove is obliquely extending from one of the first and second tread edges toward a tire equator and is terminated without reaching the other one of the first and second tread edges. The inclined main grooves are formed such that each of the inclined main grooves includes a tire axial direction outer side portion obliquely extending in an inclined direction, a tire axial direction inner side portion inclining in the inclined direction, and a middle portion formed between the tire axial direction outer side portion and the tire axial direction inner side portion and inclining in the opposite inclined direction with respect to the inclined direction of the tire axial direction outer side portion and tire axial direction inner side portion.

摘要： A first and a second tread pattern portions (P1) and (P2) on each side of a tire equator (Co) are line symmetry except being circumferentially misaligned, and are each provided with oblique lateral grooves (3), inner and outer joint grooves (4) and (5) connecting between the circumferentially adjacent oblique lateral grooves (3), inner terminating grooves (7) disposed between the inner and outer joint grooves (4) and (5), outer terminating grooves (8) disposed between the outer joint grooves and a ground contact edge (TE), and center joint grooves (6) alternately connecting the oblique lateral grooves of the first and second tread pattern portions. The inner and outer joint grooves (4) and (5) and the inner and outer terminating grooves (7) and (8) are inclined to different directions from the oblique lateral grooves (3). The outer terminating grooves (8) extend on extended lines of the outer joint grooves (5).

摘要： A tire capable of exhibiting excellent on-ice performance is provided. The tire includes a tread portion 2. The tread portion 2 includes a recess 7 that is recessed from a ground-contact surface 2s thereof. The recess 7 includes a bottom surface 8 and an inner circumferential surface 9 that is connected to the bottom surface 8 and the ground-contact surface 2s. The recess 7 is provided with a stud pin-fixing hole 5 that is open in the bottom surface 8, and a plurality of projections 10 that project from the bottom surface 8. The projections 10 include a first projection 11 that is connected to the ground-contact surface 2s and that projects outward in a tire radial direction of the ground-contact surface 2s.

摘要： Provided is a studdable tire that can exhibit excellent on-snow performance as well as on-ice performance.
A studdable tire 101 has a tread portion 102 to which a stud 103 is mounted. The tread portion 102 has a designated rotation direction R. The tread portion 102 includes a plurality of blocks 105. The plurality of blocks 105 each include a corner portion 106 that projects forward in the rotation direction R. The stud 103 is mounted to at least one of the plurality of blocks 105. The stud 103 includes a body embedded in the block 105 and a pin portion 120 that projects from the body in a tire radial direction. The body has a top flange 111 formed therein, and the top flange 111 includes a tapered portion 111A in a planar view. The stud 103 is mounted to the block 105 such that the tapered portion 111A and the corner portion 106 are oriented in the same direction.
