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： Provided is a tire having improved braking performance while maintaining noise performance. The tire includes a tread portion 2 having a designated rotation direction R. The tread portion 2 includes a first tread end T1, first inclined grooves 5, and first land portions 7. Each of the first inclined grooves 5 includes a first groove wall 11 on a leading edge side in the rotation direction R and a second groove wall 12 on a trailing edge side in the rotation direction R. A first chamfered portion 13 is formed on the first groove wall 11, and a second chamfered portion 14 is formed on the second groove wall 12. In a cross-section orthogonal to a groove center line of the first inclined groove 5, a chamfered area S1 of the first chamfered portion 13 is larger than a chamfered area S2 of the second chamfered portion 14.

摘要： A tire includes a tread portion 2 having a designated rotation direction R. The tread portion 2 includes a first tread end T1, a first middle position 10, and first inclined grooves 5. An inner end 5i of each first inclined groove 5 in a tire axial direction is located on a tire equator C side with respect to the first middle position 10. In each first inclined groove 5, an angle relative to a tire circumferential direction at the inner end 5i is smaller than that at the first middle position 10. Each first inclined groove 5 includes a first groove wall 11 on a leading edge side and a second groove wall 12. In an inner region 5A of each first inclined groove 5, the second groove wall 12 includes a chamfered portion 15. In a cross-section orthogonal to a groove center line of the first inclined groove 5, a chamfered area of the chamfered portion 15 increases toward the inner end 5i side.

摘要： A tire has a tread portion including a first shoulder land region. The first shoulder land region is provided with first shoulder sipes. Each of the first shoulder sipes is provided with a chamfered portion over an entire lengthwise range from a first longitudinal edge to a first tread edge. Each of the chamfered portions includes a first chamfered portion defined between a shoulder center position and the first longitudinal edge and a second chamfered portion defined between the shoulder center position and the first tread edge. The second chamfered portion has a chamfer volume larger than a chamfer volume of the first chamfered portion.

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. -
