Abstract: A tread portion includes a crown land portion including first and second longitudinal edges extending in the tire circumferential direction. The crown land portion is provided with first, second and third crown sipes. The first, second and third crown sipes open at the ground contact surface via respective chamfer portions. The first and third crown sipes extend from the first longitudinal edge and have closed ends in the ground contact surface. The second crown sipes extend from the second longitudinal edge and have closed ends in the ground contact surface. Each first crown sipe has a constant opening width in a longitudinal direction of the sipe. Each second crown sipe has a constant opening width in a longitudinal direction of the sipe. Each third crown sipe has an opening width which decreases continuously from the first longitudinal edge toward the closed end thereof.

Abstract: Provided is an evaluation method capable of evaluating stress on a bond which is difficult to detect by Raman spectroscopy. The present disclosure relates to an evaluation method including using infrared absorption spectra measured on a rubber specimen under application of no tensile force and under application of a tensile force to calculate an amount of peak shift caused by application of the tensile force, and evaluating stress in the rubber specimen from the amount of peak shift.

Abstract: Provided is a tire that allows reduction of uneven wear such as heel-and-toe wear around a plurality of closed sipes.
The tire includes a tread portion 2. A plurality of closed sipes 8 are aligned in a tire axial direction in a land portion 4 of the tread portion 2. Each of the closed sipes 8 includes a sipe bottom 8d, a first end 8a and a second end 8b, a first sipe piece 11, a second sipe piece 12, a third sipe piece 13, and at least one tie bar 20. The closed sipes 8 aligned in the tire axial direction overlap each other in the tire axial direction and a tire circumferential direction. The tie bar 20 includes a first tie bar 21. A center, in a sipe length direction, of the first tie bar 21 is disposed closer to a first intersecting portion 18 than a center, in a length direction, of the first sipe piece 11 is. A distance from the first tie bar 21 to the first intersecting portion 18 is not greater than 25% of a length of the first sipe piece 11.-

Abstract: A tire comprises a tread portion having a tread surface and buttress surfaces. The buttress surfaces have inclinations such that the tread edges shift axially outwards as the tread portion is worn off. The tread rubber includes a radially outermost first rubber layer and a radially inner second rubber layer. The loss tangent δ2 of the second rubber layer is larger than the loss tangent δ1 of the first rubber layer. One of or each of the buttress surfaces is provided with an outer lateral groove. The outer lateral groove is located axially outside the tread edge when the tire is new, and when the tread portion is worn off and the tread edge shifts axially outward, the outer lateral groove is at least partially located axially inward of the tread edge.
