Patent number: 10093132Abstract: A pneumatic tire (1) has a tread (2), the direction (R) of rotation of the tread (2) being specified. Crown main grooves (3) and shoulder main grooves (4) are provided in the tread (2) to thereby define middle lands (5B). Each of the middle lands (5B) is provided with middle lateral grooves (18) arranged in separating from each other so as to define middle blocks (20). Each of the middle blocks (20) is provided with: a middle narrow groove (21) which extends from a middle lateral groove (18) on the trailing landing side, in the direction (R) of rotation, toward the leading landing side and which terminates without reaching a middle lateral groove (18) on the leading landing side; an inner sipe (S2) disposed on the inside of the middle narrow groove (21) in the axial direction of the tire; and an outer sipe (S3) disposed on the outside in the axial direction of the tire.Type: GrantFiled: July 7, 2014Date of Patent: October 9, 2018Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Yukishi Yoshida

Patent number: 10005322Abstract: This pneumatic tire is provided with a center land section demarcated between a pair of center primary grooves extending in a zig-zag shape at a tread section. The center land section is provided with: one center narrow groove extending contiguously in a zig-zag manner in the peripheral direction of the tire at the tire equator; and a plurality of center lug grooves that traverse the center narrow groove from the center primary groove and have a terminus positioned within the center land section. The center lug grooves have: a primary groove section extending from the center primary groove to an apex of the zig-zag of the center narrow groove, and is inclined to one side with respect to the axial direction of the tire; and a sub-groove section extending from an apex of the zig-zag to the terminus and inclined in the reverse direction from the primary groove section.Type: GrantFiled: July 8, 2014Date of Patent: June 26, 2018Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Yukishi Yoshida
