Publication number: 20240001718Abstract: A two-wheeled vehicle tire for running on rough terrain, the tire comprising a tread portion. The tread portion comprises a plurality of middle blocks located between a tire equator and a tread edge. The plurality of middle blocks comprises at least one first middle block having an outer surface in a tire radial direction, and at least one second middle block having an outer surface in the tire radial direction whose area is larger than an area of the outer surface of the at least one first middle block. The outer surface in the tire radial direction of the at least one first middle block is not provided with sipes. The outer surface of the at least one second middle block is provided with at least one sipe.Type: ApplicationFiled: June 16, 2023Publication date: January 4, 2024Applicant: Sumitomo Rubber Industries, Ltd.Inventor: Yukiko HINAMI

Publication number: 20240001717Abstract: A two-wheeled vehicle tire for running on rough terrain includes a tread portion having a designated rotation direction. The tread portion includes at least one first block. The first block includes a pair of block pieces adjacent to each other in the tire axial direction, and a tie-bar connecting the block pieces. The tie-bar has an outer surface in the tire radial direction, and the outer surface of the tie-bar has a height increasing toward the trailing side in the rotation direction. The pair of block pieces each has an outer surface in the tire radial direction, and the outer surface of each block piece has an axially extending leading edge located on the leading side thereof. The leading edge of each block piece is inclined toward the trailing side in the rotation direction from the end on the tie-bar side outwardly in a block-width direction.Type: ApplicationFiled: June 16, 2023Publication date: January 4, 2024Applicant: Sumitomo Rubber Industries, Ltd.Inventor: Yukiko HINAMI

Patent number: 11697313Abstract: A tyre for running on rough terrain has a tread portion including a plurality of blocks and tread crossing grooves extending between a first tread edge and a second tread edge without intersecting the blocks. Each of the tread crossing grooves includes a soil discharging space having a width of at least 10 mm or more and extending linearly so as to connect between the first tread edge and the second tread edge. The soil discharging space is inclined at an angle of 30 degrees or more and 50 degrees or less with respect to a tyre axial direction.Type: GrantFiled: July 17, 2019Date of Patent: July 11, 2023Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Yukiko Hinami

Publication number: 20230104245Abstract: A tire for running on rough terrain for which an intended tire rotational direction is specified. The tread portion is provided with blocks raised from a tread base portion. Each block has a first side wall surface comprising a radially outer portion extending substantially straight and radially inwardly, while inclining toward the toe side in the intended tire rotational direction, and a radially inner portion extending from the radially outer portion to the tread base portion while curving in an arc shape. The radially outer portion has a radial length of from 30% to 70% of a radial height of the block.Type: ApplicationFiled: October 3, 2022Publication date: April 6, 2023Applicant: Sumitomo Rubber Industries, Ltd.Inventor: Yukiko HINAMI

Patent number: 11427034Abstract: A tire includes a tread portion including a tire equator, a tread edge located axially outwardly of the tire equator, and at least one block. The at least one block includes a ground contact top surface having an axially extending first edge, and a first sidewall surface extending radially inwardly from the first edge. The first sidewall surface includes an axially inner portion located on the tire equator side and an axially outer portion located on the tread edge side. A maximum inclined angle of the inner portion with respect to a tire normal is greater than a maximum inclined angle of the outer portion with respect to a tire normal.Type: GrantFiled: August 1, 2018Date of Patent: August 30, 2022Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Yukiko Hinami
