Patent number: 10071600Abstract: A tire for a motorbike can improve turning performance and dry grip performance with good balance. In a tire for a motorbike, a tread part is provided with a first inclined groove and a second inclined groove disposed closer to a tread end than is the first inclined groove. The first inclined groove is provided to a forward-movement grounded area. An inner end of the second inclined groove is provided in an area within a range 2% of a tread expansion radius centered about an end edge of the forward-movement grounded area. An outer end of the second inclined groove is provided to a position displaced from the inner end of the second inclined groove toward the tread end by an interval 20%-30% of the tread expansion radius.Type: GrantFiled: July 1, 2014Date of Patent: September 11, 2018Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Kouji Takenaka

Patent number: 10035381Abstract: Motor vehicle tyre adapted to be mounted on the rear wheel of a motor vehicle, includes a tread band having a tread pattern including a module which is repeated along a direction of circumferential extension of the tyre. The module has at least one first pair of first grooves inclined in opposite directions with respect to an equatorial plane of the tyre, and extending from the equatorial plane toward a respective shoulder; at least one second pair of second grooves inclined in opposite directions with respect to the equatorial plane and extending from the equatorial plane toward a respective shoulder. The first and the second grooves are staggered relative to each other in the circumferential direction in such a way as to maintain a substantially constant distance of less than half the pitch, at the equatorial plane between each first or second groove and the adjacent one in the circumferential direction.Type: GrantFiled: July 28, 2010Date of Patent: July 31, 2018Assignee: PIRELLI TYRE S.P.A.Inventors: Andrea Schiavolin, Mario Mariani, Pierangelo Misani

Patent number: 9738119Abstract: A motorcycle tyre has a tread band including a central portion and two shoulder portions arranged at axially opposite sides of the central portion. The central portion includes a first plurality of grooves extended according to a substantially longitudinal direction and alternatively arranged at opposite sides of the equatorial plane of the tyre. Each groove of the first plurality of grooves has a substantially curvilinear course such as to form a concavity. The central portion further includes a sub-portion substantially free of grooves placed astride the equatorial plane of the tyre. Each of the shoulder portions includes a second plurality of grooves arranged obliquely relative to the equatorial plane of the tyre.Type: GrantFiled: December 23, 2010Date of Patent: August 22, 2017Assignee: PIRELLI TYRE S.P.A.Inventors: Mario Mariani, Sandro Gallo, Andrea Schiavolin, Pierangelo Misani

Patent number: 9573424Abstract: A motorcycle tire is provided with crown main oblique grooves disposed on alternating sides of the tire equator and each extending from its axially inner end to its axially outer end, without cutting across the tire equator, while inclining to one circumferential direction, wherein the axially outer end is located outside an upstanding tire's ground contact annular zone. When measured in the annular zone, the circumferential distance between the circumferentially adjacent crown main oblique grooves existing on the same side of the tire equator is in a range of not more than 0.5 times an upstanding tire's ground contact length. In the annular zone, the crown main oblique grooves on one side of the tire equator is partially overlaps those on the other side. When measured in the annular zone, the circumferential length of the crown main oblique groove is less than the upstanding tire's ground contact length.Type: GrantFiled: November 8, 2013Date of Patent: February 21, 2017Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Takao Kuwahara
