Patent number: 8028733Abstract: A green tire includes a surface layer defining a green tire surface and made up of a plurality of windings of an unvulcanized rubber tape. A part of each of the windings is exposed on the green tire surface so that the exposed part has a width of from 50% to 80% of the width W1 of the rubber tape. Each of the windings has a substantially rhomboid cross section and has one end at an acute angle corner exposed on the green tire surface and the other end at the opposing acute angle corner. An angle theta of a diagonal line of the rhomboid drawn between the one end and the other end is not more than 30 degrees with respect to a tangential line to a profile line of the green tire surface.Type: GrantFiled: December 27, 2007Date of Patent: October 4, 2011Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Masayuki Sakamoto, Toshiaki Ono, Toshiyuki Mafune, Takamichi Sagawa

Patent number: 8006732Abstract: A tire 10 has an endless decorative band 2 on a surface of a sidewall 1. The decorative band 2 has one or more first indicative sector 3 and one or more second indicative sector 4 which are arranged alternately and consecutively in the circumferential direction. The first indicative sector 3 consists of a background portion 5 which continuously leads to the sidewall portion 1 adjacent to the first indicative sector with a uniform surface roughness value, and a foreground portion 6 which is arranged in the background portion 5 and forms marks by having a surface roughness value larger than that of the background portion 5. A background portion 7 constituting a part or whole of the second indicative sector 4 has a surface rougher than any of the sidewall portion 1 and the background portion 5 of the first indicative sector 3.Type: GrantFiled: February 14, 2006Date of Patent: August 30, 2011Assignee: Bridgestone CorporationInventor: Daita Itoi

Publication number: 20100116401Abstract: A pneumatic tire has an annular bead core, a bead filler, a carcass ply rolled up in such a manner as to pinch the bead core and the bead filler, and a white rubber arranged in an outer side of the carcass ply of the side wall portion. The white rubber has an inner peripheral end positioned in an outer side of the bead filler. The bead filler has a main body rubber portion running into the bead core from a leading end, and a soft rubber portion constructing a part of an outer surface of the bead filler and positioned in an inner side of the inner peripheral end of the white rubber. The soft rubber portion is harder than the white rubber and softer than the main body rubber portion.Type: ApplicationFiled: September 9, 2009Publication date: May 13, 2010Applicant: Toyo Tire & Rubber Co., Ltd.Inventor: Makoto Yoshikawa
