Patent number: 7543616Abstract: A heavy duty tire has a tread portion 2 which is divided into five inner, intermediate and outer rib-like land portions R1, R2, R2, R3 and R3. The inner rib-like land portion R1 is virtudally divided into half regions R1a and R1a on each side of a tire equator. The intermediate rib-like land portions R2 and R3 are virtually divided into tire equator-side half regions R2c and R3c, and into ground-contact edge-side half regions R2e and R3e. In a regular ground-contact state in which a normal load is applied, when total sums of ground-contact load applied to the half regions R1a, R2c, R2e, R3c and R3e are defined as P1a, P2c, P2e, P3c and P3e, P2c/P1a is set to 0.9 to 1.05, P2e/P2c is set to 0.75 to 1.0, P3c/P2e is set to 0.9 to 1.2, and P3e/P3c is set to 0.8 to 1.1.Type: GrantFiled: December 13, 2002Date of Patent: June 9, 2009Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Kiyoto Maruoka, Minoru Nishi, Atsushi Yamahira, Takahiro Kimishima, Satoshi Tsuda

Patent number: 7469731Abstract: In a ground-contact surface shape of a tire, when a tangent angle formed between an axial direction of the tire and a tangent X at each point P on a profile line of the tire is defined as ?, a tangent angle ?1 in a ground-contact end point Pd is 25° or smaller. When a minimum value of the tangent angle ? in a region Y which is separated away from a tire equator C by a distance in a range of not less than 0.4 times but not more than 0.7 times a half of the ground-contact width of the tread is defined as ?2, and a tangent angle at a 0.9 times point Pq which is separated away from the tire equator C by a distance of 0.9 times the half of the ground-contact width of the tread is defined as ?3, a difference (?3??2) is set in a range of not less than ?10° but not more than +10°.Type: GrantFiled: December 16, 2002Date of Patent: December 30, 2008Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Takeshi Kuroki, Minoru Nishi, Takahiro Kimishima, Satoshi Tsuda, Jyunji Ohira, Mitsuharu Koya, Masakazu Washizuka

Publication number: 20070144650Abstract: The heavy duty tire comprises a belt layer 7 comprised of at least three belt plies outside of a carcass 6 in a radial direction. Belt cords of a first belt ply 7A disposed innermost in the radial direction incline at an angle of 45 to 55 degrees with respect to a tire equator C. Belt cords of second and third belt plies 7B, 7C disposed outside thereof incline at an angle of 16 to 22 degrees with respect to the tire equator C and into mutually opposite directions. Width BW3 of the third belt ply 7C is smaller than width BW2 of the second belt ply 7B and is also 77 to 95% of a tread grounding width TW. Width BW1 of the first belt ply 7A is smaller than the width BW3 of the third belt ply 7C by 20 to 35 mm. An inter-cord distance S between the first belt ply 7A and the carcass ply 6A in the tire radial direction is 0.8 to 1.2 mm.Type: ApplicationFiled: October 24, 2006Publication date: June 28, 2007Inventor: Satoshi Tsuda

Patent number: 7128111Abstract: A pneumatic tire which comprises a tread portion with a pair of tread edges, and a tire shoulder extending radially inwardly from one of the tread edges, provided with a curved surface comprising a convex curve, wherein, on a cylindrical surface centered on the tire axis and intersecting the curved surface, the convex curve swells axially outwards and has a curvature, and the curvature gradually diminishes towards the radially inside from the tread edge. It is possible that the tread portion is provided along the tread edges with a circumferentially extending rib and/or a circumferential row of blocks. In case of circumferential rib, the rib is provided with the curved surface comprising a plurality of the convex curves and a plurality of convex curves alternating therewith so that the curved surface is waved in the tire circumferential direction. In case of blocks in a circumferential row, it is preferable that each block is provided with the curved surface comprising at last one convex curve.Type: GrantFiled: December 23, 2003Date of Patent: October 31, 2006Assignee: Sumitomo Rubber Industries, Ltd.Inventor: Satoshi Tsuda

Patent number: 7093630Abstract: A heavy duty radial tire which is provided with traverse grooves extending between the tread edges and longitudinal grooves extending between the traverse grooves so as to form shoulder blocks arranged along each of the tread edges and inner blocks each disposed on the axially inside of one of the shoulder blocks. The longitudinal grooves between the shoulder blocks and the inner blocks have a depth Dga of 0.7 to 1.0 times the depth Dy of the traverse grooves, and the longitudinal grooves are each inclined at an acute angle with respect to the circumferential direction to have an axial extent range Y whose axial width W1 is in a range of from 1.0 to 10.0 times the width Wga. In a cross section of the tire under a normally inflated unloaded condition, the tread profile is made up of a center profile Si and a shoulder profile So. The shoulder profile So extends continuously from each of the axial ends of the center profile Si through an inflection point P to one of the tread edges.Type: GrantFiled: December 23, 2003Date of Patent: August 22, 2006Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Takahiro Kimishima, Satoshi Tsuda, Minoru Nishi
