| 20160083567 | RUBBER COMPOSITION WITH HIGH PROCESSABILITY FOR RUN-FLAT TIRE - The crosslinkable rubber composition comprises a first elastomer consisting of polybutadiene having a Mooney plasticity ranging from 40 to 70 Mooney units, the content of the first elastomer being strictly greater than 50 phr, a second elastomer, and a carbon black having a specific surface area within a range of values extending from 15 m | 03-24-2016 |
| 20160107489 | RUN FLAT TIRE - We provide a run flat tire capable of ensuring high resistance to coming off of a bead portion from a rim in run flat running, while maintaining high durability of a side-reinforcing rubber. Specifically, a run flat tire, has a tread portion, a pair of sidewall portions continuous with respective sides of the tread portion, bead portions continuous with the respective sidewall portions, and a side-reinforcing rubber having a crescent-shaped cross section and provided in each sidewall portion, wherein in a cross section in the tire width direction thereof: diameter of a circle collectively formed by the bead heal point is smaller by 1.7-2.9 mm than rim diameter of a prescribed rim; and a line linking the bead heal point and the bead toe point of the bead portion is inclined by an angle of 12.2°-14.7° with respect to the tire width direction. | 04-21-2016 |
| 20160121662 | RUN FLAT TIRE - We provide a run flat tire capable of ensuring high resistance to coming off of a bead portion from a rim in run flat running, while maintaining high durability of a side-reinforcing rubber. Specifically, a run flat tire, has a tread portion, a pair of sidewall portions continuous with respective sides of the tread portion, bead portions continuous with the respective sidewall portions, bead cores each embedded in the corresponding bead portion, and a side-reinforcing rubber having a crescent-shaped cross section and provided in each sidewall portion, wherein in a cross section in the tire width direction thereof: diameter of an annular inner end in the tire radial direction of the bead core is larger by 3.0-4.5 mm than rim diameter of a prescribed rim; and diameter of a circle collectively formed by the bead heal point is smaller by 1.7-2.9 mm than the rim diameter of the prescribed rim. | 05-05-2016 |
| 20160121664 | RUN-FLAT TIRE - A run-flat tire ensures run-flat durability with a reduced weight. A tire radial outermost carcass ply of two or more carcass plies has tire widthwise inner ends in a crown portion. A bead filler and side reinforcing rubber have an overlapping part in the tire width direction. In a cross section of the run-flat tire in the tire width direction in a state where the run-flat tire is attached to an applicable rim, filled to a specified internal pressure, and placed under no load, a thickness d1 of a sidewall portion at a midpoint in the tire radial direction between a maximum width position of the run-flat tire and a tire radial outermost position of a bead core is greater than a thickness d2 of the sidewall portion at a midpoint in the tire radial direction between the maximum width position of the run-flat tire and a tread edge. | 05-05-2016 |
| 20160144670 | RUN-FLAT TIRE - A tire includes: bead cores; a carcass; a bead filler that extends along an outer face of the carcass from the bead core toward a tire radial direction outer side; and side reinforcing rubber that is provided at a tire side portion that extends in the tire radial direction along an inner face of the carcass, that decreases in thickness on progression toward the bead core side and toward a tread portion side, that has an end portion at the bead core side that overlaps with bead filler with the carcass sandwiched therebetween, and that has an elongation at break of 130% or above, wherein a thickness of the side reinforcing rubber at a midpoint between an end portion at the tire radial direction outer side of the bead filler running along the carcass, and the end portion is 40% to 80% of a maximum thickness. | 05-26-2016 |
