| 20080236714 | PNEUMATIC TIRE - Provided is a low profile pneumatic tire for an SUV, which is capable of having its enhanced rut performance with its dry and wet performances being reconciled with each other. The pneumatic tire according to the present invention has a nominal width of not less than 255, an outside diameter of not less than 720 mm, and an aspect ratio of not more than 55%. The pneumatic tire has a designated direction of sides thereof for mounting the tire on a vehicle. In its tread portion, the pneumatic tire includes five main grooves extending in the tire's circumferential direction, and six land portions defined by the five main grooves. Each of the shoulder land portions located outermost in the tire's width direction is divided into a narrow rib portion with a width of not less than 10 mm but not more than 15 mm on a side closer to its neighboring main groove and a block portion on a side closer to a corresponding one of the shoulders by a narrow groove which extends in the tire's circumferential direction, and which has a depth less than 50% of that of its neighboring main grooves. The remaining four land portions interposed between the shoulder land portions each have a depth of not less than 20 mm but not more than 26 mm. | 10-02-2008 |

| 20100108214 | TYRE FOR MOTOR VEHICLES - The tread band of a tyre has two circumferential portions, a central one and an inner intermediate one, respectively, that are subdivided into centre and intermediate blocks respectively; an inner-shoulder circumferential portion has first and second inner-shoulder cuts, axially offset from each other and distributed in an alternated sequence, to confine a continuous inner-shoulder rest surface with an undulated course; and an outer intermediate circumferential portion has first and second intermediate cuts, and an outer-shoulder circumferential portion has first and second outer-shoulder cuts. The first and second intermediate cuts and the outer-shoulder cuts, respectively, mutually converge at an angle of about 20° and are axially offset from each other and circumferentially distributed in an alternated sequence, to delimit continuous rest surfaces, an intermediate and outer-shoulder surface respectively, with an undulated course. | 05-06-2010 |

| 20130037191 | PNEUMATIC TIRE - A pneumatic tire comprising a tread portion, side wall portions, and bead portions. The tread portion of said pneumatic tire includes at least one groove unit including a main groove extending in a tire circumferential direction and an auxiliary groove extending in the tire circumferential direction that has a smaller width than that of the main groove. The main groove and/or the auxiliary groove meanders in a wave or zigzag manner, and the main groove and the auxiliary groove intersect so as to intertwine with each other. Additionally, a rib portion extending in the tire circumferential direction is disposed adjacent along the groove unit including the main groove and the auxiliary groove. | 02-14-2013 |
