Abstract
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.
