PROBLEM TO BE SOLVED: To provide a pneumatic tire favorable in grounding performance to a road face, improved in eccentric wear resistance, and also improved in drive stability.SOLUTION: In a pneumatic tire in which a carcass layer 4 is bridged between a pair of bead parts 3, 3, a plurality of belt layers 7 are arranged at an external peripheral side of the carcass layer 4 at a tread part 1, and at least one string of circumferential grooves 11, 12 continuing to a tire circumferential direction is arranged in a region at a single side from a tire center line CL at the tread part 1, a distance La from the tire center line CL up to a center position of the outermost circumferential groove 12 is set as 0.50×L≤La≤0.80×L with respect to a tread half-width L from the tire center line CL up to an outer end position P4 of the tread part 1, an angle &bgr; formed of a linear line L2 and a reference linear line L0 with respect to an angle α formed of a linear line L1 and the reference linear line L0 is set as 1.2×α≤&bgr;≤3.5×α, a cross point P3 is arranged outside a tire radial direction rather than a cross point P2, and a distance H between the cross point P2 and the cross point P3 in the tire radial direction is set as 0 mm<H≤3 mm. |
