Abstract: A pneumatic tire has a belt arranged in such a manner that cords are inclined with respect to a tire circumferential direction. A quarter portion is set to a portion which is between 50 to 80% of a belt width around a tire equator line, a center portion is set to a portion which is inside than the quarter portion, and a shoulder portion is set to a portion which is outside than the quarter portion. A relation ?c>?s>?q is satisfied on the assumption that a cord angle in the quarter portion is set to ?q, a cord angle in the center portion is set to ?c, and a cord angle in the shoulder portion is set to ?s, with regard to the cord angle of the belt with respect to the tire circumferential direction.

Abstract: A pneumatic tire provided with a pair of bead cores, a troidal-shaped carcass surrounding said bead cores, a tread rubber, a carcass, a plurality of belt layers reinforced by steel cords, wherein in at least one of said belt layers, the maximum value of deviation of an angle ?c of said steel cords is not greater than 3 degrees with respect to the angle made by said steel cords at the center in the tire width direction and the tire circumferential direction.
