摘要： In a pneumatic tire of the type which consists of a pair of right and left beads, a pair of right and left side walls continuing the beads, respectively, and a tread interposed between the side walls, and in which a carcass cord layer is spread between the beads, and at least two layers consisting of a belt reinforcing layer whose reinforcing cords have a cord angle of from 15.degree. to 30.degree. with respect to the circumferential direction of the tire and a belt reinforcing layer whose reinforcing cords have a cord angle of from 150.degree. to 165.degree. with respect to the tire circumferential direction, and laminated and disposed between the tread and the carcass cord layer, a pneumatic tire for a passenger car characterized in that the carcass cord layer has a two-layered laminate structure consisting of upper and lower carcass cord layers; the angle of the reinforcing cords constituting each of the carcass cord layers with respect to the tire circumferential direction, when measured from the side in which the angle of the reinforcing cords of the belt reinforcing layer on the contact side with the carcass cord layer describes an acute angle with respect to the tire circumferential direction, is such that the mean value 1/2(.alpha..sub.1 +.alpha..sub.2) of the angle .alpha..sub.2 of the reinforcing cords of the carcass cord on the contact side with the belt reinforcing layer and the angle .alpha..sub.1 of the reinforcing cords of the carcass cord layer below the former is from 96.degree. to 108.degree. and their difference (.alpha..sub.2 -.alpha..sub.1) is from 10.degree. to 40.degree.; the upper carcass cord layer consists of polyester while the lower carcass cord layer consists of nylon; both ends of the upper carcass cord layer are extended from the ends of the belt reinforcing layers to the bead wires of the beads while both ends of the lower carcass cord layer are turned up from inside to outside by the bead wires; and the surface creep distance x of the upper carcass cord layer from the end of the belt reinforcing layer to the end thereof and the surface creep distance l of the lower carcass cord layer from the end of the belt reinforcing layer to the upper end of the bead wire satisfy the relation x/l=0.2.about.0.9.

摘要： A pneumatic tire is disclosed which comprises a tread, a carcass cord layer and at least two belt reinforcing layers disposed between the tread and the carcass cord layer, wherein the reinforcing cord of one of the belt reinforcing layers has an angle of 15.degree. to 30.degree. with respect to the circumferential direction of the tire and the reinforcing cord of the other makes an angle of 150.degree. to 165.degree. to the circumferential direction. The carcass cord layer consists of only one layer and the reinforcing cord thereof makes an angle of 66.degree. to 82.degree. with respect to the circumferential direction of the tire.
