Pneumatic tire having a cast body of viscoelastic material, a carbon black-reinforced rubber tread (11) and a girdle member (17). The cast body is continuous and extends from one bead area to the other encompassing the entire sidewalls of the tire and a crown portion (14) radially inward of the rubber tread. The girdle member is contiguous with the crown portion of the cast body, is comprised of a layer of circumferential cords, has a Poisson's ratio substantially equal to the Poisson's ratio of the crown portion of the cast body contiguous to it and a modulus greater than the modulus of the crown portion of the cast body contiguous to it. The girdle may be totally embedded in the crown portion of the cast body or it may be located at the junction of the crown portion of the cast body and the rubber tread. An adhesive is provided at the interface of the cast body and the rubber tread to facilitate adhesion.
