text: In a conventional radial tire using a relatively low elastic cord as a belt layer a width of a main portion of a crown reinforcing ply layer is equal to a ground-contacting width, and belt layers which are adjacent to each other inner side and outer side in the radial direction of the tire are laminated on one another with extremely small steps interposed therebetween in most of cases (see JP-A No. 5-193306 ).
text: According to one aspect of the present invention, a pneumatic radial tyre comprises a toroidal carcass ply, a breaker belt disposed radially outside the carcass ply, and a band belt disposed radially outside the breaker belt, characterised by the breaker belt comprising at least one ply of parallel non-metallic cords, the band belt comprising a ply of at least one hybrid cord wound spirally and continuously in the circumferential direction of the tyre at an angle of 0 to 3 degrees with respect to the tyre equator, the hybrid cord comprising a low elastic modulus thread and a high elastic modulus thread which are final-twisted together, the low elastic modulus thread comprising at least one low elastic modulus fibre first-twisted and having an elastic modulus of not more than 2000 kgf/sq.mm, the high elastic modulus thread comprising at least one high elastic modulus fibre first-twisted and having an elastic modulus of not less than 3000 kgf/sq.mm, in the band belt ply, the count (E) of the hybrid cord per 5cm width, the stress (F1) in kgf of the hybrid cord at 2% elongation, and the stress (F2) in kgf of the hybrid cord at 6% elongation satisfying the following relationships:and
