Abstract: As the present invention there is disclosed a pneumatic radial tire comprising a carcass having a smaller tensile rigidity than that of conventional pneumatic radial tires by application of a steel cord having a smaller Young's modulus to the carcass or by application of a smaller amount of a high strength steel cord formed with carcass filaments having a greater tensile strength to the carcass while maintaining the necessary strength of the carcass. In accordance with the present invention, extension of the carcass increases and extension of a belt in the circumferential direction of the tire is suppressed when the tire is inflated by an inner pressure. As a result, compression stress working on the carcass when a vehicle turns decreases and buckling deformation of the steel cord can be prevented. Accordingly, durability is improved. The amount of the cord required to maintain the strength of the carcass can be decreased by application of the high strength steel cord, thereby decreasing weight of the tire.

Abstract translation: 作为本发明，公开了一种充气子午线轮胎，其包括具有比常规充气子午线轮胎更小的拉伸刚度的胎体，其通过向胎体施加具有较小杨氏模量的钢帘线或通过施加较小量的高 强度钢帘线形成有与胎体相比具有更大拉伸强度的胎体长丝，同时保持胎体的必要强度。 根据本发明，当通过内压使轮胎膨胀时，胎体的延伸增加并且在轮胎的圆周方向上的带的伸长被抑制。 结果，可以防止车辆转弯时对胎体的压缩应力减小，并且可以防止钢帘线的翘曲变形。 因此，耐久性提高。 通过施加高强度钢丝绳可以减少维持胎体强度所需的帘线的量，从而减轻轮胎的重量。
