摘要： A thick-cord lightweight tire body having an improved fatigue life is disclosed. The tire body comprises a bias-structured carcass composed of rubberized plies each including thick organic fiber cords and rubber interposed between the carcass plies. The rubber has a thickness corresponding to hm/ho.ltoreq.0.5, where hm is an average rubber gauge between the plies at a center position in a widthwise direction of tire and, ho is a diameter of the thick cord, and is a rubber composition consisting essentially of 100 parts by weight of a rubber component and 50-70 parts by weight of carbon black. The rubber component is a mixture of 60-95 parts by weight of a rubber and 5-40 parts by weight of a liquid polymer having a viscosity-average molecular weight of 3.times.10.sup.4 -10.times.10.sup.4. The rubber composition has a dynamic modulus of elasticity E' at 100.degree. C. under 2% elongation given by E'.gtoreq.6.0.times.10.sup.7 dyne/cm.sup.2, a dynamic loss angle tan .delta. given by tan .delta..ltoreq.0.095 and a tensile strength of not less than 100 kg/cm.sup.2 as properties after vulcanization.
