Light tire bodies using thick cords |
| 摘要 |
A light tire body using thick cords is disclosed. The tire body comprises a bias-structured carcass composed of rubberized plies each including thick organic fiber cords. The rubber between the carcass plies has a thickness corresponding to hm/ho</=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 prepared from a compounding recipe of at least one rubber ingredient selected from natural rubber and diene rubbers, a softener, an organic vulcanization accelerator and sulfur as well as at least 30 wt.% of carbon black having an average iodine adsorption value of 40-90 mg/g and an average DBP absorption value of 60-140 ml/100 g, and has a dynamic modulus of elasticity E' at 100 DEG C. under 2% elongation given by E'>/=6.0x107 dyne/cm2, a dynamic loss angle tan delta given by tan delta </=0.095 and a tensile strength of not less than 100 kg/cm2 as properties after vulcanization.
