FIELD: transportation.
SUBSTANCE: tire comprises an inner shell that consists of a rubber mix. Rubber mix for the inner shell comprises a rubber component and additives, the dynamic modulus E* (MPa) of elasticity of which and tangent tanδ of the angle of losses, measured at temperature of 70°C, initial deformation of 10% and dynamic deformation 2%, meet the formulas below (1)-(3), air impermeability ratio is not more than 12.00⋅10-14 cm3⋅cm/cm2⋅s⋅Pa and tensile strength (TS) (MPa) and tensile elongation (TE) (%), according to measurements in accordance with JIS K6251, meet the formulas below (4) and (5): Formula (1): E*/tanδ>17; Formula (2): 2.5<E*<5; Formula (3): tanδ>0.15; Formula (4): TE>450; Formula (5): TS⋅TE>10,000.
EFFECT: improved characteristics of driving stability, effective use of fuel and balance of physical properties, with preserved resistance of air permeability and durability.
