WIPO Patent Application WO/2016/056444
Kind Code:
A1
Abstract:
[Problem] To provide a rubber composition for tires, a pneumatic tire, and an airless tire that can improve tire steering stability while exhibiting very low fuel consumption. [Solution] A rubber composition for tires, said composition characterized by having, as physical properties of vulcanized rubber, an initial strain of 10%, a dynamic strain of 2%, and, at 70°C, a complex elastic modulus E*70 (unit: MPa) and a loss tangent tanδ70 that satisfy 90800. A pneumatic tire provided with a rubber member formed from the rubber composition. An airless tire provided with a rubber member formed from the rubber composition. An airless tire in which a shear rubber layer (107) is provided to the inside of a tread ring, wherein the shear rubber layer is formed from the rubber composition.
