エアレスタイヤ
Document Type and Number:
Japanese Patent JP6467241
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an airless tire which reduces a rolling resistance while securing superior steering stability performance.SOLUTION: An airless tire 1 couples a tread ring 2 and a hub 3 by means of a radial spoke 4. Therein, the tread ring 2 includes first and second reinforcing cord layers 5, 6 arranged on inner and outer parts in a radial direction and a shear rubber layer 7 disposed between them. Ratios Eb/Ee, Eb/Ee of tensile moduli Eb, Ebin a tire circumferential direction of the first and second reinforcing cord layers 5, 6 to shear modulus Ee of the shear rubber layer 7 are respectively 100 or more. The shear rubber layer 7 has a loss tangent tanδ of 0.06 or less and a ratio Ee/tanδ of 1500 or more (unit MPa).SELECTED DRAWING: Figure 3
