Application Number: JP,2022-060264
Category (FI): B60C7/00@H,B60C9/26@C,B60C9/26@B,B60C19/00@J,B60C9/20@E,B60C9/00@A,B60C9/00@H,B60C1/00@Z
Stage: PROBLEM TO BE SOLVED: To improve processability and load bearing property at high temperature.SOLUTION: A non-pneumatic tire comprises a spoke structure 2 in which an outer peripheral wheel 3 and an inner peripheral wheel 4 are connected to each other by a spoke 5, and a tread ring 1 arranged on the outer periphery of the outer peripheral wheel 3 in the spoke structure 2. The spoke structure 2 is at least partially arranged intermittently and at least partially composed of a high polymeric material made by hardening liquid whose viscosity at a shear rate of 10 s-1 at 80degC is 1 mPa s to 105 mPa s, and whose viscosity at a shear rate of 1 s-1 is 1 mPa s to 105 mPa s. The value obtained by dividing the viscosity at a shear rate of 1 s-1 at 80degC by the viscosity at a shear rate of 10 s-1 is 1.0 to 5.0, and the Vicat softening temperature is 80degC or more.SELECTED DRAWING: Figure 1 (Grant)
