Title:
A rubber composition for tires, and the breaking test method
Document Type and Number:
Japanese Patent JP6259267
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rubber composition for a tire which has excellent tread break-off resistance performance.SOLUTION: A rubber composition for a tire is to be broken under a dynamic torsional amplitude of 250% or more when dynamic torsional deformation in synchronization with compressive strain is applied during dynamic compressive deformation at 70-150°C. A destruction test method for a rubber crosslinked material includes applying simultaneously combined deformation of dynamic compressive deformation and dynamic torsional deformation to a sample at 70-150°C.
