Title:
タイヤ用ゴム組成物及びその製造方法
Document Type and Number:
Japanese Patent JP6480820
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rubber composition for tire excellent in processability when it is vulcanized, excellent in low hysteresis loss property and wet skid resistance and further having excellent abrasion resistance and breaking strength and a manufacturing method therefor.SOLUTION: The invention relates to a rubber composition for tire containing a rubber component containing a modified conjugated diene polymer, first silica and second silica having smaller average primary particle diameter than that of first silica, where the modified conjugated diene polymer has Mooney relaxation rate (MSR) measured at 110°C of 0.45 or less, modification rate of 80 mass% or more and difference between average primary particle diameter of the second silica and average primary particle diameter of the first silica of 2 nm or more.SELECTED DRAWING: None
