WIPO Patent Application WO/2022/202698
Kind Code:
A1
Abstract:
This rubber composition for tires comprises a diene-based rubber, carbon black, and recycled carbon black, wherein the carbon black has a nitrogen-adsorption specific surface area N2SA of 30-90 m2/g and a DBP oil absorption of 70-140 ml/100 g, the recycled carbon black has a nitrogen-adsorption specific surface area N2SA of 65-95 m2/g and a DBP oil absorption of 75-105 ml/100 g, the total carbon black amount, which is the sum of the carbon black and the recycled carbon black, is 30-130 parts by mass per 100 parts by mass of the diene-based rubber, and the proportion of the recycled carbon black in the total carbon black amount is 3-30 mass%.
