Title:
TIRE WITH SILICA REINFORCED TREAD
Document Type and Number:
Japanese Patent JP3655702
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a pneumatic rubber tire which has well-balanced in tread properties chiefly of rolling resistance, traction and abrasion-resistance by having a tread which is quantitatively composed of a fixed content of specific elastomers, silica and a silica coupler, respectively.
SOLUTION: A pneumatic tire having a tread comprised of, based on 100 parts by weight rubber: elastomers composed of about 15 to about 40 phr of styrene/butadiene copolymer rubber prepared by solution polymerization; composed of about 85 to about 60 phr of two diene-based elastomers consisting essentially of about 10 to about 30 phr of cis 1,4-polybutadiene rubber, and about 30 to about 60 phr of high vinyl polybutadiene rubber having a vinyl content in a range of about 50 to about 90; about 55 to about 90 phr of particle silica; and at least one silica coupler having a silane moiety reactive with the surface of the silica and a sulfur moiety interactive with the elastomer, in a weight ratio of the silica to the coupler of about 7/1 to about 15/1.
