Tread rubber composition for car tire improved abrasion property

摘要

The present invention particularly relates to the wear resistance than the tread rubber composition for excellent wear performance car tires excellent isoprene (isoprene) relates to a tread rubber composition for a car tire that can improve the wear resistance by using a rubber -containing styrene -butadiene rubber as a raw material . ; the present invention is a tread rubber composition for a car tire in , the raw material for the rubber -containing styrene- isoprene -butadiene rubber in 100 parts by weight of 20 to 60 parts by weight of the raw material comprises rubber . ; is part of the raw material rubber in the present invention is a styrene- isoprene -butadiene rubber containing isoprene contains 40~60%.
