摘要 |
The present invention relates to a tire having as a member, a rubber composition comprising (a) 100 mass parts of a rubber component comprising at least one selected from a natural rubber and a diene base synthetic rubber, (b) silica having a nitrogen-absorbing specific surface area (N2SA) of 180 to 270 m2/g and 0.1 to 10.0 mass parts of (c) a partial ester compound of maleic anhydride and a (poly)oxypropylene derivative described above. The tire further comprises as a tread rubber, a rubber composition comprising (A) a rubber component comprising a conjugate diene base rubber, (B) a filler comprising 10 mass % or more of a white filler based on the whole fillers and (C) a partial ester compound of maleic anhydride and a (poly)oxypropylene derivative. This tire has good abrasion resistance, enhanced low heat build-up property, improved processability, excellent driving stability, good physical properties and excellent wet gripping property. |

1. An off-road tire characterized by using as a tread rubber, a rubber composition comprising (A) a rubber component comprising a conjugate diene base rubber, (B) a filler comprising 10 mass % or more of silica based on the total amount of filler, (C) a partial ester compound selected from the group consisting of mono[POP(5) lauryl ether] maleic acid ester, mono[POP(5) myristyl ether] maleic acid ester and mono[POP(5) 2-ethylhexyl ether] maleic acid ester, and (D) a petroleum base resin having a softening point of 30 to 150° C. and an α-olefin base resin,
wherein the conjugate diene base rubber comprises at least a styrene-butadiene copolymer rubber. |
