Abstract
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.
