Abstract:
The rubber composition for a tread comprises: 5 to 30 parts by mass of a carbon black, 95 parts by mass or more of silica, 25 parts by mass or more of a powder of an inorganic compound represented by a given formula (A) and having an average primary particle size of 10 μm or less, and 70 parts by mass or more of a softening agent comprising 2 to 15 parts by mass of a coumarone-based resin, based on 100 parts by mass of a rubber component comprising 70% by mass or more of a styrene-butadiene rubber having a styrene content of from 20 to 50% by mass and a vinyl content of from 15 to 65%, and the tire has a tread composed of the rubber composition for a tread.

Claim (Index 1):
A rubber composition for a tread comprising:\n 5 to 30 parts by mass of a carbon black, 95 parts by mass or more of silica, 25 parts by mass or more of a powder of an inorganic compound represented by the following formula (A) and having an average primary particle size of 10 \u03bcm or less, and 70 parts by mass or more of a softening agent comprising 2 to 15 parts by mass of a coumarone-based resin, based on 100 parts by mass of a rubber component comprising 70% by mass or more of a styrene-butadiene rubber having a styrene content of from 20 to 50% by mass and a vinyl content of from 15 to 65%,\n M.\u03b1SiO 2 .\u03b2H 2 O\u2003\u2003(A) \n (In the formula, M is an oxide or hydroxide of at least one metal selected from Al, Mg, Ti and Ca, and each of \u03b1 and \u03b2 is an integer of from 0 to 10.)
