PROBLEM TO BE SOLVED: To provide an additive for inorganic filler-compounded rubber and a rubber composition, which provides a tire with good operation stability on a dry road surface and excellent low rolling resistance, and to provide a tire using the rubber composition as a component.SOLUTION: Provided are an additive for inorganic filler-compounded rubber and a rubber composition containing a compound represented by the following general formula (1), and to provide a tire using the rubber composition as a component. [In the formula, A, A, and Aeach independently represent a sulfur-containing functional group; Rto Reach independently represent an alkoxy group; and X's each independently represent -O-(R-O-), where Rrepresents an alkanediyl group or an alkenediyl group having 2 to 18 carbon atoms, and the plurality of Rmay be the same or different; and r represents the average number of moles of addition ranging from 1 to 31; and n is on average 0 to 10.]

【課題】タイヤに乾燥路面での良好な操縦安定性、且つ優れた低転がり抵抗を付与しうる無機充填材配合ゴム用添加剤及びゴム組成物、並びにそのゴム組成物を部材として用いたタイヤを提供すること。【解決手段】下記の一般式（１）で表される化合物を含む無機充填材配合ゴム用添加剤及びゴム組成物、並びにそのゴム組成物を部材として用いたタイヤである。［式中、Ａ1、Ａ2及びＡ3はそれぞれ独立して硫黄含有官能基を、Ｒ1乃至Ｒ5はそれぞれ独立してアルコキシ基を、Ｘはそれぞれ独立して−Ｏ−（Ｒ6−Ｏ−）rを表す。ここで、Ｒ6は炭素数２〜１８の、アルカンジイル基又はアルケンジイル基を表し、複数のＲ6は同じでも異なっていてもよい。ｒは平均付加モル数で１〜３１の数を表す。ｎは平均で０〜１０である。］【選択図】なし
