PROBLEM TO BE SOLVED: To provide a rubber composition which can allow a tire obtained therefrom to have low heat generation properties and be excellent in wet grip properties and wear resistance, to provide a rubber-crosslinked product which is obtained by crosslinking the rubber composition, and to provide another tire which is obtained by using the rubber-crosslinked product.SOLUTION: The rubber composition contains: 100 parts weight of a rubber component containing the modified conjugated diene rubber which is obtained by reacting a conjugated diene polymer chain having active terminals with a silicon compound having a functional group capable of being reacted with the active terminal thereof; and 10-200 parts weight of silica having the pH of 8-12. |
