发明名称 ゴム組成物及び空気入りタイヤ
摘要 PROBLEM TO BE SOLVED: To provide a rubber composition capable of simultaneously improving rolling resistance performance and wet performance of a tire.SOLUTION: The rubber composition comprises 100 parts by mass of the following rubber component and 5 to 150 parts by mass of filler. The rubber component comprises a modified diene-based rubber having at least one connecting group selected from a group of connecting groups expressed by formulae (1) to (4) below in the molecule, and having such a structure that diene-based polymer chains including a hydroxyl group directly connected to the main chain are connected by the above connecting group. The connecting groups are expressed by (1):R-C(=O)-CH=CH-R, (2):R-C(=O)-CH-CH(OH)-R, (3):R-CH(CHO)-CH(OH)-R, and (3):R-C(CHO)=CH-R.
