A rubber composition for tires which comprises 100 parts by weight of a rubber, 1-30 parts by weight of a polyether (E1) represented by the formula (I): R1-{(OCH2CH2CH2CH2)m(OA)n-OH}q (I) (wherein R1 is a residue formed by removing at least one hydroxy group from a C1-24 compound having one to six hydroxy groups; A is C2-24 alkylene excluding 1,4-butylene; q is an integer of 1-6; and m and n each independently is an integer of 1-600) and/or a derivative thereof (E2), and 10-180 parts by weight of a filler. The composition is excellent in processability, silica dispersion, wearing resistance, wet braking performance, etc. |
