[0108] Seventy types of rubber compositions for tire treads (Examples 1 to 29, Comparative Examples 1 to 41) composed of the compounds shown in Tables 1 to 11 were prepared by mixing components other than sulfur and vulcanization accelerators with those shown in Table 12. The common compounding components shown were kneaded in a 16 L closed mixer at 150° C. for 6 minutes, sulfur and a vulcanization accelerator were added to the released masterbatch, and kneading was carried out using an open roll to prepare. In Tables 1 to 11, when the SBR contains extended oil, the compounded amount of SBR containing extended oil is described, and the compounded amount of SBR excluding the net weight of oil is described in parentheses. In addition, the amounts of the commonly compounded components shown in Table 12 are compounded in parts by weight relative to 100 parts by weight of the diene rubbers described in Tables 1 to 11 (rubber weight by net weight).
