Embodiment Construction
[0021] The rubber composition for tires of the present invention contains at least a rubber component and an inorganic filler. In the present invention, it is preferable to contain a diene rubber as a rubber component.
[0022] Examples of diene rubber include natural rubber (NR), polyisoprene rubber (IR), styrene-butadiene rubber (SBR), polybutadiene rubber (BR), Diene rubbers such as butadiene rubber (SPB), chloroprene rubber (CR), and nitrile rubber (NBR) can be used alone or in combination of two or more. As these exemplified diene rubbers, terminal-modified substances (for example, terminal-modified BR or terminal-modified SBR, etc.), or substances modified to impart desired characteristics (such as modified NR). In addition, for polybutadiene rubber (BR), in addition to rubber synthesized using cobalt (Co) catalyst, neodymium (Nd) catalyst, nickel (Ni) catalyst, titanium (Ti) catalyst, lithium (Li) catalyst, it is also possible to use Rubber synthesized by the polymer...
