Abstract
A rubber composition contains (A) a modified conjugated diene-based polymer, (B) modified silica, and (C) a polymer having crystalline character. A crosslinked product is produced through crosslinking of the rubber composition containing the modified conjugated diene-based polymer (A), the modified silica (B), and the polymer having crystalline character (C). The crosslinked product is used for producing a tire including a tread and a sidewall, wherein at least one of the tread and the sidewall is formed of the crosslinked product.
