Abstract
A method for producing a rubber composition may include: mixing modified silica (B), pre-prepared by surface treatment of unmodified silica, with a modified conjugated diene-based polymer (A) and a polymer having crystalline character (C). A crosslinked product may be produced through crosslinking a rubber composition obtained from such a method. The crosslinked product may be 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.
