Abstract
There is a tire having tire performances such as wear resistance, cut resistance, heat build-up and the like and a processability simultaneously and economically improved by the application of a rubber composition containing a rubbery polymer modified with a silane compound and silica. The rubbery polymer modified with the silane compound is obtained by reacting an active terminal of a living polymer, which is obtained by polymerizing a monomer in the presence of an organic alkali metal catalyst, with a silane compound represented by the following general formula: EQU X.sub.n Si(OR).sub.m R'.sub.4-m-n (where X is a halogen atom selected from a chlorine atom, a bromine atom and an iodine atom, OR is a non-hydrolyzable alkoxy group having a carbon number of 4.about.20, an aryloxy group or a cycloalkoxy group, R' is an alkyl group having a carbon number of 1.about.20, an aryl group, a vinyl group or a halogenated alkyl group, m is an integer of 1.about.4, n is an integer of 0.about.2, and a sum of n and m is 2.about.4), which is contained in an amount of not less than 10% by weight as a rubber ingredient, and silica is contained in an amount of 5.about.200 parts by weight based on 100…
