Provided are a rubber composition for tire containing raw material rubber and cellulose whiskers, and a tire produced from the same composition and having excellent general properties. Since the rubber composition for tire contains cellulose whiskers having superior reinforcing properties than rubber reinforcing materials, the rubber composition for tire can provide a tire having markedly enhanced properties compared to tires using the conventional rubber reinforcing materials. Also, when cellulose whiskers are applied to the rubber composition for tire, the content of the conventional rubber reinforcing materials can be reduced. As a result, the elongation ratio and low-fuel consumption performance that have been considered poor due to the use of conventional rubber reinforcing materials can be improved to a superior level, and a lightweight tire can be provided.
