Provided are a rubber composition for tires having low tan ´ at approximately 60°C and excellent breaking energy at approximately 25°C; a method for preparing the rubber composition for tires; and a tire thereof. The present invention relates to a rubber composition for tires which contains a rubber component including an isoprene-based rubber, and which has a correlation length b of 50 nm or less as determined by fitting the following Equations 1 to 6 to a scattering intensity curve I(q) obtained by X-ray scattering analysis or neutron scattering analysis: I q = A 1 + q 2 ¾ 2 + B 1 + q 2 b 2 2 + C 1 + q 2 c 2 2 ¾ < b < c A = 8 ÀN a à 2 ¾ 3 B = 4 ÀN b à 2 b 2 C = 4 ÀN c à 2 c 2 q = 4 À sin ¸ 2 » A, B, C, ¾ , b , c : fitting parameter q : scattering vector N a : number per unit volume (number/cm 3 ) of scatterers having a correlation length ¾ N b : number per unit volume (number/cm 3 ) of scatterers having a correlation length b N c : number per unit volume (number/cm 3 ) of scatterers having a correlation length c à : electron density difference (electron·(cm -3 )) between scatterers and the surrounding matrix or scattering length density difference (cm -2 ) between scatterers and the surrounding solvent ¸ : scattering angle » : wavelength of X rays or neutrons
