To provide a rubber composition usable for a layered member of a tire, which can achieve both good hardness and elongation.SOLUTION: The rubber composition for tire fiber coating contains a diene rubber and a resin. The diene rubber contains a natural rubber and a styrene-butadiene rubber. The proportion of the natural rubber in the diene rubber is 30 mass% or more and 70 mass% or less. The proportion of the styrene-butadiene rubber in the diene rubber is 30 mass% or more and 70 mass% or less. The content of the resin is 40 pts.mass or more based on 100 pts.mass of the diene rubber.SELECTED DRAWING: Figure 1
