<p>There are provided a rubber composition for coating a steel cord, containing 100 parts by mass of diene-based rubber; 0.5 to 5 parts by mass of a metal salt of an organic acid; and 30 to 100 parts by mass of a filler, wherein the filler contains 3 to 30 parts by mass of glass beads having a particle diameter of 10 to 100 µm, relative to 100 parts by mass of the diene-based rubber, and a tire reinforcement belt and a pneumatic tire using the rubber composition. The rubber composition reduces heat generation and improves adhesiveness with a steel cord. A pneumatic tire having a tire reinforcement belt using the rubber composition has excellent steering stability and rolling resistance.</p> |
