摘要:
A pneumatic tire allowed to increase steering stability and durability while reducing rolling resistance, wherein a reinforced rubber layer extending from a bead part along a side wall part is installed in the side wall part. A rubber composition forming the reinforced rubber layer has a loss of tangent (tan δ) measured at 60° C. of 0.01 to 0.25, a JIS-A hardness measured at 23° C. of 70 to 95, and a breaking elongation in a tension test measured at 23° C. of 200% or more.
