摘要： A run flat tire having a side reinforcing rubber part is disclosed. The side reinforcing rubber part is formed by a rubber composition having a ratio (M50H/M50N) of tensile stress (M50H) in 50% elongation at a measurement temperature of 100° C. to tensile stress (M50N) in 50% elongation at a measurement temperature of 23° C. of from 1.0 to 1.3. Ratio (tb10/tp10) of 10% vulcanization time (tb10) at a vulcanization temperature of 160° C. of a rubber composition for a bead filler to 10% vulcanization time (tp10) at a vulcanization temperature of 160° C. of a rubber composition for a covering rubber of a carcass ply is from 0.5 to 1.0.

摘要： A rubber composition comprises 100 parts by mass of a diene rubber component comprising at least one selected from the group consisting of styrene-butadiene rubber, polybutadiene rubber, natural rubber and polyisoprene rubber, the diene rubber component containing modified styrene-butadiene rubber modified with a functional group having an interaction with a silanol group on a surface of silica, from 20 to 120 parts by mass of silica, and from 3 to 30 parts by mass of hydrogenated non-modified nitrile rubber. A pneumatic tire has a rubber part comprising the rubber composition.
