PROBLEM TO BE SOLVED: To provide a run flat tire with high temperature reduction effect of a tire side part capable of suppressing failure in baring. SOLUTION: Such that an angle formed by outer end parts 21 in a tire radial direction r of a plurality of turbulence flow generation protrusions 20 formed on a surface of the tire side part 3 and the surface of the tire side part 2 becomes 40°or less, height toward an end edge is gradually reduced. An upper surface 21A and the surface of the tire side part 3 are continuously formed such that they become the same plane. COPYRIGHT: (C)2009,JPO&INPIT
