PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in fashionability with changing color by environmental temperature or heat generated by travelling and also excellent in processability and color development. SOLUTION: The pneumatic tire comprises a rubber component, a non-carbon black-based filler and temperature-sensitive color-changing microcapsules encapsulated with a temperature-sensitive color-changing component reversibly changing color with temperature change, and has a temperature-sensitive color-changing rubber part 30 prepared by vulcanizing and molding a rubber composition obtained by directly dispersing the microcapsules in the rubber component. Preferably, the temperature-sensitive color-changing rubber part 30 forms at least a part of side wall area 14. COPYRIGHT: (C)2008,JPO&INPIT
