PROBLEM TO BE SOLVED: To provide a core support-type pneumatic tire that can improve durability of a pneumatic tire during core traveling and durability of a core, even when the nominal width of the pneumatic tire is great.SOLUTION: A core support-type pneumatic tire includes: a pneumatic tire 3; an annular core 4 for supporting the pneumatic tire 3 from the inside when internal pressure is decreased; and a rubber core holding member 5 that is arranged between the core 4 and an outer peripheral surface of a rim 1 to which the pneumatic tire 3 is fitted. The plurality of cores 4 spaced from one another along a tire width direction are arranged on the rubber core holding member 5. Each of the cores 4 has the inside ring part 41, the outside ring part 42, and a web part 43 for connecting the inside and outside ring parts 41 and 42 to each other.SELECTED DRAWING: Figure 1
