PROBLEM TO BE SOLVED: To provide a core support-type pneumatic tire that can improve durability of a pneumatic tire during core traveling.SOLUTION: A core support-type pneumatic tire includes a pneumatic tire 3, and an annular core 4 for supporting the pneumatic tire 3 from the inside when internal pressure is decreased. The core 4 has an inside ring part 41, an outside ring part 42, and a web part 43 for connecting the inside and outside ring parts 41 and 42 to each other. The width Ro of the outside ring part 42 satisfies the inequality, 0.40≤Ro/TW≤0.95, with respect to the width TW of a tread part 31 of the pneumatic tire 3.SELECTED DRAWING: Figure 1

    【課題】 中子走行時における空気入りタイヤの耐久性を改善することを可能にした中子支持式空気入りタイヤを提供する。【解決手段】 空気入りタイヤ3と、該空気入りタイヤ3を内圧低下時に内側から支持する円環状の中子4とを備えた中子支持式空気入りタイヤにおいて、中子4は、内側リング部41と、外側リング部42と、これら内側リング部41と外側リング部42とを互いに連結するウエブ部43とを有し、外側リング部42の幅Roが空気入りタイヤ3のトレッド部31の幅TWに対して0.40≦Ro/TW≦0.95の関係を満足する。【選択図】図1
