In a tire for a levitation-type vehicle for supporting a load which varies depending upon a change in speed of the levitation-type vehicle at landing and during subsequent traveling thereof, a configuration of a crown and rigidity of the crown are set so as to have a ground-contact configuration in which, when a load of the levitation-type vehicle is equal to or less than 45% at its full load, a ratio of a ground-contact length of a pair of shoulders in a circumferential direction of the tire with respect to a ground-contact length, in the circumferential direction of the tire, of a central portion of the crown in the widthwise direction is 0.6 SIMILAR 1.5. Accordingly, the tire for the levitation-type vehicle has a wide ground-contact area at an initial stage of landing and traveling. |
