Abstract: An aircraft tire capable of suppressing rubber tire wear during landing and shocks which accelerate or decelerate an aircraft at touchdown includes, on a side of a tire body constituting an outer peripheral part of an aircraft wheel, a protrusion for receiving flight wind pressure. The wheel is rotated ahead of the touchdown by the action of the wind pressure received by the protrusion in a direction in which the wheel rotates during a landing roll. Weight is inserted into a hollow part of the protrusion. Through use of centrifugal force on the weight in association with a rotational motion of the wheel, the protrusion is deformed to change its wind pressure receiving area for bringing rotational speed of the wheel ahead of the touchdown close to a rotating speed of the wheel that is consistent with a flying speed of the aircraft making the touchdown.
