To provide an aircraft radial tire in which a diameter of a tread surface is prevented from being increased during rotation, endurance against cutting due to a foreign object or the like is enhanced, and weight is reduced.SOLUTION: In a radial tire, a belt structure disposed radially between a carcass and a tread portion has a main belt layer, a first unreinforced rubber layer disposed on a radially outer side of the main belt layer, a second unreinforced rubber layer disposed within the main belt layer, and a protective belt layer disposed on a radially outer side of the first unreinforced rubber layer and a radially inner side of the tread portion. A radially outermost layer of the main belt layer has a plurality of reinforcement cords each having a diameter, and the first and second unreinforced rubber layers have first and second radial thicknesses, respectively, relative to the diameters.SELECTED DRAWING: Figure 1

    【課題】回転時にトレッド表面の大径化を防止し、異物等による切断に対する耐久性を高め、タイヤの重量を低減した航空機用ラジアルタイヤを提供する。【解決手段】ラジアルタイヤにおける、半径方向においてカーカスとトレッド部との間に配置されているベルト構造は、主ベルト層と、主ベルト層の半径方向外側に配置された第1の非補強ゴム層と、主ベルト層内に配置された第2の非補強ゴム層と、第1の非補強ゴム層の半径方向外側であってトレッド部の半径方向内側に配置された保護ベルト層と、を有する。主ベルト層の半径方向最外側の層は、それぞれが直径を有する複数の補強コードを有し、第1および第2の非補強ゴム層は、その直径に対して、第1および第2の半径方向厚さをそれぞれ有する。【選択図】図1
