| 摘要 |
The present invention relates to a radial tire for an aircraft having a belt structure capable of sufficiently satisfying a demand for recent high pressure resistance without increase in tire weight and more particularly to a radial tire for an aircraft having a carcass serving as a framework and toroidally extending between a pair of bead portions, and a belt disposed on a radially outer side of the carcass and consisting of at least two belt layers consisting of plies having a plurality of organic fiber cords coated with rubber, wherein the belt is configured in such a manner that elongation at break Lout of a radially outermost belt layer is smaller than elongation at break Lin of a radially innermost belt layer, a ratio Lout/Lin satisfies the relationship 0.8<Lout/Lin<0.95, and elongation at break of a radially outer belt layer is not more than elongation at break of a radially inner belt layer between respective radially adjacent belt layers.
