Aircraft tire

摘要

The present invention provides an aircraft tire having a carcass structure capable of sufficiently satisfying recent demands for high pressure resistance without increase in tire weight. An aircraft tire 9 includes a pair of bead portions 2 and a carcass 4 made by stacking two or more carcass layers 3 composed of cords coated with rubber, which toroidally extend between the bead portions 2. Further, with respect to carcass layers 3 of the carcass 4 which are adjacent to each other, elongation at break of a widthwise outer carcass layer 3 is smaller than elongation at break of a widthwise inner carcass layer 3.

1. An aircraft tire comprising:
a pair of bead portions; and a carcass made by stacking three or more carcass layers composed of cords coated with rubber, wherein the carcass serves as a framework, the carcass layers toroidally extend between the bead portions, and with respect to carcass layers of the carcass which are adjacent to each other, elongation at break of a widthwise outer carcass layer is smaller than elongation at break of a widthwise inner carcass layer, wherein spacing distance between each of adjacent carcass layers in the carcass increases toward a widthwise outer side from a widthwise inner side.
