Abstract
A bias tire for an aircraft includes a laminate formed by laminating a plurality of plies intersecting with each other and reinforced by organic fiber cords having a large thermal contraction coefficient. Both ends of the plies are turned up around bead cores. A profile curve I of a representative ply corresponding to that number counted from an innermost ply of the laminate plus one, which is one half of a total number of the plies when the tire mounted on a normal rim is filled with 1% of a normal inner pressure is constructed by a smoothly changing crown profile curve J and a smoothly changing side profile curves K. The crown profile curve J intersects a natural equilibrium profile curve H and is positioned between natural equilibrium profile curves E and H between both shoulder ends. The side profile curves K contact both the natural equilibrium profile curves E and H at rim points and smoothly connecting with the crown profile curve J and are positioned outwardly of the natural equilibrium profile curves E and H between the shoulder ends and rim points.
