摘要： A pneumatic radial tire for an airplane comprises a pair of bead cores, a carcass comprised of at least one carcass ply, a main belt comprised of at least two belt layers, an auxiliary belt comprised of plural layers, and a tread, wherein the main belt has a lamination thickness satisfying 0.2 ≤ G 1 /G 0 ≤ 0.8 as a relation between a lamination thickness at the widthwise center of the tire (Go) and a lamination thickness at a position corresponding to 2/3 of a maximum width (G 1 ), and the tread satisfies 0.85 ≤ D S /D C ≤ 1.1 as a relation between a tread thickness at a widthwise center position of the tire (D C ) and a tread thickness at a position of a width corresponding to 80% of a maximum width of the main belt (D S ), and has a radius of curvature on an outer surface of the tread formed by filling a normal internal pressure satisfying 0.4 ≤ R 2 /R 1 ≤ 3.0 as a relation between a radius of curvature in a central region including the widthwise center of the tire (R 1 ) and a radius of curvature forming a widthwise side region outward from the central region (R 2 ) being connected to each other at a position corresponding to 40-60% of the maximum width of the main belt.
