Abstract
An airplane tire, whose rated pressure is more than 9 bar and whose deflection under rated load is more than 30%, comprising a tread having a tread surface (41), a crown reinforcement (42) comprising at least one layer of reinforcing elements, and a carcass reinforcement (43) comprising at least one layer of reinforcing elements; said tread surface (41), crown reinforcement (42) and carcass reinforcement (43) being defined geometrically by respective initial meridian profiles. The initial meridian profile of the crown reinforcement (42) is locally concave across a central part whose axial width l42 is at least 0.25 times the axial width L42 of the crown reinforcement.
