    Abstract: In a pneumatic tire, a belt layer includes an inner-side cross belt and an outer-side cross belt having an absolute value of belt angle with respect to a tire circumferential direction of not less than 46 degrees and not more than 80 degrees and having belt angles with signs that are opposite to each other; and a circumferential reinforcing layer having a belt angle with respect to the tire circumferential direction within the range of ±5 degrees and disposed between the inner-side cross belt and outer-side cross belt. Also, a distance Gcc on a tire equatorial plane from a tread profile to a tire inner circumferential surface and a distance Gsh from a tread edge to the tire inner circumferential surface satisfy a relationship 1.10≦Gsh/Gcc.

    Abstract: Tire for an aeroplane and, in particular, the crown thereof which comprises a tread (1), a working reinforcement (2), a carcass reinforcement (3) and a hoop reinforcement (4). The radially internal working layer (21) of the working reinforcement (2) comprises a concave portion. The hoop reinforcement (41) comprises at least one hooping layer (41) radially on the inside of the working layer (21) and made up of mutually parallel reinforcing elements, having a mean diameter D, that are inclined, with respect to the circumferential direction (XX′), at an angle of between +10° and −10°. The hooping layer (41) comprises at least one axial discontinuity (411) having an axial width (L411) at least equal to three times the mean diameter D of the reinforcing elements of the hooping layer (41).
