A pressure measuring device for a tyre includes an electronic circuit distributed over a first face and a second face of an electronic board and comprising a pressure sensor mounted on the first face of said electronic board; an antenna connected to the electronic circuit; a first housing part covering the first face such that together they delimit a first volume, and comprising channels fluidically connecting the first volume to the outside; a second housing part covering the second face such that together they delimit a second volume, and having a base for resting against an inner surface of a tread of the tyre, the second housing part being arranged such that the antenna projects laterally with respect to said second housing part and the housing has a centre of gravity located in the second volume spaced apart from the electronic board.

A rim for a braked aircraft wheel includes an outer circular portion whose ends are terminated flanges for receiving a tire. The outer circular portion is connected by a wheel disk to a hub for fitting on an undercarriage axle in order to rotate about an axis of rotation coinciding with a central axis of the rim. The rim is designed to receive the tire on the outside of the outer circular portion and a brake on the inside of the outer circular portion, the outer circular portion presenting on one side of the wheel disk that is to receive the brake, in a plane containing the central axis of the wheel, a profile that has two slopes forming non-zero angles with the central axis, the two slopes extending in the continuation of one another from the wheel disk to the corresponding flange and flaring towards said corresponding flange.

An aircraft tire comprises a tread (), having an axial width L, which comprises a middle portion () having an axial width Lat least equal to 50% and at most equal to 80% of the axial width L of the tread and consisting of a middle rubber composition, and two lateral portions (), positioned axially on either side of the middle portion (), each having an axial width (L, L) at least equal to 10% and at most equal to 25% of the axial width L of the tread and each consisting of a lateral rubber composition. The middle rubber composition comprises in particular from 25 to 85 phr of a tin-functionalized butadiene and styrene copolymer and from 15 to 75 phr of isoprene elastomer, and at least one lateral rubber composition is different from the middle rubber composition.
