Abstract: A low-noise tire (1) for a heavy-duty vehicle, having a tread (2) having at least two juxtaposed complex circumferential cuts (41, 42) which are separated from one another by a circumferential row of raised elements (5). Each complex circumferential cut (41, 42) has an alternation of external cavities (61, 62), which are distributed at a circumferential pitch (Pc), and of internal cavities (71, 72). Pairs of raised elements (5) are separated by sipes (8), having two ends (I1, I2), and distributed at a circumferential pitch (Pi). The circumferential distance (Di) between the respective two ends (I1, I2) of any sipe (8) is equal to the circumferential pitch (Pi) of the sipes (8), and the circumferential pitch (Pc) of the external cavities (61, 62) is equal to the circumferential pitch (Pi) of the sipes (8).

Abstract: An aircraft tire comprises a tread (2), having an axial width L, which comprises a middle portion (3) having an axial width LC at 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 (41, 42), positioned axially on either side of the middle portion (3), each having an axial width (LS1, LS2) 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.

Abstract: A method determines an inflation pressure expected in an aircraft tire provided with a pressure and temperature sensor. Also disclosed is a method for assistance in the maintenance for an aircraft tire and also a portable electronic device intended for assistance in the maintenance.
