The tire () for a passenger vehicle has an axially central portion and axially lateral portions. The axially central portion and each axially lateral portion satisfies just one of conditions I, II, III: I—the portion comprises no transverse cut ('), II—the portion comprises N transverse cuts (′) arranged in such a way that π×OD/N≥40 mm, III—the portion comprises N transverse cuts (′) arranged in such a way that π×OD/N≤24 mm, condition I or II being satisfied by the axially central portion or by an axially lateral portion, and condition III being satisfied by the axially central portion or by an axially lateral portion.

A weft fabric (T) for tires () comprises several textile warp reinforcing elements () and several weft reinforcing elements (), wherein the moisture regain MR of the weft reinforcing elements () is less than or equal to 2.0%, the moisture regain being determined according to standard ASTM D 885/D 885MA of January 2010 the weft reinforcing elements () interweave the warp reinforcing elements (), and the weft reinforcing elements () are hairy.

A method for processing inflation defects of a tyre of a vehicle is disclosed, the tyre being equipped with sensors for measuring the pressure and the temperature of the internal cavity of said tyre. The pressure and the temperature of the internal cavity of the tyre are measured periodically and, as soon as an inflation defect of a tyre is detected, an alert is signalled to the driver of the vehicle, in which there is also transmitted to the driver of the vehicle a maximum speed setpoint: which, when the measured inflation pressure of the tyre is greater than or equal to a first inflation pressure threshold value p, is a first maximum speed setpoint value V; and which, when the measured inflation pressure of the tyre is less than said first pressure threshold value pand greater than or equal to a second pressure threshold value p, decreases as a function of said measured inflation pressure of the tyre.
