Abstract: Extended-mobility tire includes at least one carcass-type reinforcement structure, with each of the tire's sidewalls being reinforced by a sidewall insert. Each bead of the tire includes an anchoring zone permitting the reinforcement structure to be held on a rim and including an anchoring rubber mix with a series of circumferential cord windings. Each bead further includes a bead seat zone formed of a rubber mix of modulus ME10 which is less than that of the mix of the anchoring zone and arranged radially internally of the anchoring zone. The bead seat zone physically separates the anchoring zone from the seat of the rim when the tire is mounted. The bead seat zone has a maximum thickness of 2.8 mm, and is preferably equal to or less than 2.2. mm. This arrangement makes it possible to increase the tire's lateral rigidity, without adversely affecting the intrinsic properties of the tire's rim zone and/or the sidewalls.

Abstract: A method of estimating the temperature of the air in the internal cavity of a tire in which: prior to normal operation, a series of running tests are carried out on the tire provided with a means of measuring the internal air temperature at given speeds V and external temperatures Tamb, the tire supporting a given load and the cavity being at a given internal relative pressure, and an adjustment is made to a function giving the temperature of the internal air Tai according to the parameters of speed and external temperature; and in normal operation, the tire equipping a vehicle under the above conditions of load and relative pressure, the internal air temperature is estimated according to the speed of the vehicle and the temperature external to the vehicle. The method ia applied to the detection of abnormal operating in particular of a running-flat system.

Abstract: The invention concerns a method for assessing the range of a motor vehicle run-flat system comprising at least for each wheel a tire casing, a deflation alarm and means supporting the running tread of the tire casing when the casing is deflated, which method, from the instant the deflation alarm has detected a predetermined deflating threshold, includes the steps of: periodically measuring the distance covered and a parameter C(t) characteristic of the running conditions; determining on the basis of C(t) and the measured distance over &Dgr;t a quantity characteristic of potential elementary damage of the system during the elapsed time &Dgr;t; calculating an estimate of the global damage by combining the calculated elementary damage levels since the start of flat running; and transmitting to the vehicle driver a quantity related to that estimate of the flat running system global damage.
