Tyre for a motor vehicle and method for controlling a motor vehicle during a manoeuvre to change direction and/or speed

A method for controlling a motor vehicle, the method comprising:

• equipping said motor vehicle with front and rear tyres respectively having a transverse curvature ratio of at least 0.2 and a total height to chord ratio of at least 0.5, both in normal driving conditions and on a racing track;
• wherein at least one of said tyres has an inflation pressure of between 50% and 90% of a low load reference value for normal driving, said at least one of said tyres having a tread and a radial carcass comprising textile cords that, at said inflation pressure, give the whole of the carcass a controlled elastic response that allows the motor vehicle to be controlled when there are sudden changes in speed and/or direction, said controlled elastic response resulting from a response of said textile cords that is substantially between about 140 N and about 200 N for an extension of about 3% and substantially between about 170 N and about 240 N for an extension of about 4%.
