1. A method of detection of a run-flat condition of a vehicle tire, said tire being mounted on a wheel, wherein:
- a quantity f(α
, t) is sensed, which varies with the angular displacement of the wheel in time;
measuring signals are developed from that quantity, which vary with the angular speed of the wheel dα
(t)/dt;
a quantity characteristic of the dispersion of measuring signals is calculated;
an alarm is set off when the characteristic quantity satisfies a given ratio.

Abstract
A method of detection of a run-flat condition of a vehicle tire, said tire being mounted on a wheel, wherein:
- a quantity f(α, t) is sensed, which varies which the angular displacement of the wheel in time;
- measuring signals are elaborated, which vary with the angular speed of the wheel dα(t)/dt;
- a quantity characteristic of the dispersion of measuring signals is calculated;
- an alarm is set off when the characteristic quantity satisfies a given ratio.
