Beschreibung
Zusammenfassung:	An outside support rubber for a run-flat tire, a run-flat tire and a test method are provided in the present application. A modulus loss rate of the outside support rubber satisfies: \|1-G'2/G'1\|≤6%, wherein G'1 is a modulus obtained before a zero-pressure driving simulation of the run-flat tire, G'2 is a modulus obtained after the zero-pressure driving simulation of the run-flat tire, and G'1 and G'2 are both measured under condition that a temperature is 55-60°C, a frequency is 600cpm, and a strain is 7%. When the outside support rubber is used in a run-flat tire, a sufficient supporting performance, a tensile fatigue resistance and an excellent low heat generation performance can be ensured, so that the run-flat tire can be reused after being repaired instead of replacement, and sustainability and low carbon are achieved
