TIRE
Document Type and Number:
WIPO Patent Application WO/2019/117007
Kind Code:
A1
Abstract:
The present invention provides a tire including natural rubber as a rubber component, the tire being obtained by including, in at least one member selected from a side reinforcement rubber layer and a bead filler, a vulcanized rubber composition in which the difference {E'(A)-E (B)} between the dynamic tensile storage elastic modulus E'(A) at 180°C and the dynamic tensile storage elastic modulus E'(B) at 25°C is 2.0 MPa or more, the dynamic tensile storage elastic moduli being measured under the conditions of initial tensile strain of 5%, dynamic tensile strain of 1%, and a frequency of 52 Hz. The tire has an exceptional balance of ride comfort during normal travel and durability during run-flat travel.
