Title:
TIRE
Document Type and Number:
WIPO Patent Application WO/2020/080150
Kind Code:
A1
Abstract:
Provided is a tire provided with a clinch apex composed of a rubber composition for a clinch apex, wherein the rubber composition has a complex modulus of elasticity E*
(E*(70°C)) of 6-13.0 MPa at 70°C and in a strain of 1%, a loss tangent tanδ (tanδ(70°C)) of 0.10 or less at 70°C and in a strain of 1%, and tanδ (tanδ(100°C)) of 0.07 or less at 100°C and in a strain of 0.5%, and satisfies formula (1): tanδ (70°C)/E*
(70°C)×1000≤10.0. According to the present invention, it is possible to provide a tire having improved low heat generation and high-speed durability while maintaining clinch apex capabilities such as steering stability and ride comfort.
