Document Type and Number:
Japanese Patent JP2023160726
Kind Code:
A
Abstract:
To provide a tire for a two-wheeled vehicle that is improved in detachment resistance performance of a boundary surface between a center part and a shoulder part of a tread part.SOLUTION: A tire for a two-wheeled vehicle includes a tread part 2 including a center part 8A and a pair of shoulder parts 8B including tread ground contact ends 2e, where 70°Ctanδ(c) and 70°Ctanδ(s) satisfy formula (1) of 1.30<70°Ctanδ(s)/70°Ctanδ(c) and 0°CE*(c) and 0°CE*(s) satisfy formula (2) of 0°CE*(s)/0°CE*(c)<1.50 when 70°Ctanδ(c) represents a loss tangent at 70°C of a rubber composition constituting the center part, 0°CE*(c) represents a complex elastic modulus at 0°C thereof, 70°Ctanδ(s) represents a loss tangent at 70°C of a rubber composition constituting the shoulder part, and 0°CE*(s) represents a complex elastic modulus at 0°C thereof.SELECTED DRAWING: Figure 1
