Title:
PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JP2016041521
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic tire which exhibits excellent electrification performance, low fuel consumption performance, steering stability, and crack growth resistance.SOLUTION: A pneumatic tire includes: a side wall part formed by laminating two or more layers of rubber including a side wall outer layer 1 for structuring a tire outer surface and a side wall inner conductive layer 2 which connects a clinch and a breaker and is arranged between a carcass and the side wall outer layer 1; a tread part; a bead part having the clinch; the carcass; the breaker; and a conductive rubber. The pneumatic tire has a specific structure, wherein a ratio of thicknesses of the side wall outer layer 1 and the side wall inner conductive layer 2, and a ratio of a storage elastic modulus E'1 of the side wall outer layer 1 at 70°C and a storage elastic modulus E'2 of the side wall inner conductive layer 2 at 70°C are respectively in specific ranges, and a volume resistivity value of the side wall inner conductive layer 2 is in a specific range.SELECTED DRAWING: Figure 1
