WIPO Patent Application WO/2012/005247
Kind Code:
A1
Abstract:
Disclosed is a pneumatic tire for two-wheeled vehicles that achieves functionality, safety, and economy, by reducing rolling resistance without reducing grip characteristics, i.e., without losing steering stability. The pneumatic tire for two-wheeled vehicles has a tread section (11) and, on both sides thereof, side wall sections (12) and bead sections (13) that extend in that order. In at least an end section (E) within the contact region when going straight, the tread section (11) structure comprises a base rubber layer (11A) and a cap rubber layer (11B) layered in that order from the inside of the tire radial direction, and the base rubber layer (11A) tan δ at 60° is lower than the cap rubber layer (11B) tan δ at 60°.
