Document Type and Number:
WIPO Patent Application WO/2012/005248
Kind Code:
A1
Abstract:
Disclosed is a pneumatic tire for a two-wheeled vehicle 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. A second tread rubber (11B), with a lower tan δ at 60° than a first tread rubber (11A) that forms a center region that includes the tire equatorial surface, is positioned in the tread section (11) at least in the vicinity of an end section (E) in the contact region when going straight.
