Abstract
A pneumatic tire is provided with an asymmetric tread pattern which comprises an inboard shoulder longitudinal groove (A) at an axial distance Xi from the tire equator (C) and an outboard shoulder longitudinal groove (B) at an axial distance Xo from the tire equator (C). The distances Xi and Xo are 27 to 33% of the tread width (TW), and the axial distance Xi is less than the axial distance Xo. A tread crown region between the inboard edge (Ao) of the inboard shoulder longitudinal groove (A) and the outboard edge (Bo) of the outboard shoulder longitudinal groove (B) has a sea ratio of 30 to 50%.
