Abstract
A pneumatic tire includes a tread portion including a contact patch which occurs when the tire is mounted on a standard wheel rim with a standard pressure and loaded with a certain tire load at zero camber angle. The contact patch, on a respective tire load, defines a ratio Lc/Ls of a crown contact circumferential length Lc at an axial center of the contact patch to a shoulder contact circumferential length Ls at an axial location of 80% of an axial maximum width of the contact patch. The ratio Lc/Ls upon being loaded with 40%, of a standard tire load is equal to or less than 125% of the ratio Lc/Ls upon being loaded with 70% of the standard tire load.
