Abstract
A pneumatic tire for a two-wheeled vehicle having high lateral stiffness and exhibiting improved steering stability has a tread pattern defined in a tread portion by numerous sets of combination lug groove patterns. In this tread portion, one set of the left and right sides of the lug groove patterns is reverse W-shaped as a whole in the tire rolling direction, each of mid bending points P on both sides of the reverse W-shape is arranged at the region of 20-80% of a tire tread half width TW from a tire central circumferential line EC, an angle of the lug groove component to a tire shoulder portion from the mid bending point P is 20-70° with respect to a tire equatorial plane E, and an angle of the lug groove component to the tire central circumferential line EC from the bending point P is 20-70° with respect to the tire equatorial plane E.
