<p>A pneumatic tire capable of co-existing both a steering stability on a dry road surface and a water-discharge property on a wet road surface at a high level while suppressing conicity by appropriating the effective ground-contact area of a tread part and the shape of the cross section of a tread ground-contact surface in the lateral direction of the tire. In the tire (1), a plurality of peripheral grooves (7a), (7b), and (7c) extending along a tire equatorial plane (E) are formed in the tread part (6), and asymmetrical tread patterns are formed in both tread half areas (8) and (9). When the tire (1) is installed on a vehicle, the effective ground-contact area (Sout) of the tread half area (8) positioned on the outside of the vehicle is larger than the effective ground-contact area (Sin) of the tread half area (9) positioned on the inside of the vehicle, and a tire radial distance (Hout) from a tread ground-contact edge (10) positioned on the outside of the vehicle to a tread part tread position (11) crossing the tire equatorial plane (E) is smaller than a tire radial distance (Hin) from a tread ground-contact edge (12) positioned on the inside of the vehicle to a tread part tread position (11) crossing the tire equatorial plane.</p> |
