<p>PURPOSE: A pneumatic tire is provided to efficiently improve drainage performance and snow performance. CONSTITUTION: An air tire (1) includes a center main groove (3A), a pair of shoulder main grooves (3B), and a pair of center main grooves (4A) in a tread unit (2). A groove width (W1a) of the center main groove is formed more largely than a groove width (W1b) of the shoulder main groove. An angle (α7) on the tire circumference direction of a shoulder transverse groove is formed more largely than an angle (α4) on the tire circumference direction of an outer center transverse groove. The outer end connected to the shoulder main groove of the outer center transverse groove and the inner end connected to the shoulder main groove of the shoulder transverse groove face each other by including the shoulder main groove.</p> |
