<p>PURPOSE: A pneumatic tire is provided to improve drainage performance while maintaining driving stability and noise performance. CONSTITUTION: A pneumatic tire comprises an outer shoulder main groove(3) in a tread part(2), an inner shoulder main groove(4), an outer crown main groove(5), an inner crown main groove(6), an outer shoulder horizontal groove(12), and an outer middle lug groove(16). The outer and inner shoulder main grooves and outer and inner crown main grooves are linearly formed along the circumference of a tire. The groove width(W3,W4) of the outer and inner crown main grooves are managed to be greater than the groove width(W1,W2) of the outer and inner shoulder main grooves in order to greatly ensure the rigidity of a shoulder inner side land part(11) and a shoulder outer side land part(7). The groove width of the outer shoulder main groove is formed to be smaller than the groove width of the inner shoulder main groove in order to improve the rigidity of the shoulder outer side land part. The outer shoulder horizontal groove is formed in the shoulder outer side land part. The outer middle lug groove is formed in a middle outer land part.
