A tire having (i) an asymmetric tread profile with a shoulder drop difference of 0.3 to 0.9; and (ii) an asymmetric tread pattern so as to have a ratio between the inner void/solid ratio and the outer void/solid ratio of 1.1 to 1.50. By the above combination of features, handling and aquaplaning performance is remarkably improved even at high operating speeds without negatively affecting the wear resistance of the tread band.
