The invention provides a tread pattern which is required to have traction with respect to the ground and which suppresses generation of vibration during traveling of a vehicle, and provides a tread pattern which provides traction and reduced vibration regardless of expected usage conditions or under usage conditions that are different from expected usage conditions. Means for Solution A tread pattern which provides improved traction with reduced vibration generation in which a contact patch is divided in the width direction thereof into right and left areas with respect to the traveling direction of the vehicle and each of the right and left areas is provided with tread lugs, wherein long-, middle-, and short-pitches are provided in each of the right and left areas, the tread patterns of the right and left areas are asymmetrical to each other, and total areas of the contact patches of each of the right and left areas are substantially equal to each other. 1, 1 1 , 1 2 , 1 3 : tread lugs; L 1 : long pitch; L 2 : middle pitch; L 3 : short pitch
