PNEUMATIC TIRE FOR TWO-WHEELED VEHICLE

This invention provides a pneumatic tire for a two-wheeled vehicle with improved lateral grip at cornering, controlled tread wear in the shoulder regions, ensured uniformity of wear on the left and the right, and secured heat generation in the tread on an actual vehicle. The pneumatic tire has left and right dissimilar rubber layers (15b, 15c) disposed in an inner layer of the tread in the left and right shoulder regions (16), respectively. Of the left and right dissimilar rubber layers (15b, 15c), made of a dissimilar rubber of a smaller tan ´ than that of the rubber of a tread surface layer (15a), the width is within a range of 5% to 25% of the extended tread width, the position of the end on the tread edge (15z) side is within a range of 5% to 14% of the extended tread width as measured from the tread edge (15z), the position of the end on the center region (17) side is within a range of 15% to 30% of the extended tread width as measured from the tread edge (15z), and the thickness is 20% to 70% of the whole thickness of the tread. Also, the tan ´ of the rubber constituting the left dissimilar rubber layer (15b) disposed on the more frequently used left side is smaller than the tan ´ of the rubber constituting the right dissimilar rubber layer (15c) disposed on the less frequently used right side.
