Abstract
A pneumatic tire for motorcycle capable of increasing peel resistance of a joint portion between regions against a larger lateral force when a camber angle is large, characterized in that each approximate straight line at a meridional section of join lines between a central tread rubberand an intermediate tread rubberand between the intermediate tread rubberand a shoulder tread rubberis extended obliquely in a direction of intersecting a phantom extended line of the each approximate straight line with the tire equatorial plane inside the tire, and an intersecting angle β of the approximate straight line jof the join line between the intermediate tread rubberand the shoulder tread rubberwith a tangential line drawn to a joint point of these tread rubbers at a ground contact surface and located at the side of the tire equatorial plane is smaller than an intersecting angle α of the approximate straight line jof the join line between the central tread rubberand the intermediate tread rubberwith a tangential line drawn to a joint point of these tread rubbers at the ground contact surface and located at the side of the tire equatorial plane.
