<p>PURPOSE: A tire for a two-wheeled vehicle is provided to reduce energy loss caused by the deformation of tread rubber because a crown groove reduces the amount of rubber on the equator of the tire and lowers the land ratio of the center. CONSTITUTION: A tire for a two-wheeled vehicle comprises a crown groove(11) which is extended around the equator(C) of the tire in a tread part(2) at an angle equal to or less than 20 degrees with respect to the circumference of the tire. The crown groove is arranged in a center area(Cr) that is 30% of tread width(TW), and the land ratio in the center area is 75%~95%.</p> |
