PURPOSE: A low noise tire restrains the generation of a sizzle noise and prevents the deterioration of a ride comfort. CONSTITUTION: A low noise tire is constituted by forming many protrusions(4) on the inner wall surface of a kerf(3). A blade forming the kerf(3) has many through holes for passing rubbers, thereby forming the protrusions(4) in the kerf(3). The protrusions(4) restrain the generation of a sizzle noise by reducing the compression and expansion volume of air. Thus, a noise generated in a process that an air compressed in the kerf(3) is exhausted is buffered and damped after being collided against the protrusions(4).
