Abstract:
A pneumatic tire includes a plurality of protrusions on a bottom of each of the grooves. The height of the protrusion is variable in a profile of the protrusion in a circumference direction of the pneumatic. The protrusion has at least one peak portion that protrudes away from a center of the pneumatic tire. The pneumatic tire further includes a connection member between the protrusion and an adjacent one of the lands, the connection member having a first end toward the land and a second end toward the peak portion, a height of the first end from the bottom of the groove being larger than that of the second end.
