摘要
PURPOSE: A pneumatic tire is provided to improve thermal radiating ability of a side wall by installing a blade shaped structure and a cooling fin on a side wall wherein heat is generated.;CONSTITUTION: A pneumatic tire(100) comprises: a longitudinal part which is formed in at least a part of the sidewall; a transverse part; and a heat radiating protrusion(110) which includes a vortex groove(120) at the center surrounded with a pair of the transverse parts and a pair of the longitudinal parts. A slit is formed toward the width direction of the longitudinal part in a pair of the longitudinal parts. The bottom surface of the slit is inclined. The bottom surface of the slit of a pair of the longitudinal part is oppositely sloped about the vortex groove.;COPYRIGHT KIPO 2010
