<p><P>PROBLEM TO BE SOLVED: To provide a tire which suppresses generation of road noise due to the vibration of a buttress section and further decreases the road noise. <P>SOLUTION: A pneumatic tire 1 includes a tread 50, sidewalls 60, and buttress 70. In a cross section of the pneumatic tire 1 in the tread width direction TW, if the point at which a first curved line R1 which follows the curvature of the surface of the tread 50 and a second curved line R2 which follows the curvature of the surface of a buttress section 70 intersect is defined as an imaginary point IP and also if the point at which a straight line L passing through the imaginary point IP and substantially perpendicular to the carcass 20 intersects the surface of the pneumatic tire 1 is defined as an intersection point NP, the pneumatic tire 1 has a recessed shoulder region US including the intersection point NP and having a predetermined width. The recessed shoulder region US is provided with a plurality of recesses 80 recessed from the surface of the pneumatic tire 1 and with a surface section 90 in which no recess 80 is formed. The recessed shoulder region US extends along the tire circumference direction TC. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
