PROBLEM TO BE SOLVED: To improve riding comfort by enhancing shock absorbing property and to prevent collapse and damage of articles to be transported, in a pneumatic tire provided with a side protector. SOLUTION: This tire is provided with a pair of bead cores 2, a carcass 3 for winding the bead cores 2 to form a toroidal shape, a belt layer 4 arranged at the tire radial direction outside of a crown part of the carcass 3, tread rubber 5 arranged at the tire radial direction outside of the belt layer 4, and side wall rubber 6 arranged at the tire outside of a side part of the carcass 3. The tire is provided with one or a plurality of projecting lines 8 connected continuously or intermittently in a tire peripheral direction in a first annular region R1 up to 30mm to 100mm in the vertical direction from a tire maximum outer diameter surface D on the surface of the side wall rubber 6, and a plurality of ribs 9 connected continuously in the tire peripheral direction in a second annular region R2 from a position of 30mm in the vertical direction from the tire maximum outer diameter surface D up to a grounding end P. By this structure, deflection of the tire is promoted by the ribs 9 to absorb shock from a road surface and to improve riding comfort. COPYRIGHT: (C)2005,JPO&NCIPI
