<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of exhibiting excellent durability though white rubber is arranged at a sidewall part. <P>SOLUTION: The pneumatic tire includes a white letter part 12 which protrudes from white rubber 11 arranged outward in a tire radial direction than an outer edge of a bead filler 1b in the sidewall part 2 and a side reinforcing layer 20 which extends outward in the tire radial direction from a bead part 1. The outer peripheral edge 20a of the side reinforcing layer 20 is located outward in the tire radial direction relative to the inner circumferential end 12b of the white letter part 12, and when a length in the tire radial direction from an inner peripheral edge of a bead core 1a to the inner circumferential end 12b of the white letter part 12 is made to be H1, a length in the tire radial direction from the inner peripheral edge of the bead core 1a to the outer peripheral edge 20a of the side reinforcing layer 20 is made to be H2, and a length in the tire radial direction of the white letter part 12 is made to be T, (H2-H1)/T is set equal to or more than 0.3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
