Abstract
A projecting pedestal is provided on a surface of a sidewall portion of a pneumatic tire. The projecting pedestal projects along the surface and includes a projecting front-end surface formed of a flat surface. A two-dimensional code is provided on the flat surface of the projecting pedestal. A normal line direction of the flat surface is inclined toward a rotation axis of the pneumatic tire at an angle ranging from 10 degrees to 45 degrees with respect to a tire lateral direction of the pneumatic tire, in the pneumatic tire not mounted on a rim nor inflated with air.

A pneumatic tire, comprising:
- a projecting pedestal provided on a surface of a sidewall portion of the pneumatic tire, the projecting pedestal projecting along the surface and including a projecting front-end surface formed of a flat surface, the surface of the sidewall portion being a curved surface;
- and
- a two-dimensional code provided on the flat surface of the projecting pedestal, the two-dimensional code formed of a dot pattern including two types of gray scale elements identifiably formed by surface irregularities, and
- a normal line direction of the flat surface being inclined toward a rotation axis of the pneumatic tire at an angle ranging from 10 degrees to 45 degrees with respect to a tire lateral direction of the pneumatic tire, in the pneumatic tire not mounted on a rim nor inflated with air;
- wherein
- the dot pattern includes conical dot holes, the conical dot holes having a diameter of from 0.1 mm to 1.0 mm and a hole depth of from 0.3 mm to 1.0 mm and surfaces of the conical dot holes being defined by laser-burned rubber, and
- a ratio of a maximum projection height to a minimum projection height of the projecting pedestal is from 105% or more to 120% or less.
