It is an object to improve uneven wear resistance in a tread portion in a pneumatic tire having conductive rubber arranged in a part of the tread portion. Foamed rubber is provided in the tread portion 12 and a foamed rubber conductive layer 14 employing the foamed rubber is arranged in a part of the tread portion 12. Furthermore, uneven wear due to a difference of wear resistance between the foamed rubber conductive layer 14 and other tread rubber 22 can be suppressed by setting a foaming rate of the foamed rubber conductive layer 14 higher relative to other tread rubber portion 22. |
