Abstract
(EN)
A pneumatic tire having a conductive rubber arranged in a part of a tread portion wherein uneven wear resistance is improved in the tread portion. A foamed rubber is arranged 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). Uneven wear due to difference of wear resistances between the foamed rubber conductive layer (14) and other tread rubber (22) can be suppressed by setting the foaming rate of the foamed rubber conductive layer (14) higher relative to other tread rubber portion (22).

L’invention concerne un pneu possédant un caoutchouc conducteur dans une partie de la bande de roulement, la résistance à l'usure hétérogène étant améliorée dans la bande de roulement. Un caoutchouc alvéolaire est agencé dans la bande de roulement (12) et une couche conductrice de caoutchouc alvéolaire (14) qui emploie le caoutchouc alvéolaire est agencée dans une partie de la bande de roulement (12). L’usure hétérogène due à des différences de résistance à l’usure entre la couche conductrice de caoutchouc alvéolaire (14) et l’autre caoutchouc de roulement (22) peut être supprimée en établissant une proportion alvéolaire de la couche conductrice de caoutchouc alvéolaire (14) supérieure à celle de l'autre bande de roulement en caoutchouc (22).
