Patent number: 8960245Abstract: A pneumatic tire has a tread rubber formed by a nonconductive rubber and a side wall rubber formed by the nonconductive rubber. An outer surface of the side wall rubber is provided with a band-like diametrical conductive portion which is formed by a conductive rubber and extends along a tire diametrical direction. An outer end of the diametrical conductive portion is exposed to a ground-contacting surface or is connected to a conductive rubber member which is exposed to the ground-contacting surface. An inner end of the diametrical conductive portion is exposed to a rim contact region or is connected to a rim strip rubber formed by the conductive rubber. A narrow groove is formed by depressing an outer surface of the diametrical conductive portion and extends in a tire diametrical direction in a side wall portion.Type: GrantFiled: February 6, 2012Date of Patent: February 24, 2015Assignee: Toyo Tire & Rubber Co., Ltd.Inventor: Isao Yonetsu
