Title:
PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JP2012192876
Kind Code:
A
Abstract:

To provide a pneumatic tire capable of preventing an adverse influence to current-carrying performance due to rim friction while reducing volume of conductive rubber in rim strip rubber.

The pneumatic tire, including: a carcass 4 that extends from a tread part 3 to a bead part 1 via a sidewall part 2; tread rubber 13 formed of non-conductive rubber; sidewall rubber 12 formed of non-conductive rubber; and rim strip rubber 11, has a conductive sheet 6 that is formed of conductive rubber, and reaches the rim strip rubber 11 from the tread rubber 13 while passing between the carcass 4 and the sidewall rubber 12, and terminates without being exposed on the outer surface of the bead part 1. The rim strip rubber 11 is divided into a non-conductive rubber part 11a and a conductive rubber part 11b. The conductive rubber part 11b is connected to the conductive sheet 6 and also exposed on the bead bottom surface.
