PURPOSE:To prevent a radio receiver and such from generating noise while a car is running by specifying the carbon black content of carcass rubber and the electric resistivity between a bead section and a tread center, respectively. CONSTITUTION:A toroidal carcass 3 between bead sections 2 and 2 is comprised with the rubber whose carbon black content is 10wt% of more and less than 25wt% and the electric resistivity R between the bead section 2 and the center C of a tread section 4 is set to 200MOMEGA or more. As a result of this structure, the deterioration of tire strength can be suppressed and the propagation of static electricity into a car body can be prevented and then a radio receiver and such can be prevented from generating noise. |
