Radial tire for car

Abstract

Abstract PURPOSE:To prevent a radio receiver and such from generating noise by specifying the carbon black content of the rubber of a side wall section, particle diameter, and the electric resistivity between a bead section and the center of a tread section within a preset range. CONSTITUTION:A tire 1 is designated so that the electric resistivity R between the bead section 2 of the tire 1 and the center C of a tread section can be set to 200MOMEGA or more. For this purpose, a side wall section 6 sets the carbon black content to 5wt% or more and less than 25wt% for the whole rubber weight and uses the rubber containing the carbon black whose average particle diameter is 20mu or more and less than 60mu. As a result of this structure, a radio receiver and such can be prevented from generating noise without deteriorating the tire strength.
