ABSTRACT:
The tire of this invention has a silica-rich tread compound for excellent rolling resistance and tread wear properties. The tire is made to be conductive such that electrostatic charges on the vehicle can be quickly dissipated when the vehicle stops. An electrostatic discharge ring is located on at least one shoulder portion of the tire and has a relatively low volume resistivity, on the order of 100 megohm centimeter. The discharge ring is positioned to make contact with a conductive sidewall portion of the tire. The overall resistivity of the tire from the rim to the ground surface is made to be less than about 100 megohms.
