Tire with asymmetric conductivity path

Abstract

In one aspect, the invention is directed to a tire in which a first sidewall and a first chafer adjacent the first sidewall have an electrical volume resistivity lower than 108 ohm·cm. Moreover, at least one of a second sidewall and a second chafer adjacent the second sidewall has an electrical volume resistivity higher than 109 ohm·cm. In another aspect, each of a first sidewall and a first chafer comprises at least 39 phr of carbon black, and at least one of a second sidewall and a second chafer comprises at most 35 phr of carbon black. In still another aspect, a tire has first and second tread base layers, arranged axially beside each other, wherein the first tread base layer has an electrical volume resistivity lower than 108 ohm·cm, and the second tread base layer has an electrical volume resistivity higher than 109 ohm·cm.
