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.

Abstract: A rubber composition for an innerliner includes 100 phr of elastomers, including at least 60 phr of a butyl rubber, and 0 to 40 phr of diene-based rubber. The composition further includes 35 to 70 phr of a reinforcing filler and a curing system including zinc oxide and optionally a sulfur-based curing agent.

Abstract: The present invention is directed to a 3D-printed tire segment model having a tread portion comprising a plurality of grooves, ribs and/or tread blocks, and a plurality of blades extending out of the ribs and/or tread blocks, wherein the tire segment model is made of a 3D-printed polymer. Moreover, the present invention is drawn to a method of making a tire mold segment, including the step of 3D-printing the above tire segment model with a polymer.

Abstract: Aspects of the invention relate to a tire that includes a shoulder wedge arranged in a shoulder portion of the tire between the sidewall and the belt package, the shoulder wedge being at least partially inserted between the belt package and the carcass ply. The tread includes a tread chimney component extending from the shoulder wedge to the rolling surface. The overlay coat of the tire's belt package, the tread band except for the tread chimney component, the tread base and the tire sidewall are made from non-conductive rubber. A conductive path between the rolling surface and the rim is provided across the tread chimney component, the shoulder wedge, the carcass ply and the chafer portion.
