Disclosed herein is a tire having an electronic communication module including a radio device where the radio device is positioned between a first rubber layer and a second rubber layer, with the second rubber layer having a T50 cure time at 160° C. that is than the T50 cure time of the first rubber layer. Also disclosed are related methods for curing a tire with an electronic communication module including a radio device positioned between a first rubber layer and a second rubber layer, with the second rubber layer having a T50 cure time at 160° C. that is than the T50 cure time of the first rubber layer.

Tire with RFID enclosed in different rubber layers and related methods

A tire includes a pair of beads and a crown region including a circumferential tread disposed radially above a circumferential belt. The tire further includes a pair sidewalls extending from the pair of beads to the crown region. A body ply wraps around the pair of beads and terminates in a pair of turn up ends in the crown region, below the middle 30% of the circumferential belt. A conductive substance is disposed along a strip of the body ply.

Tire having a conductivity path

The present disclosure is directed to textile cords covered with a rubber composition of specified composition, tires having at least one component comprising the rubber-covered textile cords, and related methods for increasing aged cord coverage of rubber-covered textile cords and for preparing the rubber-covered textile cords. The rubber composition of specified composition includes silica filler in an amount of up to 20 phr and silane coupling agent in an amount of up to 5 phr.

Rubber-covered textile cords, tires containing same, and related methods

Disclosed herein are rubber compositions comprising a conjugated diene-containing polymer, a reinforcing filler including silica, a bi-functional silane coupling agent, and an unsaturated, non-sulfur silane coupling agent, where the ratio of the bi-functional silane coupling agent to the unsaturated, non-sulfur silane coupling agent is from about 5:1 to about 20:1. Also disclosed are related methods which include both in-situ reaction of the silica filler and the unsaturated, non-sulfur silane coupling agent and pre-reacting of at least a portion of the silica filler and at least a portion of the unsaturated, non-sulfur silane coupling agent.

Silica-containing rubber compositions containing specified coupling agents and related methods

A tire includes a body ply sheet having a rubber core defined by a top surface having a length and a width, a bottom surface having substantially the same length and width, and side surfaces having a common height. The rubber core is further defined by a top rubber layer and a bottom rubber layer. The body ply sheet includes reinforcement cords disposed between the top rubber layer and the bottom rubber layer. The reinforcement cords are spaced 0.1-4.0 mm apart from each other and span the width of the body ply sheet. Bleeder cords are disposed on the body ply sheet and spaced 8-12 cm apart from each other. Conductive cords are also disposed on the body ply and spaced 20-80 cm apart from each other.
