Abstract: An integrated tread wear sensor and tire pressure monitoring system sensor unit container for a tire includes a tread wear sensor plug and a sensor container. The tread wear sensor plug includes a cylindrical projection extending through an opening formed in a selected tread element of the tire. A flange extends outwardly from the projection and includes a contact surface that is mounted to an innerliner of the tire. A conductive wire is disposed in the tread wear sensor plug and includes proximal ends disposed in the flange and a distal end disposed near a radially outer surface of the projection. The sensor container includes a wall extending radially from the flange of the tread wear sensor plug and terminating in a lip. A container cavity is defined by the flange, the wall, and the lip, and receives a tire pressure monitoring system sensor.

Abstract: A tire sensor attachment structure is provided. The tire includes a pair of bead areas, a sidewall extending from each respective bead area to a tread, a carcass extending toroidally between each of the bead areas, and an innerliner that is disposed radially inwardly of the carcass. A sensor housing is attached to the innerliner, and defines an interior chamber. A sensor is disposed in the chamber. The tire sensor attachment structure includes a compressible body that is disposed in the chamber between the sensor and the innerliner.

Abstract: Novel functionalized rubbers having low hysteresis and good compatibility with fillers, such as carbon black and silica, have been synthesized. These functionalized rubbers, including functionalized polybutadiene rubber and functionalized styrene-butadiene rubber, can be beneficially used in making a wide variety of rubber products that have enhanced physical properties. These improved properties are realized because the functional groups therein improve compatibility with reinforcing fillers that are typically included in such rubber compounds. These functionalized rubbers are comprised of polymer chains of the structural formula: wherein Polydiene represents a polymer chain which is comprised of at least one diene monomer and wherein R1 and R2 can be the same or different and represent alkyl groups containing form 1 to 8 carbon atoms. These rubbers can also be functionally terminated with a silicon containing terminator.
