A method of making a tire includes placing substantially circular sheets of polymeric material on top of each other until a tire is built to a predetermined width. A predetermined tread shape is formed along a circumference of the substantially circular sheets of polymeric material.

The aim of the disclosed solution is to present a method of inserting an insert to a tread a tire such that the insert, particularly a fragile insert such as an insert comprising electronic components, may be protected against gripping and impact forces during its insertion. The disclosed solution is premised on an insert being housed, at least partially, in a sleeve upon and during its installation to a tread of a tire. Thus, the sleeve may be employed to provide protection for the insert against gripping and/or impact forces during the insertion of the insert into the tread a tire.

Method for manufacturing a tyre (1) equipped with a communication module (20), consisting in successively, and in the order required by the architecture of said tyre, laying rubber products, notably profiled elements (50) and reinforcing elements on a given support in order to yield a green tyre (1), then in vulcanizing the green tyre to yield a tyre (1), wherein, prior to laying one of the rubber profiled elements (50) on the green tyre, a slot (52) is created starting from a surface of the rubber profiled element (50) and the communication module (20) is introduced into the slot (52).

A tire includes: a bead core; a bead filler extending to an outer side in the tire-radial direction of the bead core; a carcass ply which is folded back around the bead core; a pad member disposed on an outer side in the tire-width direction of the bead filler; and a first rubber sheet disposed in a state covering a folding end of the carcass ply which is folded back, between the bead filler and the pad member, in which a second rubber sheet covering an electronic component is disposed between the bead filler and the pad member on an outer side in the tire-radial direction of the first rubber sheet.

A flexible sensor unit is embedded in a tire. The flexible sensor unit includes a plurality of individual circuit boards. Each circuit board includes at least one electronic component. The at least one electronic component includes a radio frequency identification integrated circuit, a microcontroller unit, at least one sensor, a power source and a boost converter. Each one of a plurality of electrically conductive flexible connecting ribbons extends between the circuit boards. An end ribbon is electrically connected to at least one of the circuit boards. An antenna is disposed on the end ribbon. The antenna transmits data from the at least one sensor, as processed by the microcontroller unit, and identification data from the radio frequency identification integrated circuit, to an external reader.

A connecting member and method of forming the connecting member in an air maintenance tire is provided. The method includes providing a tire having a sidewall formed with an annular groove. The groove receives an annular air tube having a first end with a first fitting and a second end with a second fitting. A recess is formed in the tire sidewall along the annular groove at a location where the first end of the annular air tube is adjacent the second end of the annular air tube. A mold formed with a cavity is provided and the fittings are removably secured in the cavity. The mold is positioned on a surface of the tire sidewall and an elastomer or a polymer is introduced into the mold cavity. The mold is heated to form the connecting member on the tire sidewall.

A tire comprising a tread block made of tread material, a tread, of which a part is formed by the tread block, and an insert comprising a primary capacitive component and a primary inductive component. The insert extends in a longitudinal direction from a bottom of the insert to a top of the insert. The insert has a first cross section at a first longitudinal position and a second cross section at a second longitudinal position, wherein the first longitudinal position is located closer to the tread of the tire than the second longitudinal position, and the second cross section is greater than the first cross section. At least a part of the top of the insert does not form an interface with the tread material. A method for applying an insert into a tire. An insert is inserted into a blind hole of the tire such that the bottom of the insert is inserted deeper in the blind hole than the top of the insert.

Provided are a pneumatic tire and a method for manufacturing the same. At least one sensor unit including a sensor that acquires tire information is fixed to a tire inner surface via an adhesive layer, and an amount of silicon in a release agent detected by fluorescent X-ray analysis at least in a fixing region for the sensor unit is from 0.1 wt % to 10.0 wt %.

Described herein are systems and methods for determination of rolling resistance from a sensor or sensors in a tire or tires for application in smart cars to provide feedback to interested parties, such as Departments of Transportation or tire manufacturers.

Identification labels and their incorporation in rubber-based articles are described. The labels include RFID components and can be incorporated in tires. The labels can withstand the relatively harsh conditions associated with vulcanization.
