Abstract: A method of manufacturing a tire, a forming system for the tire, and the tire are provided. A preceding carcass cord from one feeding unit is used to form a carcass layer while being fed to a forming drum, and a leading edge portion of a next carcass cord is paid out from another feeding unit in advance. At a time when a predetermined length of the preceding carcass cord is fed, a splice mechanism is used to join the leading edge portion of the next carcass cord to the preceding carcass cord to make the leading edge portion of the next carcass cord continuous with the preceding carcass cord. Then, with the next carcass cord fed to the forming drum, formation of the carcass layer is continued to complete the carcass layer.

Abstract: In a tread pattern of a tire, a main groove side of a shoulder lug groove in a side of a first circumferential main groove inclines with respect to the width direction. In each of first intermediate lug grooves and inner lug grooves, a direction from one side toward the other side in the width direction is inclined to a side identical to a side to which the main groove side is inclined. The first intermediate lug grooves overlap with extension lines of each of the shoulder lug grooves extending from a closed end of each of the shoulder lug grooves along an inclination direction of the main groove side toward each of closed ends of the inner lug grooves. A second intermediate lug groove extends between two of the extension lines adjacent in the circumferential direction, in a direction along the extension lines.

Furthermore, the projection amount of the fins with respect to the plane tapers from the one circumferential edge portions toward other circumferential edge portions of the blocks.

Abstract: In a rubber temperature measuring device, a temperature sensor and a biasing member are disposed in an installation hole formed in a molding surface of a mold. The temperature sensor is biased by the biasing member and a temperature detecting unit at a tip end projects from the molding surface and is not in contact with the mold. The mold is closed and vulcanized in a state in which a green tire making contact with the temperature detecting unit presses the temperature sensor against biasing force of the biasing member and an opening portion of the installation hole is blocked by the temperature detecting unit. Temperature data detected by the temperature detecting unit is input to a control unit disposed outside the mold through a communication line extending in a communicating hole communicating with the installation hole.
