Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same reference numerals are attached to the same parts, and description thereof will be omitted.

[0023] (1) Structure of pneumatic tire

[0024] refer to figure 1 The structure of the pneumatic tire 10 (hereinafter abbreviated as tire 10 as appropriate) of this embodiment will be described.

[0025] Such as figure 1 As shown, the tire 10 is assembled to a rim 60 for use. The inner space of the tire 10 assembled on the rim 60 is filled with gas such as air. In the present embodiment, the tire 10 is described as an aircraft tire mounted on an aircraft, but the tire 10 is not limited to an aircraft tire. The tire 10 can also be mounted on passenger cars, trucks (including off-road dump trucks), buses, and the like.

[0026] A balance patch 40 is attached to the back side of the tread 20 that is in contact with the road surface....

Abstract

This pneumatic tire comprises: at least one balance patch (40) that is positioned on a tire inner surface (30), which is a surface on an inner side of a tire (10); and a functional component (50) that has a communication function and is positioned on the tire inner surface (30), distanced from the balance patch (40) by a prescribed angle (theta) in the tire circumference direction.

Description

technical field [0001] The present invention relates to a pneumatic tire and a method for manufacturing the pneumatic tire. Background technique [0002] Conventionally, there is known an invention in which a balance patch is attached to the inner surface of a tire to adjust the weight balance of the tire (especially an aircraft tire) (Patent Document 1). The shape of the balance patch described in Patent Document 1 is a flat sheet, and it is attached to the inner surface of the tire using an adhesive. That is, the balance patch described in Patent Document 1 has the following problems because the entire surface of one side is stuck to the inner surface of the tire. [0003] When the tire is recycled, the tread rubber of the used tire is scraped off and a new tread rubber is attached. At this time, when there is a balance patch on the inner surface of the tire, the balance patch may be peeled off once, and then the balance patch may be pasted again to adjust the balance. ...
