Embodiment Construction

[0084] first exemplary embodiment

[0085] Next, a first exemplary embodiment of a tire according to the present invention will be described with reference to the drawings.

[0086] like Figure 1A and Figure 1B As shown, the tire 10 of the present exemplary embodiment has a cross-sectional shape similar to a conventional pneumatic tire made of conventional rubber for vehicles.

[0087] The tire 10 is provided with a tire case (tire frame member) 17 including a pair of bead portions 12 , a sidewall portion 14 , and a crown portion 16 . Contact, the sidewall portion 14 extends from the bead portion 12 to the radially outer side of the tire, and the crown portion 16 connects the radially outer end of the sidewall portion 14 on one side with the radially outer end of the sidewall portion 14 on the other side. The outboard ends are connected together.

[0088] The tire casing 17 of the present exemplary embodiment is formed of a first thermoplastic material.

[0089] The t...

Abstract

To easily manufacture a tire the color of which does not fade due to traveling, a tire case (17) which is a tire (10) structural member is formed by injection molding using a colored first thermoplastic material which contains a pigment. A tire the color of which does not fade due to traveling can be easily manufactured.

Description

technical field [0001] The present invention relates to a tire fitted to a rim and a tire manufacturing method. In particular, the invention relates to tires formed at least in part from thermoplastic material and to a corresponding method of tire manufacture. Background technique [0002] Known pneumatic tires for vehicles such as passenger cars are composed of, for example, rubber, organic fiber materials, and steel members. [0003] However, used rubber is limited in terms of recycling, such as disposing of rubber by incineration with heat recovery or by shredding for use as pavement material. [0004] Recently, from the viewpoint of light weight and ease of recycling, it is required to use, for example, thermoplastic resins and thermoplastic elastomers as tire materials. [0005] For example, Patent Document 1 discloses a pneumatic tire molded from a thermoplastic polymer material. [0006] Tires made of thermoplastic polymer materials are easier and less expensive to...
