The object is to provide a pneumatic tire designed to promote.

  Another object of the present invention is to provide a pneumatic tire capable of easily grasping tire characteristics by making it possible to distinguish the unique structure or unique material employed in the tire from the outside of the tire. It is in.

In order to achieve the above object, the pneumatic tire of the present invention is a pneumatic tire provided with an inner liner layer having an air permeation preventing function on the tire inner surface, wherein the inner liner layer includes a thermoplastic resin. The display portion is formed on the outer surface of the sidewall portion, and information on the material of the inner liner layer is displayed on the display portion.

Further, the thickness of the inner liner layer is preferably 0.001 mm to 0.5 mm, and more preferably 0.01 mm to 0.3 mm. Such a thin inner liner layer having a high air permeation preventing function requires caution when repairing punctures or filling tire pressure, and it is therefore significant to display the information. The air permeability coefficient is a value measured under a temperature condition of 30 ° C. in accordance with JIS K7126 “Plastic Film and Sheet Gas Permeability Test Method”.

  The inner liner layer is preferably composed of a thermoplastic resin composition containing a thermoplastic resin.

And good.

  The thermoplastic resin composition preferably contains an elastomer in addition to the thermoplastic resin. Thermoplastic resins generally have a higher elastic modulus than rubber constituting tires, and are susceptible to cracking or peeling due to poor adhesion, but these disadvantages can be obtained by blending an elastomer into the thermoplastic resin composition. Can be supplemented. In this case, the elastomer may be at least one selected from the group consisting of a diene rubber and its hydrogenated product, an olefin rubber, a halogen-containing rubber, a silicon rubber, a fluoro rubber, and a block copolymer.

It is a meridian half section view showing a pneumatic tire according to an embodiment of the present invention. 1 is a side view showing a pneumatic tire according to an embodiment of the present invention.

  Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2 show a pneumatic tire according to an embodiment of the present invention.

  As shown in FIG. 1, the pneumatic tire of the present embodiment includes a tread portion 1, a pair of sidewall portions 2 disposed on both sides of the tread portion 1, and the tire portion radially inward of the sidewall portions 2. A pair of arranged bead portions 3 is provided. A carcass layer 4 is mounted between the pair of bead portions 3 and 3. The carcass layer 4 is wound up around the bead core 5 disposed in each bead portion 3 from the tire inner side to the outer side. A bead filler 6 made of a rubber composition is disposed on the outer periphery of the bead core.

  On the other hand, a plurality of belt layers 7 are embedded on the outer peripheral side of the carcass layer 4 in the tread portion 1. These belt layers 7 include a plurality of reinforcing cords inclined with respect to the tire circumferential direction, and are arranged so that the reinforcing cords cross each other between the layers. In the belt layer 7, the inclination angle of the reinforcing cord with respect to the tire circumferential direction is set in a range of, for example, 10 ° to 40 °. Further, a belt reinforcing layer 8 including a reinforcing cord oriented in the tire circumferential direction is provided on the outer peripheral side of the belt layer 7. In the belt reinforcing layer 8, the inclination angle of the reinforcing cord with respect to the tire circumferential direction is set to 5 ° or less, for example.

Further, an inner liner layer 9 having an air permeation preventing function is provided along the carcass layer 4 on the inner surface of the tire. The inner liner layer 9 is not composed of a general rubber composition mainly composed of butyl rubber, but is composed of a unique material having an air permeation preventing function superior to that of butyl rubber. The inner liner layer 9 can be composed of, for example, a thermoplastic resin composition containing a thermoplastic resin, but can also be composed of metal or ceramic deposited on the tire inner surface. . In any case, the air permeability coefficient of the inner liner layer 9 is 25 × 10 ⁻¹² cc · cm / cm ² · sec · cmHg or less, more preferably 10 × 10 ⁻¹² cc · cm / cm ² · sec · cmHg. It is good to be below. The inner liner layer 9 has a thickness of 0.001 mm to 0.5 mm, more preferably 0.01 mm to 0.3 mm.

  In the pneumatic tire provided with the inner liner layer 9 having an air permeation preventing function on the tire inner surface as described above, the display portion 10 for displaying information on the inner liner layer 9 is formed on the tire outer surface. . As shown in FIG. 1 and FIG. 2, the display unit 10 is disposed on the outer surface of the sidewall part 2, and a recess 11 that is recessed from the outer surface of the sidewall part 2 and a label 12 that is attached to the bottom surface of the recess 11. It consists of and. Information on the inner liner layer 9 is displayed on the label 12 using letters, numbers, symbols, patterns, and the like.

Is done. The display unit 10 may be provided on either one of the pair of sidewalls 2 or on both.

  In the pneumatic tire as described above, since the inner liner layer 9 carrying the air permeation prevention function is thinner than that made of general butyl rubber, the air permeation prevention function is impaired if excessively shaved during puncture repair. In some cases, the carcass layer 4 located below the inner liner layer 9 may be damaged. However, by displaying information on the inner liner layer 9 on the outer surface of the tire and making the characteristics of the inner liner layer 9 distinguishable from the outside of the tire, the tire characteristics can be easily grasped, and as a result, puncture repair can be performed. When performing, puncture repair can be appropriately performed according to the characteristics of the inner liner layer 9.

  In addition, even if the inner liner layer 9 is made of a material that does not easily cause air leakage, the characteristics of the inner liner layer 9 cannot be recognized from the outside of the tire when the pneumatic tire is assembled to the wheel. The user may set the air pressure higher to improve fuel efficiency. In such a case, braking performance may deteriorate if the air pressure is kept high. However, by displaying information on the inner liner layer 9 on the outer surface of the tire and making the characteristics of the inner liner layer 9 distinguishable from the outside of the tire, the tire characteristics can be easily grasped. Accordingly, the tire internal pressure can be set to an appropriate value. That is, in the pneumatic tire provided with the inner liner layer 9 having excellent air permeation prevention performance, it is not necessary to excessively increase the air pressure.

  In the embodiment shown in FIGS. 1 and 2, the case where the display unit 10 is configured by the recess 11 and the label 12 attached to the bottom surface of the recess 11 has been described. However, the structure of the display unit 10 is particularly limited. It is not something. For example, it is possible to attach the label 12 without providing the concave portion 11 in the sidewall portion 2, or to stamp information on the inner liner layer 9 on the sidewall portion 2.
