Abstract
A pneumatic tire comprises a puncture prevention member adhered to at least a part of an inner surface of a tire body, wherein the puncture prevention member includes one or more protective layers each of which includes: an internal pressure retention layer; and a protective material located on a tire outer surface side of the internal pressure retention layer in at least a part of an extending region of the internal pressure retention layer.
Claims2
A pneumatic tire comprising
- a puncture prevention member adhered to at least a part of an inner surface of a tire body,
- wherein the puncture prevention member includes one or more protective layers each of which includes:
- an internal pressure retention layer;
- and a protective material located on a tire outer surface side of the internal pressure retention layer in at least a part of an extending region of the internal pressure retention layer;
- wherein the one or more protective layers each further include at least one selected from the group of a woven fabric and a knitted fabric on a region, the region is located in the tire outer surface side of the internal pressure retention layer and in a tire inner side of the protective material;
- and
- wherein the internal pressure retention layer is made of a material selected from natural rubber, synthetic rubbers, and thermoplastic elastomers;
- wherein the puncture prevention member includes a laminated plurality of protective layers as the one or more protective layers, and a plurality of protective materials circular in planar view are arranged in each of the plurality of protective layers, and
- the plurality of protective materials in each of the plurality of protective layers are arranged out of phase with the plurality of protective materials in each of other protective layers of the plurality of protective layers so that at least one protective material is present when the puncture prevention member is viewed in a lamination direction of the plurality of protective layers.
