Claim:
A pneumatic tire comprising: an outer surface; an inner surface positioned radially inward of the outer surface; and, a puncture sealant laminate positioned radially between the inner surface and the outer surface, the puncture sealant laminate having first and second ends and comprising: a first layer of sealant material that extends from the first end to the second end of the puncture sealant laminate; a first layer of non-sealant material that is positioned radially outward of the first layer of sealant material and that extends from the first end to the second end of the puncture sealant laminate; a second layer of sealant material that is positioned radially outward of the first layer of non-sealant material and that extends from the first end to the second end of the puncture sealant laminate; a second layer of non-sealant material that is positioned radially outward of the second layer of sealant material and that extends from the first end to the second end of the puncture sealant laminate; a third layer of sealant material that is positioned radially outward of the second layer of non-sealant material and that extends from the first end to the second end of the puncture sealant laminate; wherein the first and second layers of non-sealant material prevent the first, second, and third layers of sealant material from contacting each other; wherein each of the first and second layers of non-sealant material have first and second ends that attach to rubber in the pneumatic tire that is not part of the puncture sealant laminate; and wherein the first, second and third layers of sealant material consist essentially of the same material.
