| 1. A tubeless tire wherein an air chamber is formed between an inner face of a tire body and a rim thereof, by mounting said
tire body to the periphery of said rim; and
an inner liner layer is formed on said inner face of said tire body,
wherein said inner liner layer comprises a rubber composition containing as rubber components,
60 to 100% by weight of at least one kind of butyl rubber selected from the group consisting of butyl rubber, halogenated
butyl rubber and a halogenated copolymer of isomonoolefin having 4 to 7 carbon atoms and paraalkylstyrene; and
0 to 40% by weight of at least one kind of diene rubber selected from the group consisting of natural rubber, isoprene rubber,
styrene-butadiene rubber, butadiene rubber and styrene-isoprene-butadiene rubber; and
silica as an inorganic filler, wherein the content of said inorganic filler is at least 10 parts by weight based on 100 parts
by weight of said rubber component; and
a gas barrier layer is formed on an inner face of said inner liner layer, wherein said gas barrier layer is formed of a gas
barrier resin composition which contains an inorganic layered compound having a particle size of at most 5 μm and an aspect
ratio of 50 to 5000, and a resin,
wherein said resin is polyvinyl alcohol.
