  • Patent number: 4263074
    Abstract: An improved annular shaped tire liner which is adapted to fit inside of, around and in contact with a casing of a pneumatic tire and in compression by the casing and a method for preparing the tire liner is described. The liner has a thickness which provides substantial protection against penetration of the tire to the inside of the casing. The tire liner is characterized by having a section which is an annular strip of high pressure and temperature vulcanized and molded rubber, preferably of the type used for bonding to the outside of a tire casing as a tread, with ends joined by a thin section of low temperature and pressure vulcanized rubber. The low temperature and pressure vulcanized rubber is preferably derived from a vulcanizable rubber used to bond the molded rubber to a tire casing and is sometimes referred to as "cushion rubber".
