  • Patent number: 4971643
    Abstract: A method for retreading and partially replacing the belt of a pneumatic vehicle tire, possibly accompanied by the interposition of binder layers and the use of coatings. First the replacement belt ply or plies, and then the finish-vulcanized profiled tread strip, are placed upon the tire body. A pressure treatment, possibly at an elevated temperature, is then effected. In order, along with a relatively short vulcanizing or processing time in the vulcanizing apparatus, to be able to dispense with the use of steel bandages or sleeves, the replacement belt ply or plies are vulcanized prior to placing these plies on the tire body.
