Patent ID: 8328973

Claim:
A method of manufacturing a radial fire for a construction vehicle, comprising: a band making step of making one layer of a carcass layer that arranges numerous steel cords in parallel into a cylindrical band, a wrapping step of wrapping a shape retaining layer consisting of a first shape retaining layer and a second shape retaining layer directly on an outer peripheral side of the carcass layer that constitutes the cylindrical band, such that the entirety of the first shape retaining layer is in direct contact with the carcass layer and the second shape retaining layer is laminated on an outer peripheral side in a central region of the first shape retaining layer, and inserting a pair of bead cores on the outer peripheral side of the carcass layer such that one of said bead cores is spaced, in a widthwise direction, axially outside of each widthwise end portion of the shape retaining layer, wherein said shape retaining layer includes numerous organic fiber cords arranged in parallel such that the organic fiber cords cross the steel cords of the carcass layer when making the cylindrical band, and wherein the organic fiber cords of the two shape retaining layers have a mutually intersecting relationship with each other, and a mutually intersecting relationship with the steel cords of the carcass layer.
