Precise positioning and securement of annular envelope-sealing members in desired relationship with a rim-mounted tire, having a replacement tread strip and a flexible impervious envelope thereon, are achieved by mating screw-threaded members carried by and extending axially of the tire-mounting rim and each of the annular members. The screw-threaded means carried by the tire-mounting rim may be and preferably is fixedly connected thereto when the rim is of a two-part type used for curing purposes, and may be releasably connected to a tire-mounting rim of a unitary cylindrical type such as is employed for the vehicular mounting of a truck tire.
