Abstract 1. A method of bonding previously cured elastomeric tread material to a previously cured elastomeric tire body which is particularly adapted for solid tires permanently mounted on wheels, the method comprising the steps of buffing the tread face of the previously cured tire body, encircling the buffed tread face with a bonding layer of uncured rubber, encircling the uncured rubber with a previously cured tread material, interposing the tire body between a pair of sealing discs each having a circular sealing lip, sealingly engaging the side walls of the tire body with the lips of the discs, encircling the tire body and tread material with a flexible fluid impervious envelope which extends outside the sealing discs, sealingly engaging said lips of said discs with said envelope by exerting radially directed forces on portions of the envelope and pressing the envelope portions into engagement with said discs, and then adhering the tread material to the tire body by curing the interposed rubber while retaining the tread material and tire body in assembled relation with the envelope.
