METHOD OF AND MOLD FOR RETREADING PNEUMATIC TIRES ABSTRACT OF THE DISCLOSURE: A resilient mold and a method for retreading tires using such mold which has an inner face of a normal, unstretched diameter which is smaller than the outer diameter of a tire tread. The mold is in the shape of a ring and has, on its inner side or face, an embossing pattern which applies a tread design to a vulcanizable rubber band previously applied to a tire body. The ring mold is first expanded and then fitted over the tire body and the so- applied vulcanizable band and, thereafter, the ring mold is allowed to contract responsive to its inherent tension. The ring mold, thus fitted over the tread band, is centered on the body while the tire is rotated. This whole unit is then heated to a temperature which converts the tread band into a plastic form and embosses the tread design from the ring mold onto the tread band, which is vulcanized and bonded to the tire body. The air between the mold and the band may be evacuated and the mold may be subjected to ex- ternal pressure to assist in embossing the mold pattern in the tread band. The mold inner face is shaped so as to con- fine the tread band between such face and the tire body.
