ABSTRACT:
A tire retreading tube for use with a tire retreading rim formed from a pair of axially-adjacent rim sections, one of said sections having a cutout for the reception of the valve stem extending from the tube body and being formed with threads adjacent the tube. The tube has an extension of generally cylindrical form through which the stem extends, so that the extension surrounds the portion of the stem adjacent the tube, and functions as a spacer element and is effective to limit movement of the stem and the tube relatively to the rim section. Suitably, the spacer element threadedly engages the stem adjacent the tube, has a body which essentially fills the cutout circumferentially, and has end flanges to overlie the adjacent faces of the rim section with which it is to be associated.
