Abstract: A vehicle tire construction and method for retreaded (or new) tires involving the use of a single patch or more patches of cord of large mesh extending laterally of the tire casing between the buffed surface and tread rubber. The patch has stretchable or elastic cords, an intermediate portion thereof being connected to the cord ply layer of the casing and the ends projecting about half way or more of the sidewalls, and possibly as far as the beads, to vent air pockets which tend to accumulate. The patch makes use of the venting capabilities of the ply layers and, to some extent, the porous nature of the buffed surface.The patch may also be interposed between the outer surface of a pre-cured retread and the surrounding plastic envelope which protects the tread from steam pressure during the curing period of the cushion gum rubber interposed between the pre-cured tread rubber and the buffed surface of the tire to be retreaded. The patch will vent air pockets otherwise formed in the grooves of the tire tread and enable the plastic envelope to penetrate and conform to the grooves forming the tread and thus permit uniform application of steam pressure to all sections of the tread.
