<p>Apparatus for reducing to particles tread portions and beaded side wall portions of vehicle tires (19), particularly extra large vehicle tires (19), or for preparing such vehicle tires (19) for recapping, comprises a tire holder assembly (10), having a paired set of dual jacks (163 carried by opposite ends, respectively, or elongate, rigid. tire clamping frames (14). and a rotary, cutter blade assembly (13) made up of chisel type offset from one another to provide a helically oriented series of such cutting blades (13). An optional but important feature of the invention is the progressive cutting of the tire (19) in a cryogenic atmosphere which freezes exposed surfaces of the tire, and the mounting of a group of separate, residual, beaded side wall portions (19-1) of sequentially cut tires (19) in the tire holder assembly (13) of the same apertures for cutting such side wall portions (19-1) down to the heavily reinforced beads (51) thereof.</p> |
