ABSTRACT:
An apparatus for reducing extra large vehicle tires to particles or to prepare them for recapping comprises a tire holder assembly, made up of a set of dual jacks, in combination with a rotary cutter blade assembly made up of a side-by-side series of discs carrying cutter blades of chisel type. The set of dual jacks are preferably carried by an arbor having opposite shaft ends adapted to matingly interconnect with corresponding ends of a motivating shaft for quick and easy interchange of one size tire holder assembly for another size. When the tire is to be recapped, arcuate attachments are secured to members of the tire holder assembly that contact a tire bead so as to preserve the circumferential integrity of such bead during cutting, and the cutter blade assembly is replaced by wire buffing brushes following removal of the tread portion of the tire by cutting. An optional feature of the invention is the freezing of the tire prior to cutting, so that steel reinforcing materials as well as the elastomeric material of the tire can be easily reduced to particles.
