The paper describes the technology of remanufacture of massive tires for pulvimixers, based on the replacement of the traditional elastomer - rubber - with a more perfect polyurethane. The method consists of removing the worn rubber elastic rim and replacing it with an elastic polyurethane rim. The authors present a step-by-step technology for pouring, polymerization and removal of the solid tire from the injection mould for a two-component hot cured polyurethane of the Duotane trademark of CIL (UK) and Synair (USA). Specific recommendations are offered for reducing the wear of traction wheels and steering wheels.
