Retreading Procedure - Filling

Each individual skive is filled with raw rubber compound using extruder guns and is hand stitched in to remove any air voids. This is then trimmed smooth to the contour of the surface, ready for the build process.
   

Retreading Procedure - Building

Rubber compounds are one of the secrets to a successful retread.

Tytec hold a stock of various rubber compounds to enable a site specific retread to be built for individual customer requirements. The CNC computer, controlled by a red light laser system, allows the exact dimension of a tyre to be created. i.e: E3 or E
