Tyre Retreading Process
Initial inspection (Visual + NDT grading)
Check casing suitability: look for cuts, sidewall bulges, inner-liner separation, exposed cords, zipper damage, previous bad repairs and remaining undertread. Many plants also perform electrical inspection/shearography/X-ray to detect internal separations before any work starts.
Buffing
Remove the worn tread and true up the crown to a uniform profile and specified undertread thickness. Buffing produces the prepared surface (correct radius and texture) needed for good adhesion of the new tread. Use the proper hub, pressure and PPE — buffing speed/profile matter a lot for a reliable retread.
Casing repairs / patching
Repair any penetrations, fractures, separated belts or cuts using approved repair methods (patches, plugs, splice repairs). Repairs must be completed and tested before building.
Cementing / adhesive application
Depending on system: apply primer/adhesive (cement) to the buffed area where required (precure systems typically use a bonding cement + cushion gum). This readies the casing for tread bonding. (In some modern systems cement is minimized by using extruded cushion gum).
Cushion gum application / filler
Apply cushion gum (also called bonding gum or bonding strip) where needed to fill skives and create a compliant layer between the cured casing and the new tread. This layer equalizes geometry and helps the tread bond and flex with the casing.
Tread building / tread application
Place the new tread (pre-cured tread for precure process, or prepare uncured tread for mold-cure systems) and assemble the splice. For precure systems the precured tread is cemented and spliced to form a continuous band.
Mounting / envelope fitting (enveloping)
Mount the assembled tire on the curing rim/drum and fit the curing envelope (diaphragm/inner envelope and outer envelope as needed) to obtain uniform heat & pressure during curing. Proper envelope fitting and rim selection are critical for an even cure.
Tube (if applicable)
If the tyre is a tube-type tyre, fit the heavy-duty curing tube (or use an inner envelope system where appropriate). Many modern retread workflows for tubeless casings use inner envelopes instead — tube fitting is conditional on tyre type.
Mounting on curing rim / flange
Secure the tire/envelope assembly to the curing rim or into the curing chamber as required by your system (pre-cure vs mold-cure setups may use different fixtures).
Curing / vulcanization
Expose the assembled tire to the required time, temperature and pressure in the curing chamber (autoclave or press). This step vulcanizes the bonding layer and integrates tread and repairs with the casing to form a single, durable structure. Proper cure cycle control is essential to avoid undercure, overcure, or separations.
Deflation / cool down, finishing & final inspection
Remove the tire from the oven, cool, trim the tread splice and finish the bead/shoulder areas. Do a final visual and functional inspection (high-pressure air test, uniformity checks, verify repair quality, bead/liner integrity) and reject any tire that fails. Return to service only when it meets acceptance criteria.
