How retreading is made


Noktop retreading process

Tyre retreading is comparable to manufacturing a new tyre, and the whole process is strictly controlled by legislation and authorities.

Initial inspection

Only flawless tyre carcasses are approved for Noktop retreading.

Rasping

The old tread pattern of the tyre carcass is rasped away completely, leaving a roughened surface. A new inspection reveals possible undetected damage.

FIlling the pits

Possible tiny pits revealed from the carcass are opened up and carefully filled.

Glueing

The tyre carcass is sprayed with adhesive optimized for Noktop retreading materials. This ensures the best initial grab. The special cushion gum sheet that comes between the tyre carcass and the new tread is installed.

 

Cutting the tread

The new tread is unrolled and cut accurately to a specific length.

Assembly

The protective plastic sheet is removed from the adhesive surface of the new tread. The tread is pressed firmly on top of the cushion gum.

Vulcanizing

The assembled tyre is placed in an envelope bag, and all the extra air is sucked off from the bag. The tyre is moved in to a vulcanizing chamber, where it is heated for a specific time in a carefully controlled pressure and temperature.

Ready for the road

After the final inspection and paint finish, the freshly retreaded tyre is ready for a new lease of life on the road.
