HOT TYRE RETREADING
– consists of applying a crude rubber compound to the front and sides of the casing. The whole is then placed in a special vulcanising mould, where the final shape of the retreaded tyre is given.
The process takes about an hour, in a special hydraulic press heated to over 160°C – just like making new tyres.
The main advantages of this technology:
- thanks to the completely renewed sidewalls and tread pattern, you get a like-new tyre that can be regrooved over time
- full utilisation of the original casing capabilities, due to the fact that the process is carried out by the tyre manufacturers themselves
- a retread tyre is up to 40% cheaper than the equivalent new tyre
- increase in remaining tyre life by up to 100% again
- less waste to be disposed of
COLD TYRE RETREADING
– consists of placing a pre-vulcanised tread with its final tread pattern on the front of the casing. The tyre is then placed in a pressure chamber (autoclave) for approx. 3 hours, where the vulcanisation process takes place at a temperature of approx. 115°C.
The undoubted advantages of this technology are:
- lower service price
- faster recovery of retreaded casings
- a wider choice of tread patterns
The condition and age of the casing (which can be up to 10 years depending on the manufacturer) determines whether a tyre is suitable for retreading. Any lateral damage, as well as numerous punctures, abrasions and cuts to the casing that have corroded the steel plies, or unnatural bending of the casing caused by running at low pressure, will disqualify the tyre.
If the casing is in good condition, then any tyre can theoretically be cold retreaded.
Hot retreading tends to apply to premium brands: Michelin, Goodyear, Dunlop, Continental and Bridgestone, but there are also exceptions like: BFGoodrich included in the medium brands.
It is worth noting that even if a tyre passes the initial ‘visual’ selection, it may be rejected in the later stages of verification at the factory, where the casing is found not to meet the quality requirements after the removal of tread residue or x-ray (mainly for hot retreading).
We are a valued brand on the domestic and international market. Our knowledge and experience puts us among the leaders in tyre retreading in Poland.
