Cracks in the rubber caused by the cold

In competition and hypersport tyres, the very high temperatures encountered (related to the very high levels of grip) require a specific blend of tyre compounds to withstand them.

One consequence of this is that these soft compound tyres have a break point around 0°C.  Handling these tyres at this temperature or lower may result in the tread or other area of rupper on the tyre literally breaking. 

Care must be taken to store the tyres in appropriate conditions which avoid these temperatures.. If this occurs, the tyres should not be handled at all.

Our recommendations
  • Never handle the tyre in temperatures below 5°C in order to avoid any damage or deformation.
  • Make sure the tyre has been stored at a temperature above 10°C for at least 24 hours before fitting and unfitting.
  • If you notice any cracks in the rubber, the tyre should not be used.

 

Reaching the correct temperature

The tyre needs time to reach optimum performance level, enough for the internal temperature to rise from 50°C to more than 80°C.

Every time you take your bike out, ride the first few miles at a modest speed to allow the tyre to reach the ideal temperature for the best grip.
