Correct track pressure

The correct pressure helps warm up the tyre, essential for achieving optimum performance.

Correct track pressure

 

There are several key parameters for determining the correct tyre pressure for track use such as:

  • The choice of tyre: the MICHELIN track range offers a wide choice depending on use and level of riding skill. Amateur riders will get better performance from a MICHELIN Power Slick Evo that they’ll be able to warm up very quickly rather than from a MICHELIN Power Slick Ultimate that they’ll find difficult to get to and/or keep at the right temperature.
    - MICHELIN Power Slick Ultimate and MICHELIN Power Cup Ultimate, for professional competitors and riders only
    - MICHELIN Power Slick Evo, the versatile slick track tyre
    - MICHELIN Power Cup Evo, the versatile treaded track tyre approved for road use and FIM Supersport and Superbike compliant
    - MICHELIN Power RS, the sport road tyre for occasional track use
  • What the tyre is used for: Racing or Track Day
  • The air temperature
  • Whether tyre warmers are used or not

For competing riders equipped with the Michelin Ultimate range, the Michelin technical teams can provide on-the-spot advice on adjusting tyre pressure depending on:

  • track temperature
  • track abrasiveness

 

Pressure recommendations

 

These pressure recommendations are made taking track use into consideration. For road use, it is the manufacturer's pressure recommendation which applies. For racing tyres approved for road use or road tyres for occasional track use, it is essential to ensure that you reset pressure to road use after completing your laps on the track.

 

Use of tyre warmers:

It is important to check that the tyre warmers are working properly before visiting the track.
Make sure you have a service stand so that the wheel does not touch the ground and wrap the warmer around the tyre avoiding too much puckering. This will ensure better heat distribution.
Plan to leave the warmer on for 1 hour at a temperature of 90°C and protected from the sun and wind.

 

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.
