III - Pressure track pressure / Use of tyre warmers

Contact Michelin Technical at 2wheelinfo@michelin.com for further advice. The pressure should be set at ambient temperature and depends on the tyres you have chosen to mount on your motorcycle:

For riders competing with the MICHELIN Power Performance range, Michelin s technical teams can provide expert advice on adjusting tyre pressure depending on:

Air/track temperature Track abrasiveness The rider s level of skill

Correct pressure enables optimum performance levels to be achieved (2).

(1) Pressure taken with tyre and rim at ambient temperature, just before the first ride or just before fitting the tyre warmers. (2) Michelin recommends setting the tyre warmer temperature to 194°F. (3) After riding on the track and before street riding, you will need to adjust the cold tyre pressure to the manufacturers recommended setting.

Use of tyre warmers

MICHELIN Power Slick², MICHELIN Power Cup² and MICHELIN Power Cup Evo are designed to have a short warm-up time: use of tyre warmers is not mandatory.

When using tyre warmers, the pressure set at ambient temperature before the first ride should be the same as without tyre warmers.

Using tyre warmers makes it possible to reach operating pressure more rapidly. In no cases does the use of tyre warmers make itpossible to start with a lower pressure. The main aim of using tyre warmers is to reach the optimum operating pressure faster to save on warm-up time at the beginning of the ride.

Tyre warmers should be used with a temperature of 90°C for at least 1 hour before the first ride.

In cold conditions, tyre warmers should not be set to too high a temperature. The colder it is, the lower the temperature of the tyre warmer should be in order to avoid the situation of tyres cooling down while riding. Tyres that cool down while riding can skew the rider s perception of actual performance levels.

Use of tyre warmers with the MICHELIN Power Rain is not mandatory. If it is used, they should be adjusted to temperature of 40°C.

These pressure recommendations are given for track use. For road use, the manufacturer s tyre pressure recommendation applies. With track tyres approved for the road, or road tyres for occasional track use, it is essential to ensure that tyre pressure is returned to the correct level for road use following use on the track.
