    Dear Francisco

    You must get 2,1 bars when the tyre is warm. To reach this preasure when the tyre is cold, you can begin with 1,5 bars. Run for 3 laps, and when the tyres are warm, stop and chek the tyre pressure to get 2,1 bars.

    hi everybody, the tech info of the car say 1,3 in cold and 1,6 in warm.............I think is too low, but the car runs better with this pressure.

    probe pyrometer will tell you the correct pressure which is driver/tire/track condition specific.
