    Have you tried setting a pit stop strategy in the setup menu before the race?

    I have never had a problem with tyre changes doing it this way. However, you do need to change the driver swap, but you should have enough time when coasting down the pit lane. This is in SP... it maybe different for MP sessions.

  2. Thanks all, I'll go practice pit stops

    Can't you set your pit stop strategy before the race starts?

    yes, but the issues is default is no tire change and full repair on everything when u start race.

    I always set my preference prior to lights going green on mdf screen... but really should be other way round...
    tire change, yes... repairs no.

    For new comers reading this... If you have any repairs checked whilst serving a stop and go penalty it will not clear.

  6. This was my issue
    This is the real issue with the sim, among other things

    Try setting the tyres in the Fuel and Strategy tab in the Setup menu before entering the race, not through the mdf before the lights go green. This way the tyre change should be ticked. Just make sure you set the pit stop count to one... sometimes it appears to default to 30.

    Not a lot you can do about the repairs, other than change them via the mdf.

    This usually works for me.
  8. I do prepare a pit strategy pre race however the checkbox is still off by default. In SP/offline I tried a practice pit stop, I set a pit strategy and saved it to my car set-up, entered pits and tyre box was checked, only had to manually change driver swap. So single player it works. Haven't try this in MP/online yet, maybe it works if the pit strategy is saved to the car set-up, can't test it out for a few days.

    Yeah, I usually make all of the setup changes needed and then save the settings before I enter an SP race. I don’t usually race MP/Online, so I cannot help here... hopefully it is the same.

    Bonjour je suis actuellement sur Spa et qui dit Spa dit pluie. Comme indiqué dans le premier message, les pneus sont illimités pour les courses de 24 heures. Mais comme je change et que je mets de nouveaux pneus pluie, la boîte est grisée, je n'ai pas le choix.

  11. When a SP race has more than one qualy, the AI uses the same tyres for all the qualys or a new set for every event? I know they have fuel for all sessions, but I don't know about the tyres... (limited sets)

    Sorry to summonate you, but Is there a way to refresh tyre set after race weekend is over?
    We restrict to 2 tyre sets in our sessions. Always that race (sunday) is over and we returns to practice session (friday or saturday) used tyre sets still worn.

    Only after disconnect and reconnect to server the tyre sets are refresh

    There is something i don't understand, for example: i'm running a full sprint race weekend wich consist in:
    - first practice 15 minutes (nº1 tyre set) left 4 new tyres set
    - second practice 15 minutes (nº1 tyre set again) left 4 new tyres set
    - First Qualy ( nº2 tyre set) left 3 new tyres set
    - Second Qualy (nº3 tyre set) left 2 new tyre set
    And now the question:
    - First race (nº4 tyre set) In middle race i have to change the tyres. I want to put nº 5 but in the MFD there is a circle next to tyre set number. For the tyres 1,2,3 and 4 it's an empty circle, but for the nº 5 it's a full white circle. What is the meaning of this? I thought the empty circle was new tires and the full circle used. It is not like this?
    - I have'nt start the second race but I supose that i will have to use nº4 and 5 tyre set again.
    Basically the question is the meaning and use of he circle in the MFD. Thanks!!

    Black circle means used tires, white means unused.

    Is there a way to "save" the MFD pressure settings after changing them in-race? Once I change tyre pressures, switch to another pit strategy and go back they reset back to settings as set pre-race.

    Unfortunately not and it would help a lot. Changing compounds or not knowing your start pressures as one quickly changed them prior to race start in variable conditions can cause some strategy issues as trying to work it all out whilst driving at tracks like Zolder which is not very easy. It's virtually impossible not to mess it up or cause a distraction.

    A couple of MFD threads however most of the suggestions never fruited..


    I have a few suggestions, here are the main ones:-


    Strategy < -/+ > : ("0" or "S" or "Start") (This would show the race start tyre pressures set in the tyre UI of the car setup in case you have not setup a strategy for that weather condition or the weather keeps moving around)

    Strategy < -/+ > : ("-1" or "L" or "Last") (This would show all tyre pressures set in the last pit stop)

    Logic: When changing the tyre compound from DRY to WET for a set strategy, do not reset the tyre pressures to a very low to the default wet weather settings. Because of this you loose the corner variance pressures that you have setup on your custom dry setup. Lets say I had 26.5 | 27.2 / 26.3 | 27.0 set for my dry strategy and then I change the compound to WET and now I get something like 23.5 | 23.6 / 23.2 | 23.4. I have now lost the difference of pressure variance between right and left and front and rear corners and these new pressures do not suit the current ambient temperature. This is a real pain when race conditions are on the border line of DRY and WET tyres.


    [ PSI to Strategy ] (A quick copy and past function/button that would copy all four tyre pressures from the tyre UI and paste them to the pitstop strategy UI.

    Agree with @Coanda 's comments. I admit I haven't delved into pitstops much (still researching/learning from various threads here), but I notice right away the things he mentions.
