Tire change on grid wet-dry

Hello there Chris,


I'd like to ask you if you used the advanced strategy settings? If YES, could you tell me what did you set, please?

More important in this case, what was your tyre selection for stint 1 in your main strategy? This is the only "dry" compound you are permitted to change to on the grid. So if you want the option to fit dry tyres on the grid you must select one of the dry compounds for stint 1.

I am guessing you set stint 1 in your main strategy to Inters which is why you had no dry tyre option.

It does work after a fashion but not in the way you want it to work. If you assume a dry race and set your main strategy accordingly but set the advanced strategy to Inters at 0mm then you should qualify on Inters but still have your first stint dry tyre available to you on the grid if it dries during qualifying. 

This is your choice as a manager, it's just one of those gambles you sometimes have to make where the outcome is in the lap of the weather gods. It is very rarely necessary to need to start on dry tyres if it was raining at lockdown but stopped soon after. Usually the track takes a while to dry so the Inters will normally still be a good starting tyre. So choosing a wet compound for your stint 1 main strategy if it is raining just before lock down won't normally cause you a problem.

This is precisely what I did yesterday morning in Canada, I selected Inters for stint 1 because it was raining. Unfortunately it stopped raining as the system locked for qualifying and by the time the race started the track was dry but the only compounds I had available on the grid were Inters and Wets so I was stuffed. It's quite a rare set of circumstances and unless the devs massively alter the coding behind advanced strategy we'll just have to learn to live with it.
