In my case, when I check the tyre selection screen, it only shows 2 types of tyre (medium and hard), both mandatory, the problem started in Hanoi. I'm not sure if the problem persisted in China, since I choosed theses compound. In Netherlands it was raining (thanks god the game did not pushed me to use 2 dry compounds). I tryed to play as the game suggested and with a custom tyre selection. But it only worked when I made a strategy with a medium and a hard compound.
