in the short races 25% and medium races of 35% the soft is used in the Sprint, as it is really better for a few laps. in the feature race in 25% races you use hard because you don't have stops and go with it until the end of the feature race. at 35% there is already a stop, and the tire used in the feature race is the one used in qualifying so far so good, there are some people who play at 35% that when playing the feature race the soft tire may be 100% worn out, this is a bug in the presentation lap, if it is activated your tire will show wear in the feature race. but the question here is about the long 50% and 100% complete races, as in these races the tire used in the Sprint is a hard one, in the Race feature the new hard tire does not appear, we have 3 hard ones available, one hard is used in training, another in the Sprint and the last hard tire in the race feature, but this last hard tire does not appear and the only hard tire that appears in the Race feature strategy is the already worn out hard tire that was used in the Sprint and the game forcing us to make two stops like you see in the photo above. for people who like bigger races this totally breaks the immersion in the game.
