Add the ability to change tire pressure before changing tires in a race.
Ideas
They will not add it, the tyre system works and the doesn't even bother to make it better, for example you should be able to use any tyre on practice and pirelli will took the most used but they just limit the tyres that you can use. the game is too arcade like to add those kind of details. people has been asking for year to improve some aspects of the game, like when crash no put that slowmo annoying cam cuz lack of simulation of physics.
