On our Track the Soft Tyre can run only two laps fast, than the brake is more bad then with use hard tyre, they work for ten laps.
If we change the settings on soft tyre the different is less and you can run always the soft tyre.
But for real race i do not find a good setting, so that different tyres make different strategy and all can be good for a real race.
Like:
Take hard tyre, save fuel and do one pit stop less
But the different was alltime to big or to less , so that only one Tyretyp make sense.
Maybe you have a good setting. let me know
Please do not misunderstand, the program is great, this is a suggestion for improvement
