In Gpro you can only make a differenz between dry and wet-tyres. I would prefer it to mark the 4 different sort of dry-tyres with different coulours like in the real formula 1.
That way you would get better information of your opponents risks and what your curent place might be worth.
I've got nothing against this idea but it seems quite useless since we can usually figure out everyone else's tyres in the first 20-30 laps of the race.
