I was wondering me why the most powerful cars have usually tyres with a great band widht. Surely it is not a question of adherence, because friction factor is not a function of the contact area, but the type of surfices. Does it do with traction stability?. I have heard that F1 cars have reduced their tyre widht bands when running also in dry floor, in order to limit the speed. If they reduce the contact area then the traction force would be the same because friction factor is not modified. Thus, what is the true reason?
