The tire model and the track surface model are both quite basic in GT5 and they go hand in hand. How different compounds work in real life depends on the track conditions, but in GT5 there seems to be no track condition variation except for the wet surface (and i'm not sure how accurate that is). My opinion is that the tire choise is just another method of tweaking the difficulty level in GT5.
