My favorite tires depends on what I'm doing.
Normals when I'm doing drift aracade races agaianst the AI.
Sims when I'm in free run mode trying to smoke up the tracks for show.
Slicks when I'm using a high powered (400+ HP) car
Softs when I'm grip racing.
My preferences are grippier tires (non-sims), because I have more fun working to get a good drift.
I doubt all the great drifters rely on sims (Its just that we see many of the good drift clips to be from sims), if you have good fient motion, like with help from a wheel, you don't need sims and can produce the same drifts with normal tires. It's more rewarding. But for exhibition and for show, sims makes things easier. "If someone is offended by this, don't be, I enjoy using sims too, you know its true and sims makes your drifting life easier becauase you don't have to rely on your weight transfer like you do with gripper tires, you can just gas it hard and turn in to produce more angle".
