Eli5: Why are f1 tires smooth and grippy, but street tires with no tread are dangerous and slippery

Question

When you Google why are f1 tires smooth, the answer is no tread means more surface area, so better grip, but when you Google why do street tires have grooves, the same answer comes up. I’m confused. Also, is this a physics question, engineering or technology? Lol

Answer 1

Downforce

F1 cars have so much downforce with their aerodynamics, the surface area of the tire gives more grip/control of the car.

Using treaded tires in the rain is to give the water a path to escape.
