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

Thr rubber is softer than your standard tires, so when it heats up it gets almost tacky.
The smoothness gives more surface contact area when in dry conditions, which is good, but in wet conditions, they change them out for tires with tread that will minimize the risk of the tire simply floating on top of the water at speed, which while reducing contact area, increases the ability of the tire to maintain contact with the ground itself, because you can’t steer well(if at all) on water at high speeds in a car.
