how do tire treads actually generate more traction on flat surfaces?

Question

I can understand in off-roading because they would actually bite into the ground and push against it, but if the road does not deform into the treads then wouldn’t it be better to have them slick for more surface area? why do race cars use slick tires and not consumer vehicles?

Answer 1

Roads are full of debris, dirt, water, ec. You need a tire than can handle that, enter grooved tires.

Slicks do have better contact, but you need a dry, clean, flat road. Soon as you got some dirt, dust, some pebbles, slicks are significantly worse.
