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

Slick tires do grab the road better, but are terrible in rain as they have no grooves for the water to go.
