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

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?

The part you missed is race cars have to pull off the road and swap their slicks for treads when it rains even a tiny bit.

Being unable to drive at all during the rain is why normal cars use treads all the time and why the roads are textured instead of smooth. In the dry, smooth concrete with slick tires are the grippiest combo you can get. In the wet, it’s the worst. So to prevent people from having to change their tires at the first hint of rain, we use a decent combo for every condition. You know there’d be people going “it’ll be right, don’t need to change the tires yet” then crashing
