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

Tread tires don’t generate more grip on a perfectly dry, flat surface. Slicks do. Tracks are inspected, cleaned or swept, and race on clear dry days usually. Tires for the general public and road conditions have treads to deal with rain, snow, debris and such.
