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

They don’t. That’s why race cars use slick tires. They provide much more traction, but they’re awful at dispersing water and dirt and grime from the road. That’s what the grooves are for. They’re for helping you drive in rain, snow, ect.
