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

729 views

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?

What nobody has said is that with race cars, they use slick tires to increase the amount of power they can use before the tire slips. A normal road car, when driven safely, should only ever experience wheel slipping in one situation, an emergency stop.

I have only once in my 15 years of driving (approx 200,000 miles) needed more grip and that was due to driver error when I was new but needed grooved tires probably every time I have driven.
