Perhaps someone should take high school physics. More bumps do not equal more grip. If this were so, drag racers, NASCAR racers, IRL racers, Formula 1 racers, etc., would want bumpy race surfaces. The very opposite is true. They put smooth grippy tires on smooth track surfaces. The reason street tires are not smooth like race tires, is that they have to be able to displace water.
