Anyone wanting good traction wants the proper compound. Too small of a contact patch and the (typically) softer tire wears too quickly to be useful. (tire wear as I understand is a function of abrasion which is affected by surface temp)

F = Cf *N (n in this case is the weight of the vehicle pushing down)

Note there is nothing there about surface area.
