Cars don’t weigh enough to make sufficient traction with CoF. And slick tires are better in the dry because of reduced deflection and better mechanical resilience allowing you to use a more aggressive compound without worrying about mechanical failure of compound, not because area means anything to the friction equation.
Also protip: CoF of a given rubber compound changes with temp, sticky summer racing tires are hockey pucks in the cold.
