Technically, the amount of rubber touching the road is just a function of the weight on the wheel and the tire pressure. With wider tires the shape is wider making the ratio of the wheel touching/not touching the ground smaller. This means better cooling on high speeds, nothing more.
You could lower the air pressure to make the touch area bigger, but that reduces the pressure on the ground and changes nothing either (if the friction would be linear, which I don't know if true in this case).
I agree with your first point, wider tires look better.
