The biggest source of drag on a car is air followed by tires.

Of course the makers are going to put hard tires on as well as
streamline the vehicle to get mileage up.

The less drag, the less gas the vehicle uses.

What's your point?


That is only true in cruise on the highway. In stop and go city driving
driveline friction is the majority, followed by inertia. Air and tire
is a small percentage combined.
