The top of the wheel wells are exposed to allow a pressure release from under the car. This means the tire is spinning backwards into open airflow, if you tried to create a high pressure down force area here, drag would be insane as its in contact with the top of the tire spinning + moving 220MPH, so a 440MPH difference to airflow. You want to keep high pressure air from flowing into these zones, so air is instead directed around the sides to provide high pressure air in channels above under tunnels to produce the downforce.
