I am curious of the benefit these would provide,Off hand without really understanding their use i am thinking that a spat ahead of the tire would be of benefit by reducing the amount of air that will pass over the rolling tire, thereby reducing the air resistance on the rotating tire.
The rear of the tire spats seem like they would restrict the air from leaving the rotating tire, causing unneeded drag.
