Very interesting observations.
FWIW, Are you running with grill block(s)? (Would affect volume of air
exiting the engine bay.)
SWAG^ on possible reasons:
* Less ice in the wheel wells -- perhaps the wheel caps diverts under-car
air, heated by passing through the engine bay, from passing through the
wheel, causing it to exit via the wheel well. Result: more warmish air
passing out at the back of the well and melting/reducing the ice?
* Less salt deposit on the side of the car -- smooth air flow aft of the wheel
well, vice turbulent flow, keeps salt from contacting the body?
Or does more concentrated flow noted above create an greater outward
velocity of air exiting the wheel well, blowing the salt spray outward?
