I pulled mine today (with 510 miles on my car). Two observations, all my wheels have “nicks/marks” in them from where the Aero Covers snap on to the wheel spokes, and the amount of brake dust on the wheels was significant, far more than I would have expected given I configured my braking mode to Standard/Hold even before we drove it off the lot. It seems given that finding owners who NEVER remove the Aero Covers could have a real mess on their hands.
