We've seen a lot of pics of the 18" wheels with the aero wheel covers on, and off. But, I don't think we've yet seen a video or step-by-step photos or even a description on how the covers are installed or removed. Looking at the wheel cover, it appears that the center Tesla-logoed disc is removable, perhaps by popping it out like the Model S wheel, or by unscrewing it. It also appears that the five slots around the Tesla disc are integrated into the black plastic part of the wheel cover (as opposed to the gray parts). Perhaps a special tool must be inserted into this slots to remove the cover, after removing the Tesla center disc. The cover can't be removed by rotating; it must be pulled straight off because of the tire valve. Thoughts? Speculation? Blatant conjecture?
