WARNING! Aero caps damage alloys!

So after 7 months and 7k miles I decided to take off my aero caps to clean and with a view to maybe leaving them off.
I was rather upset when I saw what they have done to my alloys.
The aero caps clip to the spokes of the wheels and the wheel centre and that part of the system seems to work pretty well the problems comes where they touch against the front of the wheel. The wheel has several pads built into it where the wheel is designed to touch the surface but it reality it touches in several other places as well including most of the way around the very edge of the rim. At all of these touch points and around the rim of the cap it has caused significant damage to the wheel surface.
The wheels themselves are undercoated in a very dark grey or black then painted anthracite and lacquered. They are clearly not powder coated which is part of the problem since that is much tougher.
Where the caps have rubbed on the wheel, in some places it is just the lacquer that is scuffed and can easily be touched up but in others the abrasion is all the way through to the undercoat.
It probably doesn't look quite as bad in reality as the attached photos make it look but its not good.
To try to stop further damage I have used a Dremel type tool to grind down the inside edge of the rim of the Aero cap ( which is very sharp BTW) and all of the touch points. Since the touch points are probably needed I have then built them up again with padded tape. I am hoping that this mod will prevent further damage. I mean I could go to Tesla about it but I am sure it would be considered "fleet standard or something"
Anyway I wanted to warn others. If you have Aeros and think you might take them off at any point you might want to do it sooner rather than later while your wheels are still in good condition. You could also try my mod but I can't say yet whether it will actually help at all or have any downside. I have done 1000 miles since the mod and no evidence so far that it has made things worse at least.

Hmmm, not good :(

I've just ordered some hub/centre caps in the view to take them off for a month or 2 over summer, if done just over 10k in mine so will have to go and investigate.

Mine have been off for some time now and yesterday a bag arrived to keep them in.
I am sure it has been covered but what is the range difference when not using them?

worst case is high speed i.e. motorway where you might be looking at 3-5% from what I have read. Will make no difference around town

Seems to show in their tables that the difference with the aeros actually narrows at higher speeds

I had seen that table in the past but hadn't looked in detail ... and that is indeed a surprising result. The benefit of the aero covers actually starts to reduce at the higher speeds... for SR+ 11 miles extra range at 60mph 9 miles at 70mph and 7 miles at 80mph compared with no aeros. Mind you every mile is valued in an SR+.

I'm only using mine on epic journeys (like 800 miles to the South of France). Bit of a design flaw though, wonder if there's any warranty comeback?

Mine came off a week after I got it. I did notice a small amount of scratching where they clip to the spokes but otherwise nothing.
I’ll make certain to inspect and tape the covers before and if they go back on.

I took mine off a few weeks ago but I can't recall noticing damage .. I'll look more carefully next time!

About 3 days before the original post of this I ordered my hub cap kit, (then I saw this thread!) didn't go for tesla ones (glad now i didnt) as thought might only be used for couple of months over summer, plus at the moment I'm doing alot less miles so thought i would try, anyway they came through the other day so thought i would wash car today and clean aeros remove and clean alloys below, and after 10k I've got same damage as OP.

Doesn't look as bad from standing height, but very annoying.

I'm also having one of my alloys repaired tuesday, and didn't really want to put aero caps straight on, wanted pai to harden.

But looks like I'll be putting aeros back on sooner than I thought due to the damage

@Jason71 did you try contacting tesla to see if they would do anything?

I’m surprised to see so many people removing them. I don’t think they look that bad, maybe it’s just me but every time I see one with the bare alloys they look a little meh but maybe that’s because I’m not in love with the alloy design.

No. I haven't. This is Tesla we are talking about. I have no illusions that they will accept any responsibility. I know I probably should ask but it's clearly not specific to my car it's a design issue so they will be opening a can of hurt for themselves if they do. Kinda suprised it's not come up before though. Surely I'm not the first to notice??

I must admit, I took an aero cap off to have a look, based on this post, and also because I wanted to look at the alloy, to see whether I really liked it.

And, meh. I think I'll just leave them on. The standard alloys aren't all that great to me. The look of the aeros has grown on me since I've had the car.

In terms of why this isn't a common discussion point, I guess a lot of people either remove the caps at delivery, or just leave them on permanently, so probably have damaged wheels and aren't aware. How many people regularly take them off to look?

If there any any straightforward ways to stop the wear occurring, I might be tempted to 'treat' all four wheels now, to keep options for the future, but I'm not sure how effective any long term measures might be - as road dirt/grit etc could still get in there and wear away over time.
