I'd personally wait for an inspection when they swapped the cover. At my 14k mile 2nd tire rotation I talked with a guide who said it was ok to have discount tire do rotations and not come back until the higher mile services if everything was going ok.
Just so you don't get bashed, Rivian sales the complete setup with tires for $3700 in the shop. I think they discontinued the brights and have them discounted.
I don't think the depreciation is as bad as it looks. I think Rivian is like Tesla with trades, if we're going to screw with it we might as well make some money. 18k miles just brought 73,400 at Manheim Auction. 12k miles brought $81,200
