I agree, that wheel was dropped when the tire was off
Years ago I had a similar situation, I had to have a tire fitted to a brand new front 427 trigo wheel.
The young guy fitting the tire damaged the rim.
I questioned the damage, he tried to tell me the damage was there before he touched the wheel.
My next conversation was with his boss, very stand up guy, he understood what had happened.
He asked for the price of the new wheel and passed a check to cover the price of another wheel, including shipping and tire install. ( very stand-up )
And yes I went back with the new wheel and they did a proper job installing the tire.
Accidents and mishaps happen, its how the problem is taken care of / resolved that shows character.
