The old Coats machines could damage a wheel this way. The wheel mounts upside down over a spindle. A cone screws down onto the center of the wheel to hold it. A blade is lifted up over the tire to the wheel and activates downward to break the bead from the wheel (while another blade breaks the bead on the other side). Then the inside of the tire is pulled up to allow a bar to wedge between the outside rim of the wheel and the inside of the tire. The wedge attaches to the spindle and then rotates (drags) around the wheel. Repeat to get the other side of the tire off.
Flip the bar over to its forked end to put the new tire on.
Lots of room to damage the wheel.
Better to find a shop using Hunter equipment. Especially for road force balancing ... Few shops have the balance machine. Find one and you've most likely found a good shop.
I'm not saying the damage was done while changing tires. Just that it's possible. If I was placing a bet I'd go with a car wash.

I recall the auto dealership I worked for back in the 90's using a machine that worked exactly as you described. As for Hunter machines, do you know if ALL Hunter mounting machines of the touchless variety?

Yeah I'm sure this is from a car wash from previous owner. The tire mounting question is kind of a separate thing that I combined into one thread.

I used to travel a lot, modifying and updating industrial machinery. I always appreciated the customer that wanted to look over my shoulder and examine my work. I knew they would appreciate my efforts and be happier for learning what I was doing.
If your mechanic doesn't feel the same they may not know what they are doing.
I leave the hubcaps on when I drop off my wheels. It's a test. Check to see if they put the hubcaps back on pointing to the valve stem. If they did compliment them for it. They will remember you next time.
And leave a $20 behind for a pizza when you pick up your new tires. Their work is tough, especially in the heat of summer.

I don't know of any that aren't. But I can't prove a negative. I would ask to see the equipment. Let them know you are curious and involved. At the very least you should get better service.

As said already - car wash track or concrete damage. What size wheel and tire are those. The tire looks a little narrow for the wheel width. Tire size is obviously on the sidewall and of a Porsxhe wheel, width is embossed by the valve stem.

OEM wheels with OEM size tires (295s). I just put 305s on them a couple days after that pic was taken. Both sizes were in spec for 2009 C2S though I am not sure if the stock wheels for that year varied in width....don't think they do though, These are the "sport wheels" (split 5 spoke), I think the call them.... the ones everyone seems to like. Silver painted, not the ones with the machined faces.

Those look like Turbo wheels to me...

These are mine - OEM with 295s. Just put sport cup 2 on them (305s) and will be using the OEM wheels as my track setup and I have a set of BBS E88s coming that I will run on the street.
