Help - Paranoid Tire/Rim Question

I received my 18 x 9/10 FR500 rims and 265/285 tires. The shop I took them to for mounting had a problem with their balancing machine so they took them to another shop. Those FN idiots mounted the 285s on the 9" rims and 265's on the 10" rims. They are on hold until tomorrow because they also scratch on of the rims trying to get the tire off.

My question is, should there be a problem with the 265's being mounted on the 9" rims since they had already been mounted on 10" rims? I don't think so, but I guess I'm just paranoid given my ordeal of the last couple days.

Oh, I was plenty pissed and I still am. When they called the owner back in he acted like it was no big deal, so we had issues from the first second. He was like, "so you don't want the rim", of course may answer was f**k no, not like that.

Thanks for the input so far, I had not even thought about valve stem alignment.
