What do you mean? 23s have been done for months. Shipping of 24s started in the fall. If anything you'd be lucky to get a MT 24 by summer before they switch you over to a 25.
Of course they aren't going to touch when they aren't being compressed. Ie hitting a bump.
And when I said seated I mean. Are they installed correctly.
OP has a legitimate question. There are some shitty tire shops out there. Don't need them damaging my aftermarket wheels. Some after market options are expensive and not wanting them scratched is fair.
