I would highly suggest anyone in for routine service make sure to note boldly on the paperwork NOT to do the tire swap. I would make sure the SA knows it and go as far as to watch him write it on the ticket. The Service Department is reimbursed for this labor and will want to do the work, so I would pull out all stops to make sure they are not to do the optional tire swap. If there were tire wheel locks, I would take the key.
