That is the issue, echoed by many tire shops.

It is a pretty brutal procedure, even with the correct equipment and training. The problem, like running on the tires when flat, and getting a repair, you can't necessarily see the damage. Removal and remounting could do damage and you won't know if the structure has been compromised. The risk factor is increased for future tire failure.

I'd certainly not be tempted to remount run-flat tires on a seasonal basis.

I wouldn't even do it with normal tires, let alone with run-flats. Plus with dedicated wheels you have the chance to have a decent summer wheel set and an appropriate wheel set for winter driving. For example, a smaller winter rim allows a higher aspect ratio and a narrow tire section for optimum winter performance.
