Covering tires inside?

I'm lucky to have a place to store my motorhome inside for the winter, although not heated at least it's in out of the winter weather. In the summer months when it sits in our driveway I have covers on the tires to protect from the sun. I was wondering if I should cover the tires when stored for the winter while inside? Do you cover your tires while your motorhome is stored inside? Just curious what others do. Thanks
