If anyone is looking for tire storage options, but doesn't have the space at home, I just discovered that Kanata Self Storage will store a set for the winter for $75 (plus tax, I think).http://www.amjcampbell.com/storage.aspx/self-storage/kanata
I am not sure if this is a good deal or if it is a heated space, but I thought I would pass it along. They also have car storage options (heated and unheated) as well.
