I've posted before, but I had a "brand new" spare trailer tire that I kept in the trailer or in a garage during that time. I finally needed to use it about 6-7 years later. It still looked like new. After only a couple of thousand miles, it peeled like a banana with the rubber simply separating from the cords. I drove on the steel cords for a couple of miles before finding a place to pull off & change it.
