I also heard somewhere that exposure to sunlight was a prime reason for degrading tires, so if you covered them when not in use it helped. Anyone hear anything more about that?
You answered your question in the second paragraph. It's mainly the sun that does in tires over time. Rubber will still age when out of the sunlight (garage, barn, etc) but at a much reduced rate.
