So I'm about to head into that long, cold, seasonal affective disorder causing time we know in Michigan as "winter". I've got a set of Sumitomo HTR Z III's which I'm going to need to store for the next 4-5 months. Anyone know if they need to be stored indoors/out of the cold? I've heard extreme cold is very hard on soft compound tires, but don't know if that extends to storage as well. Unfortunately, one of the things that helped me convince my wife I needed the nice new shed last fall was that I could store my "summer wheels and tires" in it, so "we need to store them in the basement again" might not be a big hit.
