For those considering hoarding some tires for later years, don't forget the degrading effects ozone has on rubber. It's hard to escape since it is present everywhere in the atmosphere. I don't know if it is practical or if there would be any benefit, but some plastics manufacturers (Stihl weedeater blades) recommend to "Always store thermoplastic blades in water. The moisture absorbed improves the ductility of the thermoplastic and thus extends the life of the blades." I don't know if storing tires in water would help or not, but they would not be exposed to the atmospheric effects. Also, I'm unsure if the thermoplastic benefit would be applicable to the rubber/mystery material that our bike tires are made of. Just thinking.... food for thought...
