What advantage is there in aging tubulars?
None! The aging concept arose from the same source as the "steel frames need to be replaced because they get soft with age" concept. Both were intended to improve sales during the off (winter) season by bike shops with too much inventory on their shelves. Tires oxidize, outgas, and polymerize from ultraviolet light. The concept of a tire manufacturer making a tire that cannot be used until ripened for six months from the date of purchase is ridiculous. Tires can be made to any specification at the factory. Tires are most flexible and durable when they are new. They don't improve with time and exposure to heat, light, and oxygen or ozone.
"Over-aged" tubular tires, have crumbling hard brown latex on their sidewalls that exposes separating cords directly to weather and wear and they have treads crack when flexed. Considering that this is a continuous process, it is hard to explain where, in the time from manufacture to the crumbly condition, the optimum age lies. The claim that tires are lighter after aging is true. Their elastomers have evaporated making the tire brittle and weak.
Purchasing tubular tires in advance to age them is unwise, although if there is a supply problem, tubular tires bought in advance should be sealed tightly in airtight bags and kept in the dark, optimally in a freezer. For best results, use new tires because aged tires are only as good as how little they have aged.
