I have heard that aging tubulars was a type of vulcanizing, in effect making the rubber a bit more durable, but I've never been able to determine if there is any validity to this or not. It was a very common practice by just about everyone. My brother stuffed tubulars into a cloth bag and hung them from the basement ceiling in the late '60s & early 70s, and I also recall an article about a visit to Colnago's shop and the basement contained stacks of Gommitalia tubulars being aged for later use.

The glue used to attach the seam tape and the rubber had to "gas out" for about half a year to achieve maximum durability. It is not necessary for modern style tires like Contis. In fact, these will have their best performance when new and degenerate over time; especially the thread will lose grip and become prone to pick up debris. It is possible to slow down that unwanted ageing by storing tires properly, protected from humidity and light.

I have found that also true for Veloflexes. I'm not 100% sure for Dugasts, since they seem to be built in a very classical manner.
