Yesterday I rode 55.68 miles on a bike with tubulars. When I was returning home with just a few blocks to go and in the next to last turn, the front tire went flat and lost most of its cornering bite. Fortunately I wasn't going very fast. I stopped, checked it over. Yep, it sure was flat. I rode the last few blocks as it was, leaning back to shift my weight from the front to the rear and avoiding any bumps (it was smooth pavement). Tire and wheel survived. Later I put some Stan's Tire Seal and a bit of air in it, spun it around a bunch, pumped it up again. It held air. Today I rode it 36.35 miles with no depressurization incident.

How long do people leave tires on unglued rims to stretch them? I am putting some Challenge Elite Pro 25mm on, they went on the unglued rim pretty easily. (easier that the tufo s33's which were my first foray into tubular), I did remember to be patient, put the tire on slowly pulling it out so to speak.
next up will be doing the glue, I have used tufo rim tape before.
the fun thing is that after I fix some broken spokes i will be able to do a direct compare between the Challenge Elite Pro 25mm, the tufo s33, and even some michelin pro4 clincher on the same bike

I have been known to let them go 6 months as part of the aging process. You are going into winter, are you likely to ride them soon? Let them go a month unglued, glue them, then leave them to age in a darker corner of the basement. Come spring you are ready to rock and not roll them off the rim.

If they went on easy, you are ready to glue. Continentals are a bear to mount for a stretching session and after weeks of stretching at 100psi, they are still a bear to mount for glueing.

As for glue, I finally ordered a small can of Vittoria mastic and bought a bunch of small inexpensive artist's brushes from the local hardwrae store. Applying glue to either tire or rim with a brush is so much easier than squeezing it out of a tube. I've re-used the brushes once or twice but will most often just toss it and use another. Prepping tires was never so easy.

Stan's didn't hold. Oh well, got a couple more rides out of this old tire. Been glued on for a year - judging from how hard it was to get off, my glue jobs are top notch.

I usually just let them stretch for a day or two. If you can get them on and off the rim without too much trouble then doing the same once you have applied glue isn't so much harder.

Packs of acid brushes are VERY cheap from harbor freight. I usually use two on a tire gluing session. I only leave the tire two or three days to stretch and not have had an issue even with my go-to sprinter tires. What is the benefit of leaving a tire 'age' for months?

I'm not sure, but I know some of the CR folks indicated that certain tires did require a fair amount of aging before use. Maybe something to do with curing of the solvents used in construction?

Specifically and FWIW, I remember that Continental sewups had a reputation for the tread rubber getting harder and more flat resistant after a few months. This was in the early 80s when they first started selling them in the US.
I generally just stretch a tire overnight, if I bother to do it at all.

I tend to agree with this for the most part. One caveat: a few tires BITD did get noticeably more flat resistant as they got older. Mostly it was trivial and not worth bothering with. As mentioned ^^^, at the same time the casings were getting weaker though, which is more important. Also, tires now tend to have flat resistant belts so aging is even more pointless.

I found way back as I did not have the cash flow to buy much for future use, that if a tire made it 6 months without puncturing, you were in for many trouble free miles.
(in casual report with an aged tire, one just felt less road debris clung to the tire when you reached down to wipe it off )

Just once met a shipment of hot off the presses Clement tubulars. They stank of solvent. Could not be sold. Moved them to most remote part of shop and waited two weeks before bringing them back out. Those tires would have benefited from aging. Most of the time distribution channels were slow and creaky and tires had some sort of aging before customers saw them.

Can we feel the difference between nice tubulars on GP4 vs. GL330? I ask because I have a pair of Vittoria Corsa Competitions to mount. I can do it right away on some GL330 32 3X on 7400 hubs or I can wait to wear out my Gatorskins currently mounted on GP4 36 3X on Record hubs. This is only a problem because I wanted to use the GL330s on some 7700 hubs. So, I suppose the real question is, If there is a more appropriate tubular rim for a 7700 bike, what is it?

Thanks jim ... great to see old friends and meet new ones. Other life-stuff had my attention for a time, but it didn't keep me out of the bike shed — and gluing cheaper tubs ))

tubeless or not, the future is unlikely to be glued on.

So, to answer: a 20 second moderately forceful stretching with my body, then four days at pressure on the installed rim. I rarely do the body stretching, because once I heard the faintest sound of a tear while performing it. I didn't hear any thing from the tires, this time. I only chose to do a body stretch because I could not make it budge onto the rim with the usual "stretch it on" technique.
To add: I see what I did as stretching rather than aging. As far as I know I've never aged tires in any "formal" way. That means to me, I not only know when I put them up, but I know how to tell when to take them off. I have old tires that are unused (these Gommi's), but if aging requires having them on rim so that they become shaped to the form of a tire rather than a folded ribbon, I have not done that. I have also installed freshly bought tires. I can't say I see any difference in the behaviors of the tires. I am also doubly a sinner because I have a furnace with a large fan motor within 10 feet of the Bike Room ... mea culpa! But I have not observed a problem.
