Tubular holding tire pressure?

This may sound like a stupid question, but I just want to check before I replace the tires.
Are tubular tires supposed to hold air as long as clinchers? I recently bought a pair of 808s that both had glued tires. The guy had them pumped at 140psi, but within a matter of 4-5 days they had lost all their air. I tried airing them up last night, and they had probably lost 10-20psi since then.
Is there anyway to fix the problem, without replacing them? The tires appear almost brand new.

One has a zipp tangente the other has a Vredestein fortezza pro. Not sure if either of those have latex tubes.
Hi,
I have a question too.
Do I have to put air all time? or leave as is and when I need put air and go ride?
Because I have a disc and will use only once a while and have to off 2 month.
This case, do I have to put air least once in sometime? or just leave it and put air right before I need to use?
thank you guys.

I don't see a reason why you should put air in consistently. If you are, I imagine you might wear the tube out just slightly more than letting it sit months at a time.

geoff is right
i loose about 10-15 psi in 2 days, when i inflate them at around 110psi
the lower the pressure the slower leakage.

These are my first tubulars, and they already came pre-installed...
Is there a way to check the valve extender seal without detaching the tire?

If you are not losing much pressure in the space of a couple of hours I wouldn't even bother.phourgenres wrote: Is there a way to check the valve extender seal without detaching the tire?

Conti tubulars don't use latex tubes.denzity wrote:I get the same problem with my Zipp 808. At first I thought it was the valve extender, but found that it's actually the tangente tyre. I have conti GP4000s on my other tub wheels and they don't suffer from the 'leak'.
