I try to keep the tires at the recommended max of 80psi. I can pump them to
80 ride, come back several days later and the pressure has fallen to around
40 or less.
One tube is only 1 year old and the other is 3 years old but they both lose
pressure. I'm beginning to suspect a reduced quality of the tubes in
general, but I will double check the valves to make sure they're tight.
Thanks all.

I normally ride about 100 miles a week and like to keep a high pressure in
the tyres, which are 700x25 at the moment and I pump them up to just over
100 psi. Usually after about 2 weeks I feel as though they need a bit more
so I give them a bit more, but it's usually not much.
In France I pumped them up after about 10 days. I'd lost quite a lot of
air quite suddenly from the front, but it turned out that the valve had
loosened up a bit and I didn't have to do any patching.
How old are the tubes on yours? Maybe you have a slow puncture. Life's too
short to mess around with that type of stuff when new tubes are so cheap.

Along similar lines I'm wondering how often bike riding list members have
to inflate their tires. I have a few year old Trek with tires that need
reinflating every few days.
Don't remember having this issue with my last bike, a 24 year old
Cannondale or way back when I was growing up.

Thanks, guys. I'll check out Sheldon Brown's site. Steve, the
discussion at that link spans the whole range of opinions, from "no
problem!" ro "almost certain disaster."
Meanwhile, I closely examined the tire in question, and there is a
small area where it has started to delaminate along the bead. Since
it's off the rim, I don't know if that is where the bulge was
appearing or not; but for now I think I'll just get another tire.
Bob, the next time I get a flat I'll pop on over and check in with you
and Chris!

Short version: The rims are "hookless" dimpled Weinmanns. Is there a

Could you try a tubular? They're tires with the tube sewn into the
casing and are normally glued onto the rim. Still quite easy to get as
many racers swear by them. I find them expensive and fiddly and am
thinking about selling my tubular race wheels to get some clinchers.
Failing that, perhaps you could find more info on Sheldon Brown's
website. That's a treasure trove of information about bikes.
