It seems like we're having to fill the tires way too often. At least every
3 - 4 weeks, we notice that the plane has become a real bear to pull out of
the hangar, and that our take-off roll has become noticeably longer. Sure
enough, the tires will be down around 25%, from 40 to 30 lbs on the mains,
and from 30 to 23 lbs (or so) in the nosewheel.

This doesn't seem unreasonable for standard aviation tubes. I've read
several different things about them and what it boils down to is that the
rubber they've always used is somewhat porous (on a molecular
level). There are a few new types of tubes on the market, the most
popular being the Michelen "Air Stop" (I think) that use a better rubber
that doesn't leak. I've heard that they pretty much keep there tire
pressure indefinitely. I believe there have been posts on both r.a.owning
as well as the Cherokee Chat confirming this. I'm switching at the next
tire change.
