Maybe 2x4s were once actually 2" x 4", don't know, best I remember
is 1 5/8" x 3 5/8". They were that way for many years, then went
down to 1 1/2" x 3 1/2". That's OK, no problem but - apparently -
pressure treated 2x4s are still 1 5/8" x 3 5/8". At least the
ones
I just bought and chopped down to size yesterday are (I'm making
some cabinet plinths).
Now, 1/8" isn't all that much but it's enough to screw up my plans
for the rest of the cabinets which means I either have to revise
the plans or skinny down the PT. I'll do the latter but I sure
wish they would decide what size 2x4s should be, PT or not.
I guess I should ask a question, not just rant, so I will: Is
there
some reason PT 2x4s are bigger?
For the further education of a novice, could you explain what sort
of
cabinets you are making that require 2x4s and why you have chosen
pressure treated? One more thing: When you "skinny them down", won't
you be atomizing a great deal of allegedly poisonous stuff into the
air? Standard disclaimers about my overall ignorance apply. 
And another: How "deep" does the pressure treating go? If you need the
critter-resistance of PT lumber, won't you be reducing it, on two
sides
of each board?
Ugh. I see now that I missed the word "plinths". I assume these will
rest on a moist floor. But I'm still interested in the rest, if you
wouldn't mind.
See my first response. The floor isn't "moist" but it IS concrete. Which
means that some dampness will penetrate it from the ground upon which it
sits.
Now, plain old white wood would likely be entirely satisfactory,
especially given the length of time I am likely to be in this house, but I
elected to use the best available to me. If I had a roll of tar paper
handy I probably would have used all WW on a layer of it.
Skinnying it down just involves ripping off 1/8 from the 3 5/8 dimension.
That edge won't be on the floor but would still be fine even if it were.
