Default bad valve, bead leak, temp drop, filled tire on hot day
take a spray bottle and spray down the tire looking for bubbles

Default I have been checking over 2 wks. morning pump. late evening check.
When the tires where cold. i seem to lose 1 psi a day. I have never had a bad valve or bead leak. I did just get this tire new from tirerack.

Can i just ask my dealer to check for a nail and or give me a new valve?

Default bent rim?
Could be causing it to leak from the bead.

If you've got steel stems, check them... mine leaked.

Pump it up to 50 and put it into the kids plastic pool. Follow the bubbles.

Default Just fill a spray bottle with soap and water.. spray the whole tire.. find out
As others have mentioned check the valve stem.

It's best to take the tire off the car... lay it flat on the ground.. spray the sidewall including bead... spray all the tread... + valve stemp (cap off obviously)... it'll show the leak pretty quick
