inflate tire when "COLD" - but should I do it in my garage or outside?

[ToyotaLexus]

I know I'm supposed to inflate my tires to the proper level
when the tires are cold.

However, I'm confused as to what "COLD" really means.

For example, the temperature in my garage is 60 to 65 degrees in the winter.
(when the outside temperature is about 35 degrees or lower) This is about
35 degrees of difference. Based on what I read on TireRack's website, that
every 10 degrees is about 1 PSI... so 30 degrees is about 3 PSI. That seems
like a pretty big difference to me... Should I check the tire pressure when
I wake up in the morning, while the car is still in the garage? Or should I
leave the car outside and check the pressure in the morning?

Also... weather has been pretty crazy lately... last week it was in the low
70's... but two days ago it was 25 degrees.... then this morning it went up
to 62 degrees again.... with such a wide temperature range within days,
should I check/adjust my tire pressure on a daily basis to compensate for
the changing temps?

Thanks for any advice!

Cold tire pressure's definition also includes that it is not driven for more than 2km If I remember correctly, as that will also warm up the tire and air inside.

cold means the vehicle hasn't been driven. the manufactures pressure rating accounts for airing the tire when cold then warming up to optimum pressures.
unless you experience abnormal steering or breaking conditions, i would just insure that they read the same. either way, it would be unsafe to run tires below the manufactures min rating under any conditions.

* some vehicles run a slightly lower pressure in front. so the fronts would match and the rears would match.
