I'd have to look again to be certain, but I'm awfully darned sure that the rating on the tire says "cold" beside the number.
That is exactly correct. Also, the temperature does not rise the pressure inside the tire, as much as one would expect.
The most common standard (for radials on passenger cars?) seems to be 30-35psi.
