A tire that has good pressure when checked in a warm garage will be under-inflated when it is below zero outside - because tire pressure goes down in the cold. That is why you should do your checks when the tires are cold. Use the maximum pressure amount shown in the owner's manual or on the doorframe as a guide, but never go above the pressure shown on the tire sidewall. Check your spare tire pressure regularly.
