Best Answer

You should check your tires every month or so, because driving with low tire pressure can cause excessive wear of the tires and poor handling. In cold weather, the air becomes more dense and the pressure falls, but this isn't a significant factor. As you drive at freeway speeds, the flexion of the tire causes heat anyway, so even on a cold day, the pressure is probably fine.

Air is more dense when it's warmer, and less so when it is cold.
