Rode today in temp approx. 30 deg. and tires felt underinflated. Recalling my limited chemistry knowlege, I considered that the pressure I put in the tires indoors may have lowered itself due to the outside temp causing the air molecules to constrict. Any thoughts welcome.

Seen it happen in the front tires of our Front wheel drive Cavalier LS Sport today.

Air it up outside SLOWLY so the air you put in doesn't heat up too much. That should work.

A little off topic but still related:

...if you're riding the trails in the snow you should be able to lower your tire pressure down to around 20 psi and have no problems. It seems while riding on snow covered trails your chances of getting a pinch flat is reduced. I did this last winter around 6 times and I was using Conti Explorers with tubes and I weigh around 180 lbs. Obviously doing this helps you get better traction and gives you a more comfortable ride. This winter I look forward to using Conti Vertical tubeless tires.
