Just FYI to the OP; You don't want to air down in the snow, that will make you ride on top of it and decrease traction. If anything you want to overinflate.

The best example I can think of is rally cars. When they do a snow run they use hard compound skinny tires.

Heh Heh, you can't compare 2wd race cars on hard snow to jeeps in 5' of soft snow

You airdown when you're trying to drive, in over 3' of new snow and that does make you float on top--it's a requirement if you wanna go somewhere and not spend all day digging/stuck-

Of course you won't airdown in 1 to 2 ft of snow, just drive carefully and clean the diff. humps when forward motion stops, backup, shovel hump, drive on

Fun in the snow-

Hm, I guess it makes sense.. I usually aired down but I suppose its normal to stay at regular PSI. I was thinking more for rainy season, does it help traction when the roads are wet? More tire surface that way..

Under inflating tires increases hydroplaning.
More tire pressure keeps the tire a contact patch a little more round, and it pushes the water toward the outside edges of the tire as it should. Too little pressure and the tread gets concave, water collects in the center of the tread pattern and you are more likely to hydroplane.

Take more time to get where you have to go. That's winter driving preparation.

Don't air down. If anything add air, cooler temps cause psi in hour tires to drop slightly.
