Winter tire PSI?

Quick question...
I'm running Blizzaks during the winter. On packed snow and ice is airing down gonna help at all with traction?
As I understand it, airing down helps with deep snow by creating a larger footprint. Was talking to someone the other day that said I should be keeping winter tires a little over-inflated for traction on ice.
Which is it? What PSI should we be running on ice and packed snow?

 

Must be a pretty good question.

 

I was always told the wider the tire, the worse traction you get. I heard skinnier tires are better for the snow cause they cut in better then wider tires do.

 

For hard packed snow/ ice, I would think that a higher tire pressure would be better to decrease the footprint slightly and increase the pressure on the tread area.

 

for hard packed snow/ice, i air down. fresh snow, skinnier track is better. my $.02

 

You either want tall and skinny or fat and underinflated. If you're sticking to roads, tall and skinny (normal pressure) is what you want. If you're going off the road and want to float then you want fat tires and underinflated. I normally run normal tire pressure all winter. If I have a long run that I know will be crappy or unplowed I'll drop the pressure a bit.

 

Good deal, thanks for the help guys.
