Winter tire pressure
I've heard it both ways. Lower your tire pressure for better traction on icy roads. Or, keep them at max to avoid flats in extra cold temps.
Opinions?

This time of year I inflate to max psi. pressure will drop as the temp drops.
IIRC, it's 1 psi for every 10*F. If you go to max psi, say 75 psi (fronts on my superduty), when the temp is 40* and the temp gets to -30* in the winter, there is a 70* temp diff which will be a 7 psi pressure drop.
My approach anyway.

I aim for normal inflation levels, but sometimes add a couple of PSI if colder weather is coming. I'm located in Fairbanks. I would think that the best traction would come when a tire is inflated to the recommended amount with load being considered.
