Anyone have a good theory on what is a good tire pressure in winter for snow or ice, deep snow = higher pressure to increase psi exerted to ground and lower pressure for bigger footprint on ice?
Or should we just leave our stock pressure in all of the time. Just curious.

Ex: 05 2.5rs w/ stock wheels 16" and re92's

Whatever the manufacturer recommends is usually a pretty good place to start. Also you might want to update your profile with your location because it also depends on how much snow you see.
