Air Pressure in Winter Snow Tires

Last year I mounted snow tires for the first time in over 40 years of driving.
Here are two threads in response to questions I asked just like yours:

Winter tires aren't very popular in America, but they are in Europe, with modern traction and stability control you actually don't need AWD these days, especially in a FWD car with sufficient ground clearance (highlander, venza, escape, etc). That's why in the Prius I like to upside the tires a little to give me that extra little clearance over the snow.

Here's a survey for someone not sure if they should buy winter tires:
Do you live in northern climates and care about your life?
Do you live in northern climates and care about your passengers lives?
Do you live in northern climates and want to avoid an accident this winter?
if they answer YES to any of the above they need to buy winter tires.

The reason winter tires aren't popular is actually the tire manufacturer's fault. If they gave them proper names, such as Cold Temperature tires (instead of winter tires), Hot Temperature tires (instead of summer tires) and Mild Temperature tires (instead of all season for cars or Mud & Snow for trucks) I think people would have an easier time understanding the limitations of so called all season tires.

Here's the nail in the coffin for all season tires: The jack of all trades is a master of none!!

 

I run my studded snows at 40/38 about the same as my summer tires.
