it depends man.
idk if 2 psi will change much..... but widening your foot-print(
contact patch), can increase the 'bit' from a stand-still, but it can also act like a snow shoe, keeping you on top of the slick surface when driving, causing hydroplaning on anything other than dry road surface. you want the skinniest profile when driving through the snow, so the tire sinks down to the ground easier.
side note: decreasing air pressure to gain traction from a standstill, is in fact a good idea when your stuck. but if you drive that way, it will actually cause the air pressure to increase(if driven fora while), by causing the rubber to flex more with the larger contact patch- generating heat, causing the air pressure to rise faster than normal.

yes and no. yes for obvious reasons(snow is slippery lol) and no, if your comparing snow tires to all-season tires. snow tires have thousands of little slits that keep the rubber from staying hard. since rubber gets hard when cold, the slits allow the tread to stay flexible = increasing grip on the contact patch.
