About the snow, they prob suck in the snow, the wider your tire is, the less traction you will have, because you tire will have less weight per square inch, because there is more tire on the road. For mud, wider is better; for snow, narrow is better. The only thing that might possibly increase your ability to drive in snow with those tires is that the actual diameter is larger than stock, so you will have less torque at low RPM's, making it a little harder for your wheels to spin. If you are concerned about snow, I'd stay away from the 225's.
I've gotta disagree here. At the same air pressure, say 35psi you have the same number of square inches of rubber on the road. Let's use nice round numbers and say we have a 2800# car with ideal weight distribution of 700# per corner. A tire with 35psi will put 20 sqin of rubber on the road.
If we have a 4" wide tire, you will have a contact patch that is 4"wide x 5"long. Go about 25mm wider to a 5"wide tire and you have a 5"wide patch only 4"long.
It is harder for the wider patch to "cut" through the snow, so it simply rides on top, or has to push more snow out of the way. The narrower tire acts more like a tank tread, providing better traction in the snow, and probably rain also since water being evacuated from the tire has less distance to travel.

Yes, I did pass my college Physics courses.
