I LOVE turning the DSC off in the snow. Obviously I don't do it on busy roads, but when I'm on backroads or in parking lots it's a blast.

I don't know about ya'll but I just got home and pumped air into my tires...
I'm going to let the temps settle an drop the air till it's 36 Upfront and 35 in the rear. It is pothole city out there....

I have to disagree with you regarding that there is a little difference between narrow winter tires and wide winter tires. I have two sets of dedicated winter/snow tires. 275 & 315 on 20s (tires are year old) and 255 on 18s (tires are 5 years old). I can tell you for certain that my X becomes unsettling with wider setup in mid to deep snow. I’m plowing through the snow with wider tires instead of cutting through. And on uneven patches of snow, X would often aggressively shift side to side with wider setup. I switched back to narrower 255s as I feel 200% more confident in deep snow than the wider setup even though I love the look of the wide setup on 20s.

Don't say that around here. Everyone seems to agree that wider tires are better, even in the snow.

I agree with you 100% that narrower is better in the snow though.

Depending on what the wide tire is--in deep snow you are correct, the wider tire will be pushing more snow and be more likely to sit on top of it. There are exceptions to that rule depending on the tread patterns but if the tires are the same just different widths, the narrower tire is more likely to perform the best in deep snow.

If you believe that adding weight to gain more traction is the way to go in the snow, then a narrow tire will be your choice. As you spread a load over a greater area, the weight per sq. inches decreases.

Example if I had a 1000 lb and the area is 100 sq. inches the equivalent psi is 10 psi. But if I reduce that area to 50 sq. inches the resultant psi will be 20 psi.

It isn't the size of the contact patch, it is the shape of the contact patch.

Narrower tires will cut through deeper snow because of a shorter leading edge, not because of the ground pressure. Ground pressure will be very similar to tire inflation pressure.

I can see that. Ruts, or overly wide tires such as 20", will not cause tires to perform as well but on packed snow wider is not such an issue. And on the icy surfaces we get here, wider is often better since there is more lateral grip,

Are your 20" tires the same tread compound and rubber compound as your 18"?
