From my experience around here most deep snow wheelers run swampers work fantastic when your pushing through 4+ feet of snow .
Any giant tire works better than a stock size when the snow is that deep. But conversely none of those people seem to have ever tried a snow tire in winter and seem to have no idea what works better in every situation other than virgin trailbreaking through deep snow.
On a wet mountain road or snow packed road I would take a crappy set of all seasons before swampers. I'm speaking from actual experience too. They are awful tires from any other metric except rock crawling and super deep snow and mud. By awful I mean there are tires that do the extreme mission with way less worse road cold and wet performance. They are not all that relevant with the last 5-8 years of tire tech.
They had there place for a long time. Swampers and Ground Hawgs were swell in 1985 but in 2019, no way.
If anyone ever tried snow wheeling on actual SUV spec snow tires they would light there swampers on fire, save for extreme situations like where breaking trail on 40's trumps better traction in literally every other scenario.
