I am curious why the topic of snow tires is always so controversial in nature? It seems to me that snow tires like any other tire function differently if ones vehicle is loaded or unloaded , traction control devices , stability control, or other factors come in to play. Then you have the claim get taller and narrower over wider and shorter in the attempt to increase ground pressure of the vehicle. And sure I agree if you want to get to the pavement in deep snow the greater the ground pressure the easier to sink into the snow right down to the pavement. Okay, sure that makes sense... but if you are plowing snow how much snow could you possibly need to sink through in most storms? Ideally speaking your plow should be on the surface and the truck should be driving on clear or nearly clear pavement. Thus, you really only encounter ice and a thin layer of snow.
