Even those need to be managed to use up their lower tread depths in the better conditions. So multiple wheel/ties sets need to be on hand.
This obviously mandates owning vehicles for a decade or so. No leasing here.
and most people here do not have four wheel drive vehicles... AND they have no clue as to how to drive in this weather. Those all weather tires do not give you jack when you are on roads that are nothing but glazed ice.... that’s true even in snow country....even chains may not give you enough traction
And again I say you obviously live in an area that is subject to sever weather.
