Looks like the snow and ice is headed my way, so I'll go ahead and mount my $2K worth of studded snow tires and rims (I have a 4wd Silverado 3500HD dually), so 6 wheels in total. I live in the middle of nowhere, so when it gets ugly, it tends to stay that way. Many of the roads branching off of mine have signs that state "No Winter Maintenance". So 6 studded snow tires and 500lb of rock salt in the bed will let me get around.
