i live up here in cheyenne, got my 2wd f150, and it came with factory michelens that had the M+S rating on them, my new tires have that on it from Big O,so i hope they handle just as well as me michelins, so far on wet roads they wont even loose traction, if they do good this winter, just gonna start recommending an M+S rated tire, as for wieght last year my grandfather put about 10 80# bricks in the bed of my truck, the truck would almost go anywhere in the snow, this year im gonna just put sand bags in it, and maybe build something to hold them between the wheel wheels, that is depending on how the truck handles.
