Okay I have a question... I sort of want a dually for towing trailers, and hauling trucks with, but I have a question... I heard that with the extra "wide tires" (2 per side instead of 1) in the rear, it gets more slippery on the roads because the tires float across the snow/ice/gravel/pavement, instead of dig in for traction. In the winter... is it posible to take one of the 2 tires off each side (so there would be 1 per side now) for driving in the winter, then when the snow leaves, put the other tires on? Or how would I go about that? I guess I could get hummer rims (7" or so backspacing) so it wouldn't act funny. But I have never driven a dually... advice?
