I have a set of General Grabbers that need replacing. It caused me a few embarrassing moments in the middle of the snow storm here. Expedition is more of a passenger vehicle than an offroader so I suspect chunky tires won't look good on it. At the same time, I don't want to go with street tires either. Need pretty good snow traction. I was looking at the Goodyear Wranglers. It does have a rather aggressive thread but not too much. So what is the middle ground?
