I have had a long-standing policy of not purchasing Goodyear tires. I fell in love with the Duratrac and chose them over the BFG All-Terrains for my truck. Mistake. For about 1000 miles, I really liked them... then the vibration started. At about 70 MPH, the whole cab vibrates -- I mean, if you leave your shades on the dash, they'll vibrate right off. I've checked the tires for abnormal wear, even removing any rocks larger than a pebble (think pencil lead), but still, the vibration persists. Driving in the rain is okay in terms of hydroplaning, but if I am starting from a stop (backing into the driveway, for instance) and it's been raining, I actually have to put the truck in 4WD in order to avoid spinning. Absolute junk. Never again.
