My Son has an 07 FX2 with the Triton Motor...He presently has a Wide Tread Tire ( 275 / 55R / 20 ) the tread design has groves on the edges with a 4" semi bald strip down the centre...The Trucks seats leaning towards the front. Which to me says absolutely no weight to the rear wheels and yes it's hopeless in the snow, just seating in the truck and saying the word doesn't help...The Tires are supposed to be an All Season but judging from their performance I say it ain't so...Having said all that, any suggestions on Tire Brand and Size. The Truck seats more than it's driven as my Son's job takes him away from home 6 wks at a time....I had thought of adding weight in the box but I'm afraid of that coming loose and causing more grief....Thanks
