Well I just had my brother take my truck out of the garage, where it has been resting for the winter. I had to roll the front tires onto two 2x4's to get it high enough for the jack to fit into the location that Ford says to jack up the truck. In a real life situation where the ground is not flat or solid, I think it would be near impossible to put the jack in the prescribed location and raise the truck safely. I found some 205/40/R17 tires that made the truck low enough to drive out of the garage. Now the LT 275/70-R18 tires and wheels are on the truck, and it is ready to roll.
