Will the 16x8 Eagle alloys fit on our trucks, and is the 8 part the size of our factory width, I know its a 16" rim, but not sure of the width, dont want to get into wrong size wheels rubbing my fender wells, would the 17x8's work without spacers, and does anyone know if I use either rim size would 265 BFG's like come on the 3rd Gens for tires work ok, I want some more height over what I got now which is 235's, thanks
