Many drivers want a tall skinny tire on a 17. 285 is not skinny. 285 will not work on most duallys either. 255 would be a good off-road width, not snow or ice maybe, but dirt n rock, and would be more efficient on highway. Im still waiting.The Mastercraft CXT comes in 255/85r16 and 285/70r17.
Your ideal tire reminds me of the old Dunlop Radial Rover RT. I really wish they hadn't discontinued them back in '08 or '09.Designing the perfect tire has eluded tire makers for decades, because no one tire can truly do everything well. I want an all terrain tire because like most people, most of the miles I drive are on paved roads, and I need good snow traction as well. However, I also want a mud terrain, because slick mud is one of the quickest ways to get stuck, and here in the Midwest, there never seems to be a shortage of mud around.
My idea is simple, combine the two. I took my inspiration off the BF Goodrich line using the KO2 tread in the center, and the KM2 tread blocks on the outer edges. Don't see why they never offer a tire like this.
