my tires finally grew up and are now 42" iroks on h1's, with flat centers and rock rings. Tires helped out a lot, I gained right at 1" at the diff at the same air pressure. I lost some stance though, in front I'm 82 1/2" outside of tires, before I believe I was 88 1/2", maybe only 86 1/2". I measured the rear and was only 1" narrower so I ordered up some 1/2" wheel spacers for now. I also had to cut the overloads off and hose clamp the leafs because of them rubbing the tires when getting just a bit our of alignment. So the question is, does anybody have a good all around number for width? I was very stable for my height before and don't want to lose that, but am I going to notice losing 6" of width? I would like to find another set of H1's and either go pressed centers, or backspace the flat center and use some gussets to get the desired back spacing. I really don't want to run spacers on all 4. Just seems like more to break. Maybe I'm just scared though.
