It seems like that a bit of overkill for a tire that size. I had 2.5" on a 21 internal before and it's fine. You want a bit of that bulge for rim protection. It's mostly noticeable on the Hugo's that I think you have 2.8's on? I tried that fitment before and the sidewall is at the same width as the rim wall.
I am running tubes on all these combos till I figure it out. Will the profile change much going tubeless for tires in the 2.6-3.0 sizes?
Had Dirt Wizards 3.0 on the Hugo and they seem true to size, I'll need to measure the bulge dimensions, but that equates to the rim being roughly 66% of the overall wheel width. I can't find the calc tool, but its right the suggested minimum tire size. Will take better pics of the Hugo today, with the heavy sidewalls of the DWs, the rims seems well protected, though I haven't ridden it in low pressures yet.
