Tim- St. Sheldon's dogma is pretty conservative in the regard of "proper tire width for a given rim width". http://www.sheldonbrown.com/tire-sizing.html (Width Considerations chart is the red/green one most of the way down the page)
However, many folks have ridden many millions of miles on 2" (54 mm) tires on 17 mm internal rims -- because that was pretty much all there were at the dawn of MTB/ATB/Trekking bikes. The risk with a too-wide tire is the same as that of an under-inflated tire: risk of the tire folding over when turning aggressively. Keep your PSI above ~25 and you shouldn't have that problem with RTPs on an Atlas rim. On Sun, May 6, 2018 at 11:58 PM, Tim Butterfield <timbutterfi...@gmail.com> wrote: > > I just looked it up.
