I have a Lauf Seigla frameset coming my way and I'd like to try a few sizes of tires that are greater than 700x40 that I wasn't able to fit before.
In looking at different manufacturers, similar rim inner widths get different recommendations. Then there's of course the ETRTO size chart.
Example:
Zipp 303s = 23mm inner width - Max tire size 50mm
DT Swiss GR 1400 = 24mm~ inner width - Max tire recommendation is 40mm
Reserve 40/44 = 25mm inner width - Website recommendation is 40mm, but several review publications say up to 45mm.
Additionally the ETRTO (maybe I'm adding letters), has a chart there all of the above should be able to handle around 50mm
I'm not advocating for disregarding manufacturer recommendation, just curious if there's other factors I'm missing.
