I have a rim with an 18.3mm internal width, and a 23 tires measures out to 26.5mm when inflated with a tube. Would a narrower rim cause the tire to "bulb" more, less, or are there other factors beside internal rim width that impact this?
Thanks!
as a guide, my Rubino Pro clinchers were ~24mm on 15mm internal width rims and ~26mm on 17mm rims. Stands to reason that, in general, a greater separation of the beads (ie increased rim width) will result in an increase in overall tire width, although it might not be that noticable
