Here's the long version:
biggest tire I can fit on a narrow rim?
The short version:
Just got a used touring bike for day-trekking. Measured the internal rim width at 13mm - what!?!
Sheldon says I can fit a tire width from 18 to 25mm.
I want/need a 28mm minimum for this bike to work for me, and really would prefer a 32mm.
I want some comfortable tires! 25mm's not going to do that. I might even like a little thread riding hardpack.
If you think I can go with a 28 or 32mm tire, then suggestions appreciated.
