Gear Talk / Matching tire width to rim size.
« on: September 24, 2004, 04:10:16 pm »
How can I know the largest width tire my rims will safely accept for touring with a load? My recumbent bike came to me with a 28 mm tire on the rear wheel and at the builder's website it list the rear wheel as 28mm. It seems I read somewhere that you could only safely move up or down one tire size which suggests a 32 mm is as large as I could go. However, I no longer remember my source so I am relunctant to trust what I think I read. Can anyone advise?
