I don't know other than my own thoughts on it.... I had a 700x50 flat on me and come off the rim locking up the ride, the sidewalls balloon out more .. so my thought is wider will help keep the tire on the rim in case of a flat, reduce the ballooning and allow lower pressure maybe?? Made sense to me so if I know it' for really larger tires I'm using the 25 as the minimum .. (note this is me only with no facts to back it up) I run the Velo Orange shiny rims on my other bikes and run 700x38s and my wifes bike is 70x40s on the dyads and haven't had any problems.
That's my 1/2 cent :) Kelly On Wednesday, December 2, 2015 at 9:01:21 PM UTC-6, Daniel Jackson wrote: > > Is there a rule of thumb for relationship between tire and rim width? > > On Wednesday, December 2, 2015 at 9:38:53 PM UTC-5, Kelly wrote: >> >> Well I have he Atlas on my Bombadil, only thing to watch if you like 50's >> is the width. I do believe the Atlas is 25 and dyads are what 22?
