In what respect is a wider rim “ideal”? Wider rims are just heavier. Using a narrow rim with a wide tire creates no problems with regard to handling but they are lighter.




That chart is less conservative than many I’ve seen but I often run tires widths that are way outside even that chart. My touring bike has Velocity Deep Vs which have a 13mm inner width. I run 38mm tires on them without issue. I have 17mm rims on any number of mountain bikes in my garage with 2.1” to 2.3” (54mm to 60mm) tires without issue. I’ve been running them since about the time the universe started.
