here's one.
Keep in mind that there's plenty of fudge room beyond the "recommended" range.
Over the last few years there's been plenty of published info about the implications of tires that are either too wide or narrow for the rims. If you have time to kill, you'll find plenty of reading search "bicycle tire width vs. rim width".
I've ridden a lot of miles with rim/tire combos that now know are so "wrong"! Especially big tires on skinny rims. (I guess I am a sick one. I love steep, rough downhills on very fat low pressure tires. Love the grip on turns. Apparently I've rolled them, crashed, woke up stunned and ridden on, completely oblivious. A bunch of times. And I am still clueless.
My current blasphemy is 35c Paselas on Mavic Open Pro and Open Sport rims with 60 psi, less if IU am going of pavement.
