How to calculate max/min tire width for a rim?

I have a rim that has no sticker/indication of what tire widths it will accept. How do I figure this out?

Measure the inner rim width. Ideally, you'd use a tire 1.45-2 times that in width. In practice, you can get away with going a little wider.

I figure the typical limits are about 1.25-2.5 X rim width. After that, you're on your own.
Of course, someone will disagree, even if they're wrong

Sometimes it doesn't matter because there's only one size for that rim, such as the 590-597MM rims.
