Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

No, to my knowledge there's no user guide to rim and tire fit and tolerance. However, certain rims have reputations for tight fits, as do certain tires. Obviously combining a tight rim with a tight tire is asking for it. I look for rims with deep center wells, and tires that don't have too much below the dead or hook bulge, then before actually mounting, double check by mounting one side without an innertube.

I've also gone in to shops and tried a few tires on rims where friends had issues (I ride tubulars). I admit that I might get some slack because I have a business relationship, but I expect that if one were to bring in a wheel and ask to check various tires for fit, most decent shops would be OK with that.
