I see no value in trying to get a presto tube to work in a rim made for a
schraeder tube. Seems like just asking for trouble.

Sometimes there is value. On my road bike I bought a replacement rear
wheel and it was drilled for Schaeder but the front wheel is Presta. I
would prefer to only carry one tube.
