Like I didn't know your favorite tip or trick already in the 1970's. But OK, nobody so far has tried this idea, with good *or* bad results. I'm kind of surprised, you'd think people would have a little more imagination than fixating on the tire as the source of the problem. But maybe I'm the idiot and am about to ruin a perfectly good set of wheels. I think I should probably roll out the new wheels and a few of my old ones to see if there's an actual difference in circumference at the bead. If not I better think twice before modifying anything.
Anybody want to make a prediction?
A helpful response would be "I know a guy who tried it, got his tires on just fine using his pinkies, but had a blowout and died on a descent". Or "I saw that some cheap rims just have very rough grooves along the braking surface and those might be what's making it so hard to work the tire on. Maybe you just need to knock those down a little bit on the side".
To be fair I should have mentioned: these are 700cx25mm *used* road tires going onto brand new Chinese rims.

try some different wheels. i mentioned it in a post above with tires i had that especially difficult to mount. and, what you're dealing with quite common when mating different tires and different rims as tolerances will vary with either. it drives the tubeless crowd to madness
thing is, tires do stretch. it would be better to wait for them to do that than ruining your rims....because you will. that edge is just as strong as it needs to be and will still fold under a rock and low enough tire pressure. it only gets more prone by taking off more metal. furthermore, as someone mentioned, you stand the chance a tire popping out of the bead in the future.
