Blow out - only cosmetic damage to the wheel rim?

Giraffoto

I've only myself to blame. I made a bad job of seating a new tyre, probably with a bit of inner tube trapped under the bead, and it blew out and took the tyre off the rim with it. The rim - a once-pristine Mavic Open Pro - did a couple of turns on the road, so one of the edges has a whole bunch of little chips and gouges in it, but the tyre looks OK.
So the question - how safe is the rim now? I've used some very fine sandpaper to take down any sharp edges of the chips/pits/scratches, and put the tyre back on with a new tube (trying to reuse the old one is looking like a false economy now), but is there any danger that the less-than-perfectly-smooth rim could damage the tyre?

cracks should form before it fails, you might want to mark any sus bits with a marker and see if they grow with use

I have only ever seen bmx and dj bikes really burst a rim, just keep an eye on it, and chain reaction for a cheap rim (no rush wait for the sale)

clinchers have a wee rib on the inside of the rim, this is what the bead of the tyre locks into (should be ok)

Thanks for that, I hadn't even thought about cracking! I'm not that concerned about the rim itself bursting - it's only a couple of years old and I use only non-abrasive pads - but my biggest concern was that the edge of the rim could damage the tyre. The bead hook is OK - I've checked that - so this has been quite reassuring

I had excatly same issue a month ago , except it was a `gash` along top of a DT swiss rim on my very best wheelset too , and tyre was damaged on sidewall. I very gently rubbed down / fine file the rough area and have used wheel for 200 miles + since no problems at all and rubbed down area feels smooth.
IMO you should be absolutely fine , having checked any other issues eg wheel still true (mine need a bit of tweaking), spoke hole cracks, other damage

Simple file-down and smooth-off the rough bits with emery paper and rim should be fine. I doubt that the tyre giving way wouold have cracked the rim unless the rim was seriously distorted plus aluminium alloys aren't very flexible and would stay distorted
