I've got those (25mm width) but on disc hubs. No issues with them whatsoever.
My bro's got CN Carbon 23mm wide 'tubeless ready' wheels for rim brakes from CNCarbon. He's only put about 100mi on them so far, but they seem strong and haven't exploded. Haven't tried running them tubeless though.

Any good? Was looking at some Cosine 55mms from Wiggle but they've been discontinued now. Just for riding around London/Kent/Surrey.
