My experience is that in the era of great tubeless compatible rims, for CX in particular it's not worth messing with conversions of non compatible rims. The one time I tried ages ago my tire...

15% variation on a side is okay, 10 is better and usually pretty acheivable. Park has a neat web app for mapping tension at parktool.com/wta.

It probably isn't likely to significantly affect the ability to true the wheel, and isn't particularly more likely to fail, but it doesn't look great. Personally, I'd probably replace it when...

Freehubs aren't interchangeable between brands. Replacing the hub requires a new hub (high end hubs range from about $120-$600), and will probably require new spokes. Basically you're only saving on...
