29er Rim / tire mounting

[shankldu]

Whats is the most narrow rim you can go when mounting a 2.3 29er tire to more of a cross wheel , I have tried to do it because I had the two laying around for a beater build . $20 later I have a flat I think the stans tape itself cut the tube . Just curious as to opionions. its a rear wheel so not to worried about tooling around on it if I could make it work .

Why do you think the Stan's tape cut the tire? This is hard for me to imagine, even on the lightest, most fragile race-day only tire.

Anyway, in the early days of 29ers, we were running 2.2s and 2.1s on something as narrow as i17, so even an i19 rim should be ok on a 2.3. Maybe not optimal compared to an i25 rim, but certainly rideable.

How negotiable is tubeless for you? Are the tires and rims designed as "tubeless-ready"? I've done plenty of non-approved (AKA "ghetto" - hate that term) tubeless setups, but some tire/rim combinations don't work no matter what mix of split tube, gorilla tape, stans tape, weatherstripping you use. When you have a tire that is exceptionally wide for the rim, I worry that a rigged tubeless setup is asking for a burp or blowoff. For this reason, if you aren't fixed on it, I might just throw a tube in the rear wheel.

Oh. Then just redo your tape job so there are no exposed edges and put a new tube in there. Your tire/rim width combo is fine.

Maybe you could say "jury-rigged" which is an old nautical term. OTOH that might offend some lawyers.
