I agree with you – it's a difficult trade-off. We're constantly evaluating the situation. The big question really is what diameter a rim should be. Then we can size the tires accordingly.

Right now, there are the old ETRTO standards that were adopted by ISO, but nobody seems to care. In some cases, that may make sense, like eliminating the hooks on carbo rims. In other cases, like reducing the G height (the height of the sidewall that holds the tire), it's inviting trouble. In any case, the old standards aren't for tubeless. Hopefully, new standards will emerge soon. And hopefully, rim makers will then stick to those standards.

I would think the vast majority of people don’t have enves) but it’s not my call.

The thing that's being lost in "Why do people go tubeless?" is the weight of the tube. I have Switchback hills and they ride like nothing else out there, but damn the tubes I have feel like they're 2LBS each. I would go tubeless just to shed that weight.

I'm truly want to go to a 29er setup on my CRUST, just to run latex tubes in 700c sizing.

Are there any light 650b tube options?

So we should adapt the wheel industry to meet the tire industry? Or to meet one maker of tires?

This is nuts.

Ride the brand in question and take the chance.

Has any other tire company such as Panaracer, Schwalbe, WTB, Maxxis, Kenda, Hutchinson, Mavic, had a problem with their tires blowing off of rims? I am asking because I don't know.

Your best bet might be to use a lightweight 26er tube, like a Vittoria Competition Latex 26 x 1.7-2.3, or a Schwalbe SV14.

The issues with tires blowing off are all over the industry. I don't want to name names, but I know of incidents for most of the brands you mention below.

It is true that supple high-end tires require tighter tolerances than stiff tires, and higher pressures – as you ride on all-road bikes – require tighter tolerances as well (compared to mtb). So out-of-spec rims will more likely result in problems with our tires than with many others, but the only alternative is make stiffer tires, and that sort of defeats the purpose of why we started our company in the first place.

We're not asking the wheel industry to adapt to our tires, just make their rims to close tolerances and to meet the existing ISO standards. As I mentioned, most high-end rims have no trouble. It's not just carbon wheels from Enve and Zipp, but also the HED and Pacenti rims we sell.

So while we could make the tires smaller to accommodate out-of-spec rims found on many OEM wheels, it would make tire mounting much harder on rims that meet the current ISO standards –*including the ones we sell. And we're not the only ones – that's why there is an international push for tubeless standards.

And as many mentioned, if you're running tubes until all this has settled, you aren't giving up much (unless you live in goathead country).

I ran Tubolito S-Tubo in the SBH for a bit.

They do have their issues at times. For example, one recently broke lower down on the stem, after I had pumped it up. (No nut to screw down on the stem; hold in place nicely against rim).

Well this covers most of us, right.

I dunno man imho you’d be out of your mind to use tubes on a MTB or gravel bike, you’d be giving up lots.

The answer is out there..probably less mess than sealant goop-age..

And yes, ya gotta glue them on properly...Not rocket surgery, as they say.

Wholeheartedly disagree for tires above 32 width. Non-tubeless is a non-starter.

Tell me more... 26in tubes will work in 27.5 wheels? I'm guessing YES due to Latex stretching abilities..

many tubes are dual advertised as both 650B and 26"

Or just use something like thunder burts that roll super fast and are reliable tubeless tires just sayin

Stuff like this has held me off from trying road tubeless. Why cant the industry (and by the industry, I mean the big players and OEMS) get their thumbs out of their asses and make this easier for consumers?

I've never had a tire blow off with a MTB or CX/Gravel tire and I was definitely cobbling **** together in the early days with gorilla tape, ratchet straps and spraying sealant all over my kitchen....
