A simple slide guide to tubeless and hookless

[benb]

I would be careful with that Mavic chart.

Each page for Tubeless has the UST logo on it.

So this is Mavic's recommendations for Mavic rims. Not anyone else's, and UST is hooked AFAICT... have they made a hookless version of UST?

Does anyone know what TC and TSS mean on the horizontal axis of those charts with the rim widths?

Mavic did release a hookless rim recently, but I think it is meant for gravel use.

TC = tubeless crochet (hooked)
TSS = tubeless straight side (hookless)

Mavic should be compliant with the ETRTO standard. I remember reading that ETRTO adopted their standard. Mavic doesn't sell their own brand of tires any longer.

I believe, but can't substantiate since the ETRTO standards are behind some sort of paywall I think, that it follows the standards in terms of compatibility by indicating Yellow vs Gray boxes. The pressures I think they recommend, are based maybe on their own calculated logical progression of how rim width and tire width should impact max psi for every given combination, working backwards from a maximum. But, that's just my guess.

Nothing's perfect though. Someone could make a hookless tubeless tire with wire beads (non-foldable) perhaps, and claim a completely different ability to hold air at higher pressures (mounting them might be a pain perhaps :-).

Whatever happened to charts like this? From a couple years ago, but there seemed to be some sense in there being a 3-factor guide for Max inflation (rim width +tire width + rim type), . FYI, TSS = Hooklesss.

Yeah, sorry, another example of my fingers typing faster than my brain can think. The original post has been corrected.

The simple slide guide turned out to be not so simple.

Because there is no way to make that happen as things stand

I guess one could just say "follow all manufacturer recommendations" and leave it at that, which would get us back to exactly where we are today
