Hookless or not?

Just reading through this, outside of my own tires coming off/blowing off the rims in my garage I have had/known (2) other locals that had road hookless tubeless tires come off during a ride. The first was in 2018 with roval CLX50 wheels before they did the recall or claim no tubeless on the wheelset, his tire came off in a fast corner. He was also using 100psi on the wheelset.

Yes those are hooked like everyone posted.

I’ve had a hooked tire failure from a TIRE BEAD that stretched - Hutchinson Sector 28 tires.

HOOKED ENVE 5.6 Disc.

Hutchinson Sector 28 tire bead stretch and fail 19 miles in the middle of nowhere:

no cell coverage, group ride thankfully. Took a pic while waiting for an hour to get picked up:

Back at home:

Tire installed a week earlier, the fact it went on so easy and all these bubbles should have been a warning sign:

New tire, 3 rides on the kickr, an hour outside, and then that ride.

Pressure set to 60psi.

I’ll never buy/ride Hutchinson again!

ENVE had a picture of the tire issue:

Blow off is possible on hooked rims too, as I proved with those not-fit-for-tubeless Hutchinson Sector 28 tires.

So thats why tire beads have gotten so inflexible! I originally posted it here:

Its all about the rim AND tire. https://www.enve.com/en/journal/behind-the-product-the-hookless-bead-how-it-works-and-who-theyre-for/ Even if you don’t read much of the article, this is one key point: [image] as I learned the hard way with a hooked ENVE 5.6 Disc and an out-of-spec tire (Sector 28).

For completeness I’m adding that to my list of tubeless experiences in this thread, although the tire industry has long since moved to inflexible tire beads.
