Tubeless tire pops off the bead when aired down - No go?

[Red Mosquito]

I just set up a new pair of tires, and when I aired them down to add sealant the tire popped off the bead. This happened to both tires. I've set up a ton of tubeless tires before, but this is a first for me. The one thing I did differently this time was spray the bead with some water to easily seat the bead, which I don't usually do. Otherwise, same process I've always successfully used.

Is this a huge red flag? When aired up things seem fine and the bead is holding, but of course my hand isn't going to mimic cornering forces. My concern is popping a bead and breaking my face.

Tires are Tufo Thundero HD 700x40 mounted to OEM Orbea rims.

You can add a layer of rim tape to tighten the bead. Or 2-3 layers depending on how loose it is.

Are the rims tubeless compatible? Sounds like maybe not.

I have had it happen with fat bike tires, got 'em inflated and experienced no ongoing issues.

They are

Not necessarily a problem, but move at your own tolerance for what could happen with a blowout.

I see it as a non-issue, personally. If you wouldn't have an issue with a clincher blowing off, then it shouldn't matter.

I wouldn't trust my velocity rims tubeless, low pressure, with a hard corner, but I'd think twice with a clincher doing that, too.

Seeing a lot of people posting similar stuff online.

Think I will give this a shot.

This similar to how I'm thinking, though I didn't consider the clincher side of it. I don't run super low pressure, so I'm gonna take it easy for now until I can try the more tape fix. Though, not sure how much the tape will save me if it comes down to it.

I could tell you a story about what happens when a tire blows off the rim. It involves a broken pelvis and several months on the couch 😳

TBH your story is the biggest factor that’s still giving me some pause.

If you continue to ride with air in your tires you're probably going to be okay.

Says the guy that broke a rim... 😆
