Is the bead and rim dry or did you spray with soapy water? Can help to get the tire to seat in place easier if you spray it usually.
Could also try a tube.

 

All dry right now. I guess I'd assumed that the tubeless tape was slick enough. Will try getting it wet.

Maybe the bead just broke due to a manufacturing defect? Was that a new tire? If its that tight, definitely use soapy water to get them to seat.

No, picked them up used with 300 claimed miles. Both have plenty of tubeless residue so they had been mounted and it was tight going on the first time so I do think it broke when I was inflating it. Possibly prior damage that just hadn't fully broken yet?

Assuming the tire lever was unreinforced plastic, you should break the the lever before the bead. If a new tire, contact the seller as it sounds like a defect that warranty should cover.

Yup, the blue Park ones so strong but not reinforced. Bead is definitely broken in two places now. Is this a common issue with fat tires?

i don’t think this is a common issue, as the majority of us have never experienced such and issue. Vee is a bottom-tier tire manufacturer. Making stuff that comes on $100 and cheaper bikes. They happen to make the 2xl tires.

I'm definitely aware that Vee isn't a top brand and I did get these mainly because they are about the biggest tires available. But, I still didn't expect a bead to break. That's a complete different level. I mean, there's low end and there's potentially dangerous? I guess my main concern is that I did something that caused this. I'm mainly a road/gravel rider so these tires are more than twice as wide as anything else I have. I got the fat bike this past spring and didn't even mess with the tires aside from air pressure until recently.

 

I had the same problem on a Nate a few months ago!!!
I found that I had a dent on my rim and it was causing high stress point on my tire - bead totally stretched out on one side of tire... .. I do no get flats often. and I had to walk about 3 miles...

I also had the same problem with an old pair of ardents jut two weeks before!!

I have been riding for 30 years and never broke a bead while riding.. Twice this season!!

 

20psi in a 2XL tire is a huge, huge amount.

I can't definitively say that it's enough to blow the tire off the rim and (in so doing) ruin the bead, but I wouldn't be surprised if that's what happened.

 

20psi is also what the sidewall lists as a max pressure (which is why I mentioned it) but as I said I was definitely under 20 on the gauge and it reads high. I agree that's more than I'd ever ride with, but shouldn't the tire be fine at the pressures that the manufacturer lists it to?

 

Well known issue on the first production run of 2XLs.
