So MM on a Bonty 30 aluminium rim, 29er flavour.
Went on with a track pump no bother, sealant in and left it alone for a while and no air lost. Was at 50 psi.
Sat in garden then bang...it pops off.
Now it's got a helluva buckle in it and won't seat at all.
Didn't check if it was straight before....
So could I have done this when setting up????
Left with a tube in tonight to see if that helps
Has the bead ruptured somehow? I've written a tyre off by getting too aggro with the levers and being an idiot.
50psi is a bit daft, why inflate to the limit? Tyre is likely a writeoff
Can check bead tomorrow. It was still popping on at 50psi, pumped to that with other tyres no issues previously.
Didn't need much persuasion with levers
Years of tubeless so if this is ****ed I've done ok I guess
Was at 50 psi.
Overinflated and damaged the bead. The tyre is a throwaway. If it makes you feel any better, I did the same thing myself once. My ears were ringing for days, tubeless sealant all over the place.
Did you lubricate the bead with anything before inflating or was it dry?
It does sound like with was over inflated and the bead has snapped
Yup, tyre is junk unfortunately.
I did the same with a brand new fatbike tyre once. I always wear goggles when doing anything tubeless, but should maybe wear ear defenders too!
That tyre was not cheap but lesson learned 😭
I'd not feel too bad about it.
We've all been there.
Furiously pumping then next thing you know jiz all over the walls/garden/windows/carpets.😲
I once got it all over my girlfriend. She was looking forward to a long ride as well.
I did the same with brand new mm and bontrager rim. Tyre blew off at about 40psi trying to get it to seat. The tyre has been in the garage ever since and refuses to work with any rim - just can’t bring myself to bin a brand new tyre. I bought the tyre off wiggle - sent them pics and said what happened and they refunded.
I've had something similar in an old tyre where one of the internal plys had delaminated - 50 PSI although high, doesn't seem outrageous to me, but probably would expose a manufacturing defect. Obviously this is a bit chicken/egg (ie did the fault result in it blowing off, or did it break when blowing off?) but I'd still have a go at warrantying it personally.

On a very big MTB tyre, 50 psi will put a lot of load on the bead. On a skinny road tyre, much less. Also, cheap gauges on pumps may not give a very accurate reading so 50 psi indicated could be higher.
