Never had this problem with tubes, this is the final straw, gonna bin this one and start over.

Ulp! What tyre is that?

That happened to one of mine, think it was a Maxxis. Binned it.

I’ve just realised what that tread pattern reminds me of.
IRC Kujo FTW.

WTB Motoraptor.

Does this actually have anything to do with tubeless? Just looks like ****/poorly made tyre

That was my first thought – “who the ****runs an old Kujo tubeless?!” 🙂

Best hardpack tyres ever.

The tyre had been punctured and had spat out a bit of sealant. I topped up the sealant and went for a ride. I think what happened was that the sealant blocked the exit hole, but the air got between the tread and the tyre carcass. This caused the tread to separate. Wouldn’t have happened with a tube. It finally went off with a nice bang as I was taking a nap and woke me up.

I’d put that down to the tyre carcass failing. I’ve been riding tubeless for years and have never experienced that.

PLEASE change your pedals 😯

Even without the giant hole that tyre is worn out and only fit for the bin.

as I was taking a nap and woke me up.

So that’s why you’re so upset about it?
Never nice to be woken from a daytime nap.

PLEASE change your pedals

I love those pedals.

+1 cultsdave, tyre looks very worn even without the problem.

It does look like you have had a fair wear out of them.

They look like this new:

I can’t see it fair to blame tubeless for that when the tyre was never designed for it, and it clearly has loads of wear.

If you go back to tubes, and then you get a tyre failure, what’ll you do then? 🙂

I’ve had more tyre failures whilst using tubes than tubeless. Stuff fails. Tubeless is still better.

Those things make my shins weep! 😯

This is the hole that blew out in the tyre. Most fascinating exploding tyre I’ve ever seen. The pictures at the top are of two different places on the tyre. I got back from a ride and left the bike to dry off while I had a coffee. When I went to put it away, I noticed the rear tyre bulging in one spot (the top picture). I turned the back wheel to get some light to take a photo and then saw the big blister in a different place (the second picture). That blister wouldn’t have survived any riding, so it was literally blowing itself apart as I watched. Air from inside the tyre seemed to be seeping into the tyre carcass and getting trapped under the tread, so the tread was blistering all over the place. I was a bit sleepy after my morning ride so I took a quick nap, only to be woken by the tyre exploding. Very disappointing, I’d just managed to wear it down to that sweet spot where it’s nearly as fast as a slick.

I’ll do something about those pedals tomorrow, apologies to anyone who finds them unacceptable.

That’s because it nearly is a slick .

Woo hoo, all fixed. Shiny new pedals and tyre seems to have sealed up nicely. I’ll try a quick ride after work tomorrow.
