Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

Soap it and wack in more air until it pops . Like leather on willow

Sometimes you have to live life in the fast lane.

I usually run a bit of hand soap around the beads before attempting to seat the tyres, seems to help a lot.

Forgot which forum I was on for a moment there

Not with a wobbly AF tyre.

yeah, riding with a very wonky front tyre was a bit foolhardy. i didn't go very far or very fast though.

so last night i took off the extra rim tape, lubed it up and tried again. it actually went on less of the bead like this than before. i decided to add some sealant which (unsurprisingly) had no effect so i went to bed in a bad mood.

then this morning i got a couple of medium-sized children to put some weight on the top of the tyre as i pumped it. this made the tyre mount in a few more spots but really not very much in total. i had a breather then started again (no kids this time) and, unbelievably, it snapped into place!

if i make it to any cx races in january then i'll probably want to switch the tyres which will be something to look forward to!

BIG Tubeless exists to drive wheelset sales

I usually find pumping it up way higher than you'd think, usually seats it with a satisfying click. If the max pressure is only 60 or so, you'd be fine to pump it up to 90 or something (just don't ride it like that) and then deflate once it's seated. Tyres are designed to withstand many more PSIs than the max stated, for edge cases, hitting pot holes etc.

I do this with new tyres too and leave it for a while, maybe overnight, to make sure the bastards all good and properly sealed.

For some reason I have it in my head that the components have to withstand twice the rated maximum without popping in a static test, although I'd try to solve the problem properly before using a rim/tyre combination which needs more than it's rated maximum to seat because it's going to be a pain to dismount if it's that tight.

I would say your not a cyclist until you have blown one off the rim !! Matron

Blowing a non tubeless tyre off a tubeless rim makes QUITE THE BANG.

Did you shit yourself?

No, I just thought "that's loud" and "my ears hurt".

I think it was so loud and my ears hurt straight away I was completely stunned.

I've been more scared when I think back on it.
"THE RIM COULD HAVE BEEN DESTROYED AND I COULD HAVE BEEN TURNED INTO A KEBAB"

Not had continental tyre explode from 3m away....

New tyres took a few tries to seat with my compressor and were flat the following morning (no sealant added yet). Should I stick another layer of tape in or just whack the sealant in?

How many layers of tape?
1?
Stick another one on.
2?
Stick another one on or sealant and then whizz around the block.

3?
Whack some sealant in and then whizz around the block.

Is generally what I do.

Last time though I put too much air in and the tyre popped off. Don’t do that. It’s loud.

If you got them up and seated, then just whack sealant in.

Ok cool, I've only done one other set and they stayed inflated for a few days no sealant. Rims have the factory fitted tape. I'll whack the sealant in.

Another sale at Silca, using the birthday reward hack you can get 16oz of sealant for £8.57 which makes it cheaper than pretty much any other sealant.

Tyres seated, gunk added, ran round the block a few times. Still going flat over night. Add more sealant (30ml schwalbe doc blue in each 38mm tyre) ride longer or something else? Thanks
