    Out riding last night and managed to put a tiny slice in the tyre (probably <2mm). Rather frustratingly, the sealant didn’t do its job and I had to stroll back to the car.

    My mate reckons it’s because it was so cold (probably about 5 degrees). I just wondered if I’ve got crap sealant (Joe’s no-flats).

    Any opinions? It was a Schwalbe Dirty Dan (tubeless superstar job), if that makes any difference.

    2mm is not a small hole for sealant, I’m not surprised.

    Not carrying a spare tube then….

    Might seem ironic, but more than worth the added weight to carry a tube.

    Did you rotate the wheel so the hole was at the bottom {6 ‘Oclock position] and let the sealant puddle above the hole, letting the tyre pressure force the sealant through the hole, giving it 3-5 mins to do it’s job? usually works for me. Sealed holes op to 5mm [on tread, not sidewall] doing this, usually have to pump up a bit more 15 mins later.

    Using Stans BTW

    + I’m usually pretty generous with the amount of sealant I put in. sod the weight, It’ll all dry out eventually.

    As above, make sure hole is at bottom and I also roll my finger over the hole to encourage the sealant to bung up

    I carry anchovies (and a spare tube) for moments likes these – lucky enough not to have had to use them yet – but better than walking

    I once had to keep topping the tyre up to finish the ride – when I got home and opened up the tyre I found two ping pong ball sized balls of dry latex.

    I top up more regularly now

    Did as suggested above but the sealant just dribbled out. I did think that anything under 3mm wasn’t seen as much of a problem. Maybe I was just unlucky.

    As for spare tubes, I always carry one. It’s just that it was quicker to walk than mess around with the change.

    Here’s another question. What’s the best way to repair the tyre?

    Joe’s sealant has worked OK for me in the past. Lasts longer than Stan’s too I think.

    Doesn’t always seal of course, so I always carry a tube.

    You can use a regular tire patch on the inside of the tire to fix small tears or holes in the sidewall that won’t stay sealed. Just be sure to clean the area well to remove all of the sealant so that the glue has good rubber to stick to.

    It’s quicker to repair that kind of puncture than fitting a new tube with the likes of a Panaracer tubeless repair patch kit. Leave the tyre on,clean in and around the hole and plug it. Inflate.

    Maybe you’d not enough sealant in, plus just use a normal patch.

    Sounds like a user Fail.

    Panaracer tubeless repair kit or weld tire worms would sort it.

    Even a spare inner tube.

    Fail to prepare or prepare to fail.

    Sorry – no sympathy 2mm holes happen and don’t always seal.

    What a cheerful chap you are, Shortcut.

    Could someone enlighten me on anchovies?

    EDIT:

    I never knew trailside repair kits existed. Just ordered a Weldtite one. Many thanks.

    As another point, someone suggeted to me today that CO2 inflaters shouldn’t be used with tubeless. Any truth to this?

    Sometimes with bigger holes of around 2mm you’ll find the sealant gets blown out of the hole faster than it can set.
    Let it go down until it’s quite soft so the air’s escaping slower and it may seal itself allowing you to blow it back up again.
    Definitely worth carrying those little thread things and the needle for them. They really do work on bigger holes.

    He seems quite angry.

    Worth carrying some kind of tubeless repair kit though, that or a spare toob.

    I had a v similar sliced tyre yesterday. Fixed it with a wormy anchovy thing. I was impressed how well it worked.

    I think there’s a theory that CO2 sets the sealant into a big rubber ball. I’ve had this when using CO2 – but I’ve also had it to a lesser extent when using plain old air. I wouldn’t worry about it

    The demo videos for tubeless always show the tyres pierced with nails or awls, slices don’t seal nearly as well though- they’re more likely to reopen as the tyre squishes around.

    Put some glitter in with the fluid, help seal bigger holes quicker

    … and if the glitter doesn’t seal the hole, at least passers-by will think that the unicorn mating season is in full swing
