Tubeless for Dummies

I noticed a big blister in my front tyre today. Not sure how long it's been there. I only noticed it as I was cleaning the bike.

Anyway, this is what it looks like:





To touch it's like a big squidgy, puss filled zit! Is it going to explode if I ride it? I'm assuming the safest course of action is a new tyre. It's a Hutchinson Fusion 5 All Season 11Storm....

poke it and see

Oh, for heaven's sake, just squeeze it!

I had that once with a g-one where the outer separated from the carcass. Long time ago.

Joy - another failure mode.

You need to lance the blister - and n video please and the. Share with us all.

I think I'll order some new tyres first - then I'll squeeze it!

Back to the Gravel Kings – they are very floppy and that seems to be the problem. Mind you, the rear seems to be seated okay on an identical rim. I hadn't considered distortion to the rim but while riding yesterday I could see the front wheel now needs truing; nothing too serious just a bit of wibble.

However, the back, which is tubeless, went fairly soft about three quarters of the way through the ride. I'd done 50 or 60 miles and it had been fine, then felt soft. No visible puncture or sealant on the outside. I put some more air in, after which it was fine – just been out to check it this morning and it seems to be holding pressure overnight – but as I took the cap off, I saw the valve nut was undone! I think it had probably come undone as I took the cap off, but it's possible I had failed to do it up after pumping the tyres up that morning. I'm really not sure what the effect would be of riding with an loose valve nut, as you need to depress the core to release air – so theoretically nothing should happen.

Muc-off now do a resealable pouch of sealant with a Presta valve adaptor for emergency refills on the road.  I have bought one and seems a good idea for long distance touring where you have put a plug in but have lost sealant.

What actually happens if you mix sealants? Is it like crossing the streams?

Some are ammonia based, others are not; synthetic latex, natural latex, no latex, you name it they got it. Mixing may work, give a water/oil result, or instant hardening, or dissolve your tyre, or cause total protonic reversal.

Completely unrelated, but based on very recent experience: anchovies (worms, whatever you call them) have limited shelf live. They get less flexible and won't peel off the plastic anymore. Also: don't try to make the hole of the tool to push the worm through any larger, not even gently. The result will only be useful to skewer olives (the tasty kind).
