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

I finally got round to fixing (hopefully) the slow puncture on my rear 650bx47 Terravail Sparwood, I lent the wheel to a friend with the I’ll lose 20psi overnight if I want to, but only some times problem and they gave it back in the same condition. It’s been sat in the garage for about 3 months so I thought I’d better sort it. Popped the tyre off, cleaned the inside, sanded it, glued it, stuck a hefty patch in there. As I was reseating the bead a felt something in the sealant, so I fished it out, or rather I fished them out. 4 yep 4 tyre worms. At least they tried to fit it I guess. It’s been up for 3 hours now and I’ve had a little ride. Bets on it staying up?

1100 miles in and I finally punctured my GK slicks after a 4x4 forced me to veer into a pot hole on a narrow lane.

I’d never repaired a tubeless tyre before this. It’s held but it looks quite messy. Can I trim it back more? Do I need to fuck around taking the whole tyre off and patch it from the inside now? The hole wasn’t massive, about a 3mm slit, a slightly smaller hole on the rear seems to have sealed no bother.

35mm GK slicks being run at 55psi.

never ever buy GK

Bit late for that innit.

As supple as they are, this is my school of thought too.

Some tubeless kits have one of these, trim it down or let it wear down naturally

Ha! It has that exact knife! And even better, I had a quick check of the kit before I left and realised the knife was seized/rusted in, so I lubed it up and got it free (I can imagine it being fairly frustrating trying to free it while standing around in the rain at the side of the road).

My worry was that it might get pushed back in if I trimmed it too much? I guess I'll trim and just have to find out. It's annoying me watching it whizz round, lol.

Trim it as close as you dare!

Okay so i've spent my lunch time today dealing with my tubeless tyres, and replacing the sealant etc and no problems.

My only question is, when I unbeaded my tyre there is still sealant in the tyre sloshing about (stans notubes race tyre sealant), and there seems to be plenty of it. Did I need to pour out the old sealant and replace it? The old sealant had probably been in there for a year, and the bike is kept outside in a bike shed that is presumably preventing it from drying up.

Nope.

Nice simple answer :)

Lesson learnt for next time, another reason why it was still sloshing around is because I don't ride the gravel bike enough.

It probably won't get pushed in, the plug is usually wedged very tight in that hole, plus everything - plug, sealant - is quite sticky. So the plug should just get flattened down. When cutting it, though, the trick is to try to disturb the plug as little as possible; use that very sharp blade, saw through, there you go. Patching it from the inside (and removing the plug) is still a possibility down the line.

Sound yeah. Feel less doubtful about it now! Trimmed back properly.

Best current tubeless tape thinking please, hive mind? - need 27mm for 25mm internal width LB rims. Thanks!

dt swiss, if not mucoff is ok.

Cheers, any advances or unofficial alternatives to that or is that the consensus?

10 meter rolls of Tesa 4289 tape from eBay is the pro choice. If you want to pay 2-3x more with nice packaging then the consumer choice is Mucoff, believe it or not, it’s one of their better products.

Ok interesting - I'm seconds away from pushing the button on the DT Swiss but may not now... I like living life on the edge, sounds like Tesa 4289 might be the one for me then!

This all day long.

Went mucoff - delivered tomorrow with prime ✌🏼 cheers for quick replies people 🙏🏼

Will get that next time - couldn't find it anywhere quick enough delivery for this time round

Is there a go to plug kit? Or are they all just the same ?
for MTB tyres if that makes any difference.

Defo had better success with Dynaplugs over worms/strips from Muc-Off. Maybe I wasn't softening up the latter enough to make them stick.

I’ve always just bought the cheapest bacon strips off the jungle site and have used whatever inserter thing that was on hand. I have a barend Mucoff one now and a cheapy plastic handled one for the other bikes.
I personally don’t think it matters what you use to plug the hole, I’ve used bit of string before and it’s held. I’m convinced it’s the sealant. However I always pull the plugs out and patch the hole asap. YMMV

Small plugs for small holes, big plugs for big holes. Loctite powerflex does help to keep the really bad ones in place, but I rarely use it anymore.
Keep your sealant topped up and don't go crazy with pressure until the fix cures up a bit.
