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

can you hear air leaking from anywhere? I had a real nightmare recently with some pre-fitted tape leaking around the valve. Fixed easily after I retaped – i know it was taped in a very cold workshop, and it came off in shreds, so even if it wasnt the cold it was definitely brittle. My theory is, this meant there wasnt a good seal with the valve

I'd add another 30ml in each tyre and ride like 5k, should hopefully do it. Unless this a new tyre/rim combo you've not tried before in which case, all bets are off.

How about “read the first fucking post”!?!?! I know you are not @hippy but…

🤣😈🤣

If your tyres/wheels don't hold air - pump them up and cover with a washing up liquid and water solution. Bubbles will form at the point of leaks, shake wheel around so sealant gets to the leak and hopefully it will seal.

30 ml of sealant in a 38 mm tyre seems a bit low to me. (I put 60 ml each into a pair of 32 mm tyres last night). But, if a tyre is losing pressure overnight, I'd be surprised if it's a shortage of sealant. Is the valve airtight, that would be top of my list to check?

Thanks everyone I'll check it out

I just put like 100ml in some 45s and usually put around 50-60 in 28s for the first set up. Definitely needs some more in there.

Patching the inside of a tubeless tyre that wont hold a plug . Whats the best technique with one of those velox expensive repair kits ?.

Sand down the area, lots of glue and put the patch on, apply some pressure for a few minutes without getting your fingers stuck to it then leave it to dry. Mount and pump to pressure for a few hours, overnight if not in a rush. Then let air out and add sealant as per usual.

Worked for me, YMMV.

I've done similar but with a regular patch at the side of the road with the tyre half off, still cleaned as best as possible, sanded a bit, glued the patch (and had as cig so it dried a bit) squished it on dead hard and inflated but made sure the sealant stayed away for a few minutes, then fucked off and all was well.

Inflatable swimming pool repair kit; very supple, very durable.

Is this sealant "leaking" normal?! Noticed it a couple of times. Bizarrely, the tyres seem to hold pressure okay (though I haven't ridden for a few months).

Very common even with race sealant and new tyres.

There's a tube type version of those tyres, is there a TLE marking somewhere?

Yeah they have the TLE badge

Repaired several holes with just normal patches and glue. Clean, Sand, glue (let cure for a bit till sticky), patch, let dry well, mount, pump to pressure and let sit overnight to see if it holds pressure, then add sealant.

If the hole won't hold a plug (or 2 or 3), it might be a bit large for a patch alone, you might consider a couple of stitches of nylon thread and/or a dab of rubberized loctite to weld the hole before patching it.

Was able to fix a very large nasty cut like that, which held till the end of life of the tyre.

Do you not need to let it go tacky like a tube patch? I should probably read the instructions for the kit I'm never going to actual use...

I didn't and it worked fine, I'm sure letting it go tacky would work just as well if not better. From what I'd read what really matters is the quantity of glue, you need a decent-sized blob.

Ta. I've got a cut tyre and "fix tyre" on my todo list but since I'm not using it there's like 1000 other things I'd rather do :)

A long while back I got a puncture that wouldn't plug whilst out on a ride and I banged in a tube "to get me home". Fast forward a couple of months to Friday gone and I'm out on a ride with said tube still firmly in place cos I'm a lazy bastard. 6 miles from home, coming back up the last hill of the day, basking in the sun under Stanage Edge and it's "PSSSSHHHH THHHHBBBBTTT". Ok, fine, I've got a flat, whatever, I'm a modern man, I can repair things myself. Guess that tube had a good life.

You know who else had a good life? All the sealant that has spent the last couple of months gently oozing up the tube valve and seeping into the valve nut and then drying hard and making it impossible to remove the fucking valve nut, especially when you're at the side of the road with a faceful of wind and cold hands. I tried clawing at it, attacking it with a flat head and phillips screwdriver, hitting it with a rock, viciously swearing at it, bribing it and offering it sexual favours. To no avail.

All out of ideas, I had to walk the last 6 miles home. Fortunately, the wind was at my back, the sun was shining, and I was in a weirdly good mood. I scooted some of the flatter and more pavement-y bits, but even that was p sketchy with a flat af tire squirming away underneath me.

Have learnt my lesson now. Took some pliers to convince the valve nut off. Cleaned everything up, fresh rim tape, fresh sealant, fresh tire. Next time I have to stick a tube in it will only be as a temporary measure. Or maybe I just won't bother with the valve nut, to be on the safe side.

Was not expecting the nut to be the problem there; I was sure that story was going to go the way of 'The tube was fused to the tyre with sealant' purely because I once volunteered to fix a friends flat (5min job I thought) whilst their bike was lodging at my house for a few days, half an hour later I ended up cutting the valve just to get it past the hole so I could remove it (after having a violent meltdown over it).

Yeah, that was the problem I was expecting. As I was getting the wheel off roadside, I was thinking 'this tube is going to need tearing from the tire, and then it's going to be all disgusting with sealant and I'm just going to have to sacrifice a jersey pocket to that fate'. I could have lived with that.

Has to be said though, the number of fellow riders who either slowed down or stopped to check if I was OK / if they could help out / generally offer commiserations was pretty heartwarming. Seems like no one habitually cycles around with pliers or knives on them sadly.

Valve nut? You mean the retaining thing that you are supposed to wizz off and throw in the bin? You know you don't need them for tubes?

yeah, that little fucker. I don't normally use them but when you're sticking on a tube by the side of the road, don't have access to a bin, and you want to stash the stupid nut in a manner that it doesn't end up fucking up your washing machine when it falls out of your jersey pocket, then a good place to stash it is on the valve.

I normally stick them in jersey pocket or bikepacking bag and they've almost never ended up in the machine when I've forgotten them, they tend to stay in the jersey pocket and drop on the floor on another ride, scaring the shit out of me that I've dropped something important.

That does restore faith in humans somewhat. I remember going through 4 tubes on one damp Jan day and 3 people offered up tubes. I hunted at least one of them down on insta and offered them some form of payment but they flatly refused.
Although what you needed is some bally'd up scooter kids with the toolyo, but then they'd probably just completely relieve you of the problem.
