• Will sealant fix this?

    Yes.

  • I put sealant in it. It's fine. And tbh, the valve hole I made with a Philips screwdriver holds pressure just as well as the one I burned with a hot spoke.

    CSB

  • It's almost like the sealant seals any leaks.

  • Done 1000km on IRC Formula Pro X Guard, and so far they are pretty much faultless. No p*nctures and they are not cut up at all.

    Front tyre looks brand new, rear shows a tiny bit of wear but still looks newish.

    Plenty of grip, decent in the wet as well. They size up quite narrow and are bit stiffer than Pro-1s but I'll take that rather than loads of cuts and flats.

    In summary - expensive but worth it.

  • Just had a first go at this with Gorilla tape on Kinlin rims with G One tyres and it held 120 psi. I didn't hear it pop but it seems to have taken its place. I was slightly concerned with the two layers of tape reaching quite high on the side of the rims but went ahead anyway. Now going down slowly in terms of pressure and thinking of just adding sealant and pumping again. Pumping with simple track pump.

    This is fine

  • Okay good! Deflated overnight after adding sealant but lost a bit of sealant in the installation, might add some more and pump again to see if it works

  • I didn't hear it pop but it seems to have taken its place.

    If you tape it edge to edge, then it's likely you may not hear the bead popping in place.

    Make sure you didn't tighten the valve too much; this is usually the main cause of tyres deflating (if the tyres and rims are fine).

    This made all the difference for me, no more faffing with soapy water. I partially seated the bead with a lever and it went on first go with a regular floor pump.

  • will that work with a road tyre?

    CO2 canister seems easier, if perhaps a tad wasteful.

  • Worked with 700x38 GravelKings for me and I don't see why it wouldn't work with a smaller tyre.

  • If not, mounting the tire with a tube and then removing the tube carefully so you still have one side seated work wonders with stubborn tires

  • Make sure you do the rain dance first, too.

    Preferably before touching the tyres. This is important.

  • Thanks for the tip as I wouldn't have thought of that but now you point it out it makes sense. Anyway, with more sealant it then worked and I went for a ride this morning and all good so going to attempt the front wheel now 👍

  • Spoke too early and deflated overnight... Third layer of tape maybe? Or is it more a case of needing the bigger burst of air?

  • Add more sealant and ride again, imo

  • Even if its fully deflated now? Would it help going to a petrol station, deflated the tyre and inflated with the big air things they have there or not really?

  • Just re inflate it the same way you did before. Maybe if it's totally flat the air is leaking out the bead but it's hard to say from here.

    I doubt that a bigger air burst will make a difference. That's just for seating the bead in the first place.

  • Spoke too early and deflated overnight...

    pump it up and check valve.

  • Yeah did that and I think untightening might have helped a bit. It now stays inflated for 10+ hours while losing around half the pressure I'd say. I've pumped it up again this morning and moved it around and then left it on the floor on the side to see if that helps the sealant make its way to different places.

    I cannot hear any air coming out so the holes from which it's coming out must be super small.

  • Have you ridden on it? I find that always helps get that final seal that stops the tyre losing pressure.

  • I have on Saturday for 2h which was fine but it then deflated at home so added more sealant but not ridden on it since. Logic makes sense though

  • I have an old mtb that has ust wheels and some old mtb tyres I want to try to put on tubeless. They've been in a damp shed for +/-5 years and have been previously owned before. I took a quick look 5 minutes ago in the dark but didn't see any "tubeless" "tlr" "ust" markings on them.

    Is it worth trying this? Tyres may be 8 years old so I guess I should just buy some new ones?

  • Tyres may be 8 years old so I guess I should just buy some new ones?

    Yeah. Get new ones.
