    Brand new tyre (raplh if it matters) on a wheel that has previously been fine. It’s seated okay and pumps up, but keeps loosing pressure and needs pumping back up every 4-5 days.

    Any tips on sorting this? I

    Is there jizz in there ?
    Is it fresh ?
    Did you do the jizzy dance when you fitted it ?
    (might need to scrub the inside of the tyre to get rid of the release thngy)

    Yes used goo. Did th dance, can hear it sloshing about. Saw it seal a number of small holes in the sidewalks. The large bottle was a good few years old.

    What’s the release thingy?!

    If you can hear sloshing when you shake the wheel, there should be enough sealant in it.

    What sealant are you using?

    Check the valve nut is tightened good. Also, if it’s a presta with a removable core, check the core is tight, and obviously that the presta pin is tightened closed.

    How much are they going down? To flat or just loosing a few psi over a week or so? One of mine does the latter though stops at around 15psi.

    Joe flats. Been alright previously, it drops pretty low, but I’ve not let it go much below 15ish. Tightened up the valve with pliers so will see. If not I’ll bung some more in I suppose.

    Find out where it’s leaking from – easy

    people say on here from time to time that some tyres have a layer of mould-release “stuff” (lubricant of some sort I suppose) that stops the jizz from wetting the tyre

    really ? didn’t know that
    I’ve had more trouble with schwalbe than most, though admittedly not (always) leaking sidewalls

    Have you been for a ride with it yet , that usually spreads the sealant properly and many tyres lose a bit of pressure before this .

    I run ralphs and nicks for years and have to pump up every few days .
    While Bontys are fine.

    What pressure did you put in first time to seat the tyre? Sometimes you need to put up to 50 psi in to make it ping and fully seat, then release pressure to your desired amount.

    Look at the tyre and follow the bead, it should be a perfect circle following the rim. If it isn’t start again and use some water with fairy liquid to help it seat properly.

    You need to find out where it’s leaking from and go from there

    OP, I’m assuming the tyres are in good nick ,seated correctly & there’s plenty of sealant in there.

    My valves sometimes need a little extra help sealing properly.

    To do this , I hold the wheel so the valve is at 12 o’clock & allow the sealant to pool at the bottom. Then flip the wheel the wheel over quickly , so the sealant gets dropped onto the valve , if that makes sense?

    (I have to say DT, unless you’re building a bike for spring, take a look out the window and replace it with a trailraper !)

    Put it in the bath.
    A stream of bubbles beats a load of strangers on the internet guessing every time for locating leaks.

    This. If it’s not going to lose pressure during the course of a ride, why are you even worrying about it?

    I’d rather not come to ride the bike and find the pressure had got so low it had unseated itself. Anyways seems it was the valve done up tight and appears to have stopped losing pressure.

    Went for a shake down ride and got bloody soaked inside 5 miles so might not have been a bad suggestion SP!
