New to this so please, let me ramble.
Recently purchased a GT Avalanche 1.0 2013, great bike for me, does all I want. My question is with regards the tyres. I have tubless Maxiss tyres, with presta valves. I would like to pour / inject some sealant (like Slime) into the tyre, reducing the risk of punctures slowing me down. As far as I’m aware, this isn’t possible?
So what do you guys do, I can’t be the only person with tubless tyres with a presta valve who needs to seal them.
I do a bit of offloading & some commuting to & from work.
If you respond I can’t promise I won’t ask another stupid question… :) much appreciated.
Cheers.

    remove the core?

    get new valves with removable cores.

    How about just easing a section of tyre off the rim, pouring the sealant in and then pumping them up? Not difficult at all!

    just to be clear - you're already running them tubeless? Or do you just have tubeless ready tyres but are using tubes? If the latter then you can use slime in the tube (or even Stans) but it's not ideal and you have to have a removeable core tube for it to work.
    If you already running tubeless then the valve should have a removable core (if not switch them, Stan's ones work well) and use the Stans injector to inject the sealant through it. You can also just create a gap in the bead and pour some in but that gets to be a hassle IME.
    If you're not running tubeless and want to convert then you'll need the valves and rim tape, or possibly rim strips (that include the valve) depending on the rims you have

    IMO removing the valve core and using the injector is more hassle than popping off a bit of the bead and sloshing some more sealant in - the the OP that's all I do.

    Yeah, I've always done that. Especially once they've had 1 lot of sealant, they'll get properly glued on.
