I have a lezyne pressure drive mini pump and wondered will this give me enough pressure to re seat the tyre. I Have stans rims and need to put some more fluid in


  • Pop the valve core out and fill that way, with any luck the tyre will stay seated,
    Diy compressor is great for reseating tyres, 2l pop bottle, 2 valves and a bit of tube, track pump helps a lot too!

    There's no way to say for certain. Even the exact same tyre on the exact same rim can behave differently sometimes. Normally a mini pump will do for my Butcher Control but last night the track pump barely managed. No idea why, the bead just wouldn't hold the air in.

    Unfortunately removing the valve core isn't an option with Lezyne pumps due to the screw on head, there's nothing for it to attach to when you've removed the core. You really need to remove the tyre bead if you're replacing old fluid otherwise the tyre will just fill up with old sealant.

    But taking the core out means there's no need to break the bead to get sealant in.

    Take the core out, put the sealant in, put the core back in, pump up as usual. That is all I've ever done.
    Now where's that "Get Out of Crash Free Card"
