    Tire repair on a tubeless setup

    I'm sorry if this has been raised before, I did a quick search and couldn't see an obviouls solution.

    I have a Dillinger 4 mounted on Marge Light rim. It came to me setup for tubeless and I have no prior experience with tubeless installation.

    I noticed the tire dropping pressure slowly, then today I found the culprit, a piece of wood has pierced the tire and is lodged in place.

    So clearly I need to remove the tire and repair it with a patch on the inside.

    But now I'm concerned about re-sealing it. Do I need to add more of the sealant? (Stans??).
    Do I need a high-volume compressor/pump to re-seal?
    Is it basically the same as doing a tubeless install from scratch?

    What if I try to repair it by just lifting the one bead edge off the rim and retaining any sealant inside? Is that doable?

    Any tips on how to patch the hole - it's a small diameter, looks like a thorn or something - maybe 1/16th max.

    Cheers!

    If there is any sealant left in the tire it should plug that size of a hole. Pull the thorn and spin the wheel, add air as needed. If you are out of sealant, add more through the valve stem with some type of injector, the valve stem should have a removable core. No need to remove the tire and/or patch.

    ^^ yep, that's a pretty small hole & should seal up no problem.

    The larger sticks I've had puncture, (pinky sized) required using a glueless patch on the inside of the tire, and a bit of crazyglue to hold the hole shut.....worked well.

    Thanks guys.

    I would never have thought that the sealant could do the job on a hole!?

    Initially, that was Stan's selling point. They had a video of rolling over a bed of nails. Tubeless sort of ... followed.

    I'd just toss this out. Pull the offending object let the air out, and dry hole as well as you can with say, a paper towel.

    A few drops of super glue in the hole (pinch it open with your hand) and let it sit a few minutes before adding more sealant and air.

    Stans will certainly plug a decent sized thorn/nail hole on it;s own if need be, but since you have the time and are indoors, the glue just gives it a better chance of working more thoroughly, quickly and durably.

    I would think about just putting a patch on it. I have had a few small punctures in my tubeless tires, the sealant works fine but one day it will start leaking. It will seals back up, but itís a pain. Patching hole when you have the time has work best for me. Seems like they will start leaking when its really cold out.
