My first tubeless tyre.
Previously a bit of a mystery to me.
However, emboldened by a recent local Club Webinar, I have armed myself with a Pump of Special Magnificence: A Topeak Joe Blow Booster.
That, a bottle of Milkit sealant and injector syringe kit, and I set to on one the wheels on my Shand.
This had been allowed to go flat, and had then un-seated itself, leaving a small Puddle of Shame on the ground.
The sealant was due to be changed anyway.
Demounted the tyre, cleaned out the old sealant and cleaned everything up.
Remounted the tyre and Whump! the boost pump seated the tyre on my second attempt.
On my first attempt, after dumping the accumulator into the tyre, it snapped into place most ways round, but one bit didn't quite make it first time round.
Second attempt, and I flexed it gently at the non-seating bit as it was being whumped, and crack! in it went.
Let the air out, removed the valve core, added the sealant, and re-pressurised it. Seems to be holding thus far!
Pleased with the lack of explosive decompression and accompanying shower of sealant.
Will check and top up in the morning, once the sealant has had a chance to do it's thing on any residual leaks.
I'll call that a win.
