Tubeless question. Seating tyres without a compressor??

:facepalm: - I have now reread your post, oops :roll:
I've been running tubeless on mtb, cross and road bikes for the last five years. I always use sealant and in that time I have only had two flats that wouldn't seal up. I reckon in that time with tubes I'd have had tens of punctures.
I have always managed to get tyres seated with a track pump. Sometimes it has involved swearing, but they all seat eventually. I use a really big barrelled Topeak pump and always take the cores out of the valves, then once seated inject the sealant through the valve stem, then fit the core and pump up.
On more tricky tyres I do something which is a little tricky to describe, but is essentially pulling the beads out of the well of the rim so that they are close to the bead socket when you start pumping for your life. It involves gripping the sidewalls with your fingertips and trying to pull the beads outwards. I find it's best to try and do both beads at the same time. I also hang the wheel and tyre off the ground so there aren't any places where there is external pressure on the tyre.
Good luck interpreting that gibberish.
I also have a stack of michelin tubeless tyres that I'm not using if you're in the market for one.

Re: Tubeless question
I prefer to save the 150/200 gram in tyre weight, and add a bit of sealant (less than 75 grams).
And FWIW, every "proper" tubeless tyre I've had has punctured fairly early on in its life, and needed sealant anyway!
Quick tip for seating tricky tyres.
Turn em inside out and leave them overnight, really, it works. Forces the beads apart, so once you actually flip them round and start fitting, the bead will be far more widely spread. And easier to seal. Brushing slightly dilute washing up liquid around the bead helps too.
(And then I inherited a compressor, so all bets are off!)
I guess you are using proper UST/tubeless tyres. Using tubeless ready/TLR/normal tyres, you won't get far without sealant!velofrog":2zcpyarl said:
