thought I’d start a slightly different thread.....in the past I’ve never really had any issues converting to tubeless, but a few weeks ago I managed to convert an old 26” Mavic rim to tubeless, and just as I was fitting the qr, the tyre blew off! I went momentarily deaf, and almost sh*t myself, it took a second or two to take in what happened, ( it hadn’t been filled with Stans at that point), needless to say I’m a little more cautious nowadays tho!
I had something similar with a conti trail king and some stans rims. Unfortunately the fluid was already in the tyre and it ended up all over the kitchen. Me, mini and mrs sims had ringing in our ears and I had tread pattern bruises across my knee.
edit: mini was frozen to the spot holding the half lemon he had been squeezing, mrs asked if we were dead and micro just looked underwhelmed as usual. I thought for a brief minute the bead had broken my knee.
First time I did tubeless ever I over inflated... I was doing this at 2am... full of fluid in the kitchen!
Since a similar incident I always do my 1st inflate in the open, well away from walls that will reflect the sound back. Always inflate first and add sealant later.
I understand that truck fitters have their tyres in cages as a result of many grizzly de-mounts.
I always mount the tyre first with no fluid in so the beads pop in, then fill with sealant. So far I’ve not had any tyres popping off type dramas luckily.
Slight hijack - anyone know how he's seating the bead in this video? Looks like a handy trick but I can't see what he's doing, apart from if I did that I'd be taking the tyre off...
Mine wasn’t new, I was moving front to back. It was freezing out so I thought the warm kitchen was a better option!
edit. Back to front.
Tubeless related question, I've got a set of continental race kings (not tubeless) and just tried to set them up. I've always wondered what people meant by 'porous sidewalls', they're so porous you can feel the air escaping!
Is there anything that can be done to save them? They're currently in my spares pile having arrived on a secondhand bike but I want to use it for commuting so would like the added reliability of tubeless.
Princejohn...... He's just pre seating the beads of the tyre on the rim. Makes the tyre nice and tight limiting gaps for the air to escape so it goes up easier.
Saw a continental video on this a few years back and always use this technique but can sometimes be frustrating with thinner or looser tyres as it can slip back off again as you work your way round.
He was using dual ply tyres which would of been stiffer and tighter making it look easy. Trust me it doesn't always go that easy but is a good technique to try
I’d put some new Cx tyres on over the winter and was sitting on the trainer doing a zwift when one unseated. I actually fell off my stationary bike as it was about two feet away. Absolutely filled my Lycra...
