Trying to convert to tubeless, but can’t get a full seal and when I pump up then the sealant leaks out more. Very confused how to maintain seal?

The reflectors.
Just kidding – seams to be a lot of milk?
did you use a compressor, or just the floorpump?
Seat the tyre before you add sealant. Then deflate and either add sealant through the valve with one of those syringe looking things or pop the tyre off in one spot just enough to pour the sealant in.
My guess is that the tire didn’t pop into the rim. Or your wheel isn’t suitable for tubeless tires.
I have had a lot of trouble with muc off and prefer orange seal. If the tire and rim aren’t a great match then the sealant should fill in the small gaps to get a proper seal. If the sealant doesn’t dry fast (my muc off experience), then it will just keep coming through
Just a quick one from personal experience, that looks like Muc-off sealant?
It’s rubbish. We used to use it in the shop, trialled it on oit own bikes and it wouldn’t seal shit. Literally pinhole punctures wouldn’t seal.
Even the rep said it was rubbish and to mix in Stan’s, which kinda defeated the object.
As for your situation it looks like it’s not beaded right, a good pump/tank combo will sort that. Or I’ve used a Co2 inflator in a pinch and it works fairly well. Just remove the core from the valve first to get max air flow.
Fully seat the tire by inflating to a bit higher than you’re going to run it but not higher than it’s recommended high pressure. Hear some pops and check the bead to see that it’s on there evenly.
then inject sealant through the valve hole. If using a sealant that is not able to be injected like Stan’s race or Silca just accept that you’ll be making a giant fucking mess and loosing half of your expensive sealant.
I always bead in the tyre before I add the sealant.
Seat the tyre dry then add sealant through the valve 👌🏽
Seat the tire with the compressor before adding the sealant. Add the sealant through the valve after that.
First question: does the rim have tubeless tape on it? Are you certain?
Do you have compressor or big volume pump
?
I
Sealant is to seal leaks not keep the tire inflated when you install it. I always try to install tires “dry” then leave them pumped up to max safe overnight, the next day deflate and add sealant. Get a syringe with a threaded tube to shoot it through valve stem hole. My next upgrade will be to try some of the next max flow valves as they seem to be a good idea.
Did you add the sealant through the valve or did you get the tire mostly on then add sealant? I recommend the former. Get a valve core remover. If you’re using a floor pump, don’t. You’ll be happier with a compressor. Also be sure the tire is tubeless compatible. I learned a lot about tubeless on the fly and it wasn’t fun. Good luck.
Tire not seated right. Use a CO2 cartridge or an air compressor then bring pressure down to the recommended level. You will hear popping sounds as the tire sits on the channels correctly. Has nothing to do with when u add the sealant. Can do it before by simply pouring it in before setting on the wheel or after through the valve.
Pop pop
I bought the stans tubless injector kit. Was £10 but well worth it. Fit and seat the tyre. Remove the valve core then screw on the injector with the sealant amount you want. Easy peasy.
Just ride tpu tubes lmao
I have a set of reserve filmore valves in the drawer. When I use up all my cores from plugging issues, i’m going to install them. I’ve heard very good things about adding sealant through them after seating the tire. One thing though, it appears to me you need a Stan’s injector, or some such device to put in the sealant.
