Any tricks to stop sealant weep?
It's making a mess on my floor

Currently using muc-off which is supposed to help but it ain't.

I don't get why this is a problem - isn't sealant supposed to seal ??

Yeah, use a tube.





Sorry, couldn't resist.

what tires...

If they're Jan tyres, you'll be weeping for a while.

especially if it's the light casing.

I had a pair of WTB Riddler's (700x38) that started showing droplets of sealant all along the tan walls. I had Orange Seal in the tires. Pressure didn't really drop beyond the normal amount over the course of a week. I decided to change out the tires to Panaracer Gravel Kings (700x42) and have not seen so much as a tiny drop of sealant on the sidewalks. Not sure why the Riddlers "weeped". The Gravel Kings, though, ride much nicer than the WTB's.

Conti Race King (MTB)
Newish - maybe 6 mos old
They're weeping from everywhere - tread and sidewalls
Tried pumping them up to max hoping to force the particulate in the sealant into the holes but that didn't work.

Re: WTB, my buddy loves them - they weep like crazy from the sidewall, especially with tan walls

IME going for a ride helps to stop that. Spreads the sealant around and helps it seal everything. Sometimes it’s a few days/rides process, sometimes the first ride does the trick.

Edit: nvm hadn’t caught they have 6 mos in them. Maybe try a different sealant?

That was gonna be my answer.

I had some weep from some new tubeless road tires with the mucoff sealant around the bead. I ended up laying the wheels on their sides after giving them a shake, letting them sit for an hour or so, and then flipping them over.

That seemed to resolve the issues for me. I also just rode them and that seemed to take care of any pressure drop I saw before. Your issue seems quite a bit more gnarly… if tossing them around and laying them on their sides doesn’t help I’d almost think the tire is defective.

It is a bit worrying though. Tubed setups by comparison are a much less stressful process, but I do think it’s worth the hassle for the bigger tires and especially mtb.

Can't even speel tubless but is this a result of trying to make tubeless more supple, ride more better? So the sidewalls are thinner, so weep some?

I dunno..I use tubulars....with sealant i them...DOH!

I found that it helps to install new tires on a rim and inflate to 60-70 psi and let it sit for 4-5 days. This helps the bead get some of the fold kinks out. Then go ahead and unseat a section of tire and pour sealant in and pump back up to 60-70 psi.

The above worked well for one of my Conti Terra Speed gravel tires.......the other did leak slowly for the first 2 weeks then settled down.

The older Contis weep a lot. I buy mine specifically from Europe to get the newest iteration. (you can buy them in USA if shop around for a specific part number). the regular places only seem to have the oldre 2020, 2021? models. The 2022 version has a good inner lining

Orange Seal makes more of "a skin", for better or worse, but they will eventually stop.

To speed up the process, lay the wheel on its side overnight and then the next night the other side. Also, fill up with a lot of air 50psi or so, to stretch the fabric apart to let the sealant get in between.

I reread your posts. I have not tried Muc Off, but I would clean it all out and try Orange Seal.

Sure sounds like excessive WW was applied to the tires.

Not your fault but I would probably just be done with tires that behaved that way.

You're already saving the weight of the tube, something is off if they're trying to trim so much weight from the tire that it can't even hold a product design to seal holes.

heh heh. Good theory, especially seeing a Continental used on the front. I guess everyone has to try that at least once. Same with trying a Schwalbe Thunder Burt tire-of-death on the front.
