I bought some tubeless Maxxis tyres recently and have fitted them. The rear one is going down slowly over a ride which o put down to shoddy tubelessing on my part. But on closer inspection the fluid is actually coming out through the tyre walls in tiny bubbles. It seems clearly faulty bit has anyone else had this? I’m not missing anything am I…

EDIT: picture showing the leakage.

Stick more fluid in, pump it up and go for another ride, check it again tomorrow. Some tyres are like that the first time you fit them.

Wor jekkyl said.

It has been fitted and ridden for a couple weeks now. Umm, only one ride actually.

Put more sealant in the tyre, do the ‘shake’, inflate the tyre and rest in a bucket and try again.

Not all tubeless tyres are created equally nor are all sealants…..on TR tyres use only stans or similar or SlimePro sealant as they have more rubber/latex in them. Don’t use things such as the thin blue Fenwicks tubeless or Bontrager juice type stuff as there is insufficient rubber content……. I know from experience and contacting the likes of Fenwicks to have a moan about its failure to seal tubeless ready tyres…….they were designed to only be used on full on tubeless tyres.

I always put 3 scoops of stans sealant in a new Maxxis tyre due to the sidewalls being a bit porous. After a couple weeks of slowly losing air they’re usually ok.

Continentals can do it for weeks whereas the Geax I am currently using go straight up and stay up from first install.

As above, a bit more sealant and a few more rides should see you right!

The last few tyres I’ve had have all died by getting more and more porous as they get old; the sidewalls end up with damp looking patches on them where the air and sealant is slowly leaking out, and no amount of extra sealant will help. New tyres shouldn’t do that, though; I’d put a bit more in and give it another try…

As above again, but with caveat – some tires do that, some don’t, sometimes there’s no rhyme or reason to it.

Bit more sealant and pump up again, once the sealant covers the inside of the tyre all is good.

Did you clean all the mould release agent off the inside of the tire
