Tyre milk

[Gooby]

I know that tubeless tyres are slightly porus so you put a sealent (milk or goo .. whatever). I have noticed my tyres are slowly deflating so I assume I have to stick some more sealent in the wheel.

I have presta valves - how do I get the stuff through the valve and in the tyre?

How much do I put in?

Yo don't say which - if any - tubeless system you run.

I run Stan's No Tubes and the 'rim tape' has the presta valve bonded to it. This particular valve has a removable core to allow you to top up and tyre spunk.

Alternatively, unseat a section of the tyre and pour it straight in.

I use 50ml of spunk in my 2.1's.

What he said.

Unscrew the middle of the presta valve and pour/syringe some in. Presta valves you'll need a core remover, but its a bigger hole to pour it in.

Or, just let all the air out and pour it in.
