as above really. in the event of needing to adjust air pressure or, heaven forbid, fit an emergency tubes trail side, I assume the latex just pisses out the valve and it ends up all gunked up? or is there a technique?
put the valve at the top of the tyre when you deflate or adjust the pressure, latex at the bottom, valve at the top, simples
Whenever I replace the latex in my tyres, I take the valve core out and put a smear of vaseline on it.
Although it could be that I just love vaseline and latex based activity 😯
ta. obvious when you think about it.
Actually the valve should be at about 4 o'clock, and give it a bit of a flick. So that any fluid in the valve can run out inside the tyre, and the fluid in the bottom can't reach the valve.
Another reason to use removable-core valves. I use presta and it's Schwalbe tubes for me as described at

Reasons to use removable-core valves:
[list=1]
[*] You can clean them (I like the vaseline tip, never heard that one!)[/*]
[*] You can replace the core if the stem snaps - much easier than re-doing the tyre + strip.[/*]
[*]If you're having trouble getting it up (ooh-er) in the first place, removing the valve can improve the rate of air ingress and get things seated. Then let the air out, careful to keep the tyre on the rim, replace the core and re-inflate.[/*]

Cheers, al.
4. You can inject sealant in once the tyre is seated by removing the core.
Oh yes. Possibly the most obvious reason!
Doh, al.
